Maize

:This article is about the cereal. For the town, see Maize, Kansas. Maize (Zea mays ssp. mays) is a cereal grain that was domesticated in Mesoamerica. It is called corn in the United States, Canada, and Australia but there are further regional differences in terminology. While some maize varieties grow 7 m (23 ft) tall at certain locations, commercial maize has been bred for a high-end height of 2.5 m (9 ft). Sweet corn is usually shorter than field corn varieties.

Maize physiology

The stems look like bamboo cane and the joints (nodes) are about 40–50 cm (16–20 inches) apart. Maize has a very distinct growth form, the lower leaves being like broad flags, 50–100 cm long and 5–10 cm wide (2–4 feet by 2–4 inches); the stems are erect, from 2–3 m (7–10 feet) in height, with many nodes, casting off flag-leaves at every node. Under these leaves and close to the stem grows the corn, covered over by several layers of leaves, and so closed in by them to the stem, that it does not show itself easily till there bursts out at the end of the ear a number of strings, called silk, that look like tufts of horsehair, at first green, and afterwards red or yellow. The top of the stem ends in a flower, called the tassle. For each silk on which pollen from the tassle lands, one kernel of corn is produced. Young ears can be consumed raw, cob, silk, and all; as the plant matures (usually during the summer months) the cob toughens and the silk dries to inedibility. By late August the kernels have dried out and become difficult to chew without cooking them tender first in boiling water. The kernel of corn has a pericarp of the fruit fused with the seed coat, typical of the grasses. It is close to a multiple fruit in structure, except that the individual fruits (the kernels) never fuse into a single mass. The grains are about the size of peas, and adhere in regular rows round a white pithy substance, which forms the ear. An ear contains from two to four hundred grains, and is from 10–25 cm (4–10 inches) in length. They are of various colors, blackish, red, white and yellow. When ground into flour, it yields more flour, with much less bran, than wheat does. However, it lacks the protein gluten, and therefore makes baked goods with poor raising capability.

Genetics

Maize has 10 chromosomes (n=10). The combined length of the chromosomes is 1500 cM. Some of the maize chromosomes have what are know as "chromosomal knobs". They are highly repetitive heterochromatic domains that stain darkly. Individual knobs are polymorphic among strains of both maize and teosinte. Barbara McClintock used these knob markers to prove her transposon theory of "jumping genes".

Origin of maize

transposon Maize is a direct domesticate of the teosinte Zea mays ssp. parviglumis, native to the Balsas River Valley of southern Mexico, with up to 12% of its genetic material obtained from Zea mays ssp. mexicana through introgression. The term teosinte describes all species in the genus Zea, excluding Zea mays ssp. mays. Maize development is thought to have started from 7,500 to 12,000 years ago. The domestication of maize is of particular interest to researchers. It is unknown what precipitated its domestication, because the edible portion of the wild variety is too small to be worth cultivating. It would have taken many generations of selective breeding in order to produce a plant with cobs large enough to eat. Archaeological remains of the earliest maize cob, found at Guila Naquitz Cave in the Oaxaca Valley of Mexico, date back roughly 6,250 years. Maize was the staple food, or a major staple, of all the pre-Columbian Mesoamerican civilizations. During the 1st millenium CE, maize cultivation spread from Mexico across North America, transforming the landscape as Native Americans cleared large forest and grassland areas for the new crop. In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and Tripsacum. However, the proposed role of the related genus Tripsacum in the origins of maize has been refuted by modern genetic analysis.

Cultivation

Paul Mangelsdorf] Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. While the United States produces almost half of the world's harvest, other top producing countries are as widespread as China, India, Brazil, France, Indonesia, and South Africa. Worldwide production was over 600 million metric tons in 2003, just slightly more than rice or wheat. Maize is planted in the spring to take advantage of spring rains. Its root system is shallow and the plant is dependent on steady rain or irrigation. In the United States, a good harvest was predicted traditionally if the corn was "knee-high by the Fourth of July", although modern hybrids often exceed this growth rate. Maize used as silage is harvested while the plant is green and the fruit unmatured. Otherwise, maize is left in the field very late in the autumn in order to dry thoroughly. In fact, it is sometimes not harvested until winter or even early spring. The importance of regular rain is shown in many parts of Africa, where periodic drought regularly causes famine by causing maize crop failure; the older traditional African native millet (which is however less palatable than maize, and much less productive in good years) would have survived and produced a small crop in these conditions. millet] Maize was planted by the Native Americans in hills, in a complex system known to some as the Three Sisters: beans used the corn plant for support, and squashes provided ground cover to stop weeds. This method was replaced by single species hill planting where each hill 60–120 cm (2–4 feet) apart was planted with 3 or 4 seeds, a method still used by the home gardener. A later technique was checked corn where hills were placed 40 inches apart in each direction, allowing cultivators to run through the field in two directions. In more arid lands this was altered and seed were planted in the bottom of 10–12 cm (4–5 inch) deep furrows to collect water. Modern technique plants maize in rows which allows for cultivation while the plant is young. In North America, fields are often planted in a two-crop rotation with a nitrogen-fixing crop, often soybeans. Sometimes a third crop, winter wheat, is added to the rotation. Fields are usually plowed each year, although no-till farming is increasing in use. Before about World War II, most maize was harvested by hand. This often involved large numbers of workers and associated social events. Some one- and two-row mechanical pickers were in use but the corn combine did not get adopted until after the War. By hand or mechanical picker, the entire ear is harvested which then requires a separate operation of a corn sheller to remove the kernels from the ear. Whole ears of corn were often stored in corn cribs which is a sufficient form for some livestock use. Some modern farms store maize in this manner and later shell it for sale in the off-season to capture better prices. The combine with a corn head (with points and snap rolls instead of a reel) cuts the stalk near the base and then separates the ear of corn from the stalk so that only the ear and husk enter the machinery. The combine separates the husk and the cob, keeping only the kernels.

Pests of maize

Insect pests

combine
- Corn earworm (Heliothis zea)
- Fall armyworm (Spodoptera frugiperda)
- Common armyworm (Pseudaletia unipuncta)
- Stalk borer (Papaipema nebris)
- Corn leaf aphid (Rhopalosiphum maidis)
- European corn borer (Ostrinia nubilalis) (ECB)
- Corn silkfly (Euxesta stigmatis)
- Lesser cornstalk borer (Elasmopalpus lignosellus)
- Corn delphacid (Peregrinus maidis) The susceptibility of maize to the European corn borer, and the resulting large crop losses, led to the development of transgenic corn expressing the Bacillus thuringiensis (Bt) toxin. Bt corn is widely grown in the United States and has been approved for release in Europe.

Diseases

- Corn smut or common smut (Ustilago maydis): a fungal disease, known in Mexico as huitlacoche, which is prized by some as a gourmet delicacy in itself.
- Maize Dwarf Mosaic Virus
- Stewart's Wilt (Pantoea stewartii)
- Common Rust (Puccinia sorghi)

Uses for maize

The primary use for corn (seed) in United States and Canada, is as a feed for livestock, while some is for the production of corn sweeteners like corn syrup, and the production of ethanol. Ethanol, a type of alcohol, is mostly used as an additive in gasoline to increase the octane rating. It is also used for making Bourbon whiskey. Bourbon whiskey Human consumption of corn and corn meal constitutes a staple food in many regions of the world. It is the main ingredient for tortilla and many other dishes of Mexican food. Maize can also be prepared as hominy, in which the kernels are bleached with lye; or grits, which are simply coarsely ground corn. These are commonly eaten in U.S. Southern States, foods handed down from Native Americans. Another common food made from maize is corn flakes. The flour of maize (cornflour or masa) is used to make cornbread and Mexican tortillas. Teosinte is used as fodder, and can also be popped as popcorn. As a food, maize (Zea mays ssp. mays) is used in various forms, with several major Cultivar Groups. The most important Cultivar Groups are:
- Flour corn - Zea mays L. subsp. mays Amylacea Group
- Popcorn - Zea mays L. subsp. mays Everta Group
- Dent corn - Zea mays L. subsp. mays Indentata Group
- Flint corn - Zea mays L. subsp. mays Indurata Group
- Sweetcorn - Zea mays L. subsp. mays Saccharata Group
- Pod corn - Zea mays L. var. tunicata Larrañaga ex A. St. Hil Many scientists speculate that fuel ethanol will mostly be produced from switchgrass and other biomass sources in the future. Corn cobs are also used as a biomass fuel source. Maize is relatively cheap and home heating furnaces have been developed which uses maize kernels as a fuel. They feature a large hopper which feeds the uniformly sized corn kernels (or wood pellets or cherry pits) into the fire. Some forms of the plant are occasionally grown for ornamental use in the garden. For this purpose, variegated and coloured leaf forms, as well as those with colourful cobs are used. Corncobs can be hollowed out and treated to make inexpensive smoking pipes, first manufactured in the United States in 1869. In 1983, Barbara McClintock received the Nobel Prize in Medicine for discovery of transposons while studying maize. Maize is still an imporant model organism for genetics and developmental biology today. In 2005, research by the USDA Forest Service indicated that the rise in maize cultivation 500 to 1,000 years ago in the southeastern United States contributed to the decline of freshwater mussels, which are very sensitive to environmental changes. [http://www.srs.fs.usda.gov/about/newsrelease/nr_2005-06-06-mussels.htm] An unusual use for maize prior to harvest is for a maze. In the U.S., these are called "corn mazes" and are popular in many farming communities. The first modern corn maze was designed by Adrian Fisher, who is in the Guiness Book of World Records for several of his maze designs. Mr. Fisher currently operates a company [http://www.mazemaker.com/ Adrian Fisher Mazes, Ltd.], specializing in mazes, including maize mazes.

Cereal

:This article is about grains. See also breakfast cereal Cereal crops are mostly grasses cultivated for their edible seeds (actually a fruit called a caryopsis). Cereal grains are grown in greater quantities worldwide than any other type of crop and provides more food energy to the human race than any other crop. In some developing nations, cereal grains constitute practically the entire diet of common folk. In developed nations, cereal consumption is more moderate but still substantial. The word cereal has its origin in the Roman goddess of grain, Ceres. Staple food grains are traditionally called corn in Britain, though that word became specified for maize in the United States. And a merchant of corn was in Britain called a chandler, which in the United States is an obsolete word for someone who sells candles. maize

Cereal crops

True cereals

The cereal crops are (in approximate order of greatest annual production):
- wheat, the primary cereal of temperate regions
- rice, the primary cereal of tropical regions
- maize, a staple food of peoples in North America, South America, and Africa and of livestock worldwide; called "[Indian] corn" in North America and Australia
- millets, a group of similar but distinct cereals that form an important staple food in Asia and Africa.
- sorghums, important staple food in Asia and Africa and popular worldwide for livestock
- rye and triticale, important in cold climates
- oats, formerly the staple food of Scotland and popular worldwide for livestock
- barley, grown for malting and livestock on land too poor or too cold for wheat
- teff, popular in Ethiopia but scarcely known elsewhere
- wild rice, grown in small amounts in North America
- spelt, a close relative of wheat Cereal

Pseudocereals

In addition, several non-grasses that are grown for their seed may also be referred to as cereals. These pseudocereals include (in no particular order):
- buckwheat
- amaranth
- quinoa
- kañiwa
- cockscomb

Cultivation

cockscomb.]] While each individual species has its own peculiarities, the cultivation of all cereals crops is similar. All are annual plants; consequently one planting yields one harvest. Wheat, rye, triticale, oats, barley, and spelt are the cool-season cereals. These are hardy plants that grow well in moderate weather and cease to grow in hot weather (approximately 30 °C but this varies by species and variety). The other warm-season cereals are tender and prefer hot weather. Barley and rye are the hardiest cereals, able to overwinter in the subarctic and Siberia. Wheat is the most popular. All cool-season cereals are grown in the tropics, but only in the cool highlands, where it may be possible to grow multiple crops in a year.

Planting

The warm-season cereals are grown in tropical lowlands year-round and in temperate climates during the frost-free season. Cool-season cereals are well-adapted to temperate climates. Most varieties of a particular species are either winter or spring types. Winter varieties are sown in the autumn, germinate and grow vegetatively, then become dormant during winter. They resume growing in the springtime and mature in late spring or early summer. This cultivation system makes optimal use of water and frees the land for another crop early in the growing season. Winter varieties do not flower until springtime because they require vernalization (exposure to low temperature for a genetically determined length of time). Where winters are too warm for vernalization or exceed the hardiness of the crop (which varies by species and variety), farmers grow spring varieties. Spring cereals are planted in early springtime and mature later that same summer, without vernalization. Spring cereals typically require more irrigation and yield less than winter cereals.

Harvest

Once the cereal plants have grown their seeds, they have completed their life cycle. The plants die and become brown and dry. As soon as the parent plants and their seed kernels are reasonably dry, harvest can begin. In developed countries, cereal crops are universally machine-harvested, typically using a combine harvester, which cuts, threshes, and winnows the grain during a single pass across the field. In developing countries, a variety of harvesting methods are in use, from combines to hand tools such as scythes. If a crop is harvested during wet weather, the grain may not dry adequately in the field to prevent spoilage during its storage. In this case, the grain is sent to a dehydrating facility, where artificial heat dries it. In North America, farmers commonly deliver their newly harvested grain to a grain elevator, a large storage facility that consolidates the crops of many farmers. The farmer may sell the grain at the time of delivery or maintain ownership of a share of grain in the pool for later sale.

Food value

Cereal grains supply most of their food energy as starch. They are also a significant source of protein, though the amino acid balance is not optimal. Whole grains (see below) are good sources of dietary fiber, essential fatty acids, and other important nutrients. Rice is eaten as cooked entire grains, although rice flour is also produced. Oats are rolled, ground, or cut into bits (steel-cut oats) and cooked into porridge. Most other cereals are ground into flour or meal, that is milled. The outer layers of bran and germ are removed (see grain (fruit) and seed). This lessens the nutritional value but makes the grain more resistant to degredation and makes the grain more appealing to many palates. Health-conscious people tend to prefer whole grains, which are not milled. Overconsumption of milled cereals is sometimes blamed for obesity. Milled grains do keep better because the outer layers of the grains are rich in rancidity-prone fats. The waste from milling is sometimes mixed into a prepared animal feed. Once (optionally) milled and ground, the resulting flour is made into bread, pasta, desserts, dumplings, and many other products. Besides cereals, flour is sometimes made from potatoes, chestnuts and pulses (especially chickpeas). In American English, cold breakfast cereals and porridges are simply called cereal. Cereals are the main source of energy providing about 350 kcal per 100 grams Cereal proteins are poor in nutritive quality, being deficient in essential amino acid lysine. The proteins of maize are still poor, being deficient in lysine and tryptophan (a precursor of niacin) Rice proteins are richer in lysine than other cereal proteins and for this reason, rice protein is considered to be of better quality. Rice is a good source of B group vitamins, especially Thiamine. It is devoid of Vitamines A, D, C and is a poor source of Calcium and Iron.

Grain

The word grain has several meanings, most being descriptive of a small piece or particle.

Particle-related

The primary definition is the agricultural one, with the others derived from it.
- In agriculture, a grain is the seed of a grass, a simple dry fruit technically called a caryopsis. Such crops are often called cereals. Grain can also refer to other types of small seeds, though this is technically less correct.
- In units of measurement, the grain is a unit of mass equal to 64.79891 milligrams. It was originally based on the weight of one grain of barley. It was used in the past for older drugs such as aspirin, for bullets, and for precious metals.
- In geology, a grain is a single particle of rock or other material, such as sand or salt; see grain size.
- In materials science (especially metallurgy), a grain is a single crystal inside solid-state matter, also referred to as crystallite — related to the obsolete term "corn" as in corned beef.
- In photography, the fineness of image resolution for photographic film (i.e., graininess of a picture), originally related to the (crystallographic) grain size of silver iodide.

Others

- In wood, grain describes the alignment and texture of the wood fibres. This is often important in its effect on woodworking techniques (e.g. going against the grain).
- In golf, the direction in which individual blades of grass lie, usually in reference to a putting green.
- In textiles, grain refers to the direction of woven fabric's warp (lengthwise) and weft (crosswise) threads.
- In rocket science, grain refers to the solid propellant of a rocket (either solid fuelled or hybrid), more or less a hollow cylinder, sometimes textured inside, and possibly very large.
- In computer science, grain refers to the size of code executed by a thread or process before it is interrupted in a multiprocess system (its granularity). Thus we have fine-grained and coarse grained parallelism.
- In physics, a fine-grained description is one which contains a lot of small-scale detail. Reducing the amount of detail gives a coarse-grained description.
- Grain may refer to the place Isle of Grain in Kent, England, on which lies the village of Grain, Kent.
- Grain is one of the stocks in the game Stock Ticker.
- In music, see granular synthesis. Category:Grains

Mesoamerica

Mesoamerica is the region extending from central Mexico south to the northwestern border of Costa Rica that gave rise to a group of stratified, culturally related agrarian civilizations spanning an approximately 3,000-year period before the European discovery of the New World by Columbus. Mesoamerican is the adjective generally used to refer to that group of Pre-Columbian cultures. This refers to an environmental area occupied by an assortment of ancient cultures that shared religious beliefs, art, architecture, and technology that made them exceptional in the Americas for three thousand years. Some common shared Mesoamerican traits include the three-stone hearth, a certain kind of sandal, intensive agriculture based heavily on maize (corn); worship of a set of deities including a rain god, a sun god, a feathered-serpent god (known to the Aztecs as Quetzalcoatl); a Vigesimal numbering system; the use of a 260 day ritual calendar in addition to the solar year calendar (see: Mesoamerican calendars); the construction of temples elevated atop stepped pyramids; a ritual ball-game (see:Mesoamerican ballgame); and various other artistic and cultural conventions. Mesoamerica is also a canonical example of a Linguistic area: all of the major Mesoamerican languages show some subset of a pool of common traits, despite being made up of many different language families. Mesoamerica's economy and geopolitics benefited from extensive use of a lingua franca, the Nahuatl language, at least since the 7th century, and perhaps even going as far back as 2,000 years. Mesoamerica is one of our planet’s six cradles of early civilizations. Many viewpoints of the ancient cultures of Belize, El Salvador, Guatemala, Honduras, and Mexico continue to the present time today. Several of these cultural inventions and traits have spread throughout the world, both past and presently speaking. Mesoamerican metacivilizations included the Olmec, Zapotec, Teotihuacan, Maya, Mixtec, Huastec, Totonac, Toltec, Tarascan, and the Aztec. In some writings from the 1920s and 1930s the alternative term Middle America was used to refer to Mesoamerica, but that acception of the term has generally fallen out of favor. See Middle America.

United States

:For alternative meanings, see the disambiguation page for US, USA, United States, or American. The United States of America is a federal democratic republic situated primarily in central North America. It comprises 50 states and one federal district, and has several territories. It is also referred to, with varying formality, as the United States, the U.S., the U.S.A., the States, or simply and most commonly, America. The official founding date of the United States is July 4, 1776, when the Second Continental Congress—representing thirteen British colonies—adopted the Declaration of Independence. However, the structure of the government was profoundly changed in 1788, when the states replaced the Articles of Confederation with the United States Constitution. The date on which each of the fifty states adopted the Constitution is typically regarded as the date that state "entered the Union" (became part of the United States). Since the mid-20th century, following World War II, the United States has emerged as a dominant global influence in economic, political, military, scientific, technological, and cultural affairs.

Geography and climate

The United States shares land borders with Canada (to the north) and Mexico (to the south), and territorial water boundaries with Canada, Russia, the Bahamas, and numerous smaller nations. It is otherwise bounded by the Pacific Ocean and the Bering Sea, in the west; the Arctic Ocean, in the northernmost areas; and the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea, in the eastern and southeastern areas. Forty-eight of the states are in the single region between Canada and Mexico; this group is referred to, with varying precision and formality, as the continental or contiguous United States, sometimes abbreviated CONUS, and as the Lower 48. Alaska, which is not included in the term contiguous United States, is at the northwestern end of North America, separated from the Lower 48 by Canada. The archipelago of Hawaii is in the Pacific Ocean. The capital city, Washington, District of Columbia is a federal district located on land donated by the state of Maryland. (Virginia also donated land, but it was returned in 1847.) The United States also has overseas territories with varying levels of independence and organization. When inland water is included in the total area, only Russia and Canada are larger than the United States; if inland water is excluded, China ranks third and the U.S. ranks fourth. The United States' total area is 3,718,711 square miles (9,631,418 km²), of which land makes up 3,537,438 square miles (9,161,923 km²) and water makes up 181,273 square miles (469,495 km²). The United States' landscape is one of the most varied among those of the world's nations: among its many features are temperate forestland and rolling hills, on the east coast; mangrove, in Florida; the Great Plains, in the center of the country; the Mississippi–Missouri river system; the Great Lakes, four of the five of which are shared with Canada; the Rocky Mountains, west of the Great Plains; deserts and temperate coastal zones, west of the Rocky Mountains; and temperate rain forests, in the Pacific northwest. Alaska's tundra, and the volcanic, tropical islands of Hawaii add to the geographic diversity. Hawaii The climate varies along with the landscape, from tropical in Hawaii and southern Florida to tundra in Alaska and atop some of the highest mountains. Most of the North and East experience a temperate continental climate, with warm summers and cold winters. Most of the South experiences a subtropical humid climate with mild winters and long, hot, humid summers. Rainfall decreases markedly from the humid forests of the Eastern Great Plains to the semi-arid shortgrass prairies on the high plains abutting the Rocky Mountains. Arid deserts, including the Mojave, extend through the lowlands and valleys of the southwest, from westernmost Texas to California and northward throughout much of Nevada. Some parts of California have a Mediterranean climate. Rainforests line the windward mountains of the Pacific Northwest from Oregon to Alaska.

History

American history started with the migration of people from Asia across the Bering land bridge approximately 12,000 years ago following large animals that they hunted into the Americas. These Native Americans left evidence of their presence in petroglyphs, burial mounds, and other artifacts. It is estimated that 2-9 million people lived in the territory now occupied by the U.S. before European contact, and the subsequent introduction of foreign diseases such as small pox that greatly diminished the native populations. Some advanced societies were the Anasazi of the southwest, who inhabited Chaco Canyon, and the Woodland Indians, who built Cahokia, located near present-day St Louis, a city with a population of 40,000 at its peak in AD 1200. Vikings first visited North America around 1000, but did not settle permanently. Following the discovery voyages of Christopher Columbus around 1492, other Europeans began to explore and settle there. During the 1500s and 1600s, the Spanish settled parts of the present-day Southwest and Florida, founding St. Augustine, Florida in 1565 and Santa Fe (in what is now New Mexico) in 1607. The first successful English settlement was at Jamestown, Virginia, also in 1607. Within the next two decades, several Dutch settlements, including New Amsterdam (the predecessor to New York City), were established in what are now the states of New York and New Jersey. In 1637, Sweden established a colony at Fort Christina (in what is now Delaware), but lost the settlement to the Dutch in 1655. This was followed by extensive British settlement of the east coast. The British colonists remained relatively undisturbed by their home country until after the French and Indian War, when France ceded Canada and the Great Lakes region to Britain. Britain then imposed taxes on the 13 colonies, widely regarded by the colonists as unfair because they were denied representation in the British Parliament. Tensions between Britain and the colonists increased, and the thirteen colonies eventually rebelled against British rule. British Parliament, George Washington (1789-1797).]] In 1776, the 13 colonies split from Great Britain and formed the United States, the world's first constitutional and democratic federal republic, after their Declaration of Independence of that year, and the Revolutionary War (1775 to 1783). The original political structure was a confederation in 1777, ratified in 1781 as the Articles of Confederation. After long debate, this was supplanted by the Constitution in 1789, forming a more centralized federal government. Prior to all these was the Albany Congress in 1754, in which a union was first seriously proposed. From early colonial times, there was a shortage of labor, which encouraged unfree labor, particularly indentured servitude and slavery. In the mid-19th century, a major division occurred in the United States over the issue of states' rights and the expansion of slavery. The northern states had become opposed to slavery, while the southern states saw it as necessary for the continued success of southern agriculture and wanted it expanded to the territories. Several federal laws were passed in an attempt to settle the dispute, including the Missouri Compromise and the Compromise of 1850. The dispute reached a crisis in 1861, when seven southern states seceded¹ from the Union and formed the Confederate States of America, leading to the Civil War. Soon after the war began, four more southern states seceded. During the war, Abraham Lincoln issued the Emancipation Proclamation, mandating the freedom of all slaves in states in rebellion, though full emancipation did not take place until after the end of the war in 1865, the dissolution of the Confederacy, and the Thirteenth Amendment took effect. The Civil War effectively ended the question of a state's right to secede, and is widely accepted as a major turning point after which the federal government became more powerful than state governments. Thirteenth Amendment). The title of the painting, from a 1726 poem by Bishop Berkeley, was a phrase often quoted in the era of Manifest Destiny, expressing a widely held belief that civilization had steadily moved westward throughout history. [http://americanart.si.edu/t2go/1lw/1931.6.1.html (more)] ]] During the 19th century, many new states were added to the original 13 as the nation expanded across the continent. Manifest Destiny was a philosophy that encouraged westward expansion in the United States. As the population of the Eastern states grew and as a steady increase of immigrants entered the country, settlers moved steadily westward across North America. In the process, the U.S. displaced most American Indian nations. This displacement of American Indians continues to be a matter of contention in the U.S. with many tribes attempting to assert their original claims to various lands. In some areas American Indian populations were reduced by foreign diseases contracted through contact with European settlers, and US settlers acquired those emptied lands. In other instances American Indians were removed from their traditional lands by force. Though some would say the U.S. was not a colonial power until the Spanish-American War when it acquired Puerto Rico, Guam and the Philippines, the dominion exercised over land in North America the United States claimed is essentially colonial. The Philippines became independent in 1946. During this period, the nation also became an industrial power. This continued into the 20th century, which has been termed "the American Century" because of the nation's overriding influence on the world. The US became a center for innovation and technological development; major technologies that America either developed or was greatly involved in improving include the telephone, television, computer, the Internet, nuclear weapons, nuclear power, aviation, and aeronautics. In addition to the Civil War, another major traumatic experience for the nation was the Great Depression (1929 to 1939). The nation has also taken part in several major foreign wars, including World War I and World War II (in both of which the US later joined the Allies). During the Cold War, the US was a major player in the Korean War and Vietnam War, and, along with the Soviet Union, was considered one of the world's two "superpowers". With the collapse of the Soviet Union, the US emerged as the world's leading economic and military power. Beginning in the 1990s, the United States became very involved in police actions and peacekeeping, including actions in Kosovo, Haiti, Somalia and Liberia, and the first Persian Gulf War driving Iraq out of Kuwait. After attacks on the World Trade Center and the Pentagon on September 11, 2001, the United States and other allied nations found themselves involved in what has come to be called the "War on Terrorism," which has primarily encompassed military actions in both Afghanistan and Iraq.

Government

Iraq of the United States.]]

Republic and suffrage

The United States is an example of a constitutional republic, with a government composed of and operating through a set of limited powers imposed by its design and enumerated in the United States Constitution. Specifically, the nation operates as a presidential democracy. There are three levels of government: federal, state, and local. Officials of each of these levels are either elected by eligible voters via secret ballot or appointed by other elected officials. Americans enjoy almost universal suffrage from the age of 18 regardless of race, sex, or wealth. There are some limits, however: felons are disenfranchised and in some states former felons are likewise. Furthermore, the national representation of territories and the federal district of Washington, DC in Congress is limited: residents of the District of Columbia are subject to federal laws and federal taxes but their only Congressional representative is a non-voting delegate.

Federal government

The federal government is the national government, comprising the Legislative Branch (led by Congress), the Executive Branch (led by the President), and the Judicial Branch (led by the Supreme Court). These three branches were designed to apply checks and balances on each other. The Constitution limits the powers of the federal government to defense, foreign affairs, the issuing and management of currency, the management of trade and relations between the states, and the protection of human rights. In addition to these explicitly stated powers, the federal government—with the assistance of the Supreme Court—has gradually extended these powers into such areas as welfare and education, on the basis of the "necessary and proper" clause of the Constitution.

The Congress

necessary and proper The Congress of the United States is the legislative branch of the federal government of the United States. It is bicameral, comprising the House of Representatives and the Senate. The House of Representatives consists of 435 members, each of whom represents a congressional district and serves for a two-year term. House seats are apportioned among the states by population; in contrast, each state has two Senators, regardless of population. There are a total of 100 senators, who serve six-year terms. The powers of Congress are limited to those enumerated in the Constitution; all other powers are reserved to the states and the people. The Constitution also includes the necessary-and-proper clause, which grants Congress the power to "make all laws which shall be necessary and proper for carrying into execution the foregoing powers."

The President

necessary-and-proper clause At the top level of the executive branch is the President of the United States. The President and Vice-President are elected as 'running mates' for four-year terms by the Electoral College, for which each state, as well as the District of Columbia, is allocated a number of seats based on its representation (or ostensible representation, in the case of D. C.) in both houses of Congress (see U.S. Electoral College). The relationship between the President and the Congress reflects that between the English monarchy and parliament at the time of the framing of the United States Constitution. Congress can legislate to constrain the President's executive power, even with respect to his or her command of the armed forces; however, this power is used only very rarely—a notable example was the constraint placed on President Richard Nixon's strategy of bombing Cambodia during the Vietnam War. The President cannot directly propose legislation, and must rely on supporters in Congress to promote his or her legislative agenda. The President's signature is required to turn congressional bills into law; in this respect, the President has the power—only occasionally used—to veto congressional legislation. Congress can override a presidential veto with a two-thirds majority vote in both houses. The ultimate power of Congress over the President is that of impeachment or removal of the elected President through a House vote, a Senate trial, and a Senate vote. The threat of using this power has had major political ramifications in the cases of Presidents Andrew Johnson, Richard Nixon, and Bill Clinton. The President makes around 2,000 executive appointments, including members of the Cabinet and ambassadors, which must be approved by the Senate; the President can also issue executive orders and pardons, and has other Constitutional duties, among them the requirement to give a State of the Union address to Congress once a year. Although the President's constitutional role may appear to be constrained, in practice, the office carries enormous prestige that typically eclipses the power of Congress: the Presidency has justifiably been referred to as 'the most powerful office in the world'. The Vice President is first in the line of succession, and is the President of the Senate ex officio, with the ability to cast a tie-breaking vote. The members of the President's Cabinet are responsible for administering the various departments of state, including the Department of Defense, the Justice Department, and the State Department. These departments and department heads have considerable regulatory and political power, and it is they who are responsible for executing federal laws and regulations. George W. Bush is the 43rd President, currently serving his second term.

The Courts

George W. Bush The highest court is the Supreme Court, which consists of nine justices. The court deals with federal and constitutional matters, and can declare legislation made at any level of the government as unconstitutional, nullifying the law and creating precedent for future law and decisions. Below the Supreme Court are the courts of appeals, and below them in turn are the district courts, which are the general trial courts for federal law. Separate from, but not entirely independent of, this federal court system are the individual court systems of each state, each dealing with its own laws and having its own judicial rules and procedures. A case may be appealed from a state court to a federal court only if there is a federal question; the supreme court of each state is the final authority on the interpretation of that state's laws and constitution.

State and local governments

supreme court of each state. Note that Alaska and Hawaii are shown at different scales, and that the Aleutian Islands and the uninhabited Northwestern Hawaiian Islands are omitted from this map.]] The state governments have the greatest influence over people's daily lives. Each state has its own written constitution and has different laws. There are sometimes great differences in law and procedure between the different states, concerning issues such as property, crime, health, and education. The highest elected official of each state is the Governor. Each state also has an elected legislature (bicameral in every state except Nebraska), whose members represent the different parts of the state. Of note is the New Hampshire legislature, which is the third-largest legislative body in the English-speaking world, and has one representative for every 3,000 people. Each state maintains its own judiciary, with the lowest level typically being county courts, and culminating in each state supreme court, though sometimes named differently. In some states, supreme and lower court justices are elected by the people; in others, they are appointed, as they are in the federal system. The institutions that are responsible for local government are typically town, city, or county boards, making laws that affect their particular area. These laws concern issues such as traffic, the sale of alcohol, and keeping animals. The highest elected official of a town or city is usually the mayor. In New England, towns operate directly democratically, and in some states, such as Rhode Island and Connecticut, counties have little or no power, existing only as geographic distinctions. In other areas, county governments have more power, such as to collect taxes and maintain law enforcement agencies.

Political divisions

With the Declaration of Independence, the thirteen colonies proclaimed themselves to be nation states modeled after the European states of the time. Although considered as sovereigns initially, under the Articles of Confederation of 1781 they entered into a "Perpetual Union" and created a fully sovereign federal state, delegating certain powers to the national Congress, including the right to engage in diplomatic relations and to levy war, while each retaining their individual sovereignty, freedom and independence. But the national government proved too ineffective, so the administrative structure of the government was vastly reorganized with the United States Constitution of 1789. Under this new union, the continued status of the individual states as sovereign nation states fell into dispute in 1861, as several states attempted to secede from the union; in response, then-President Abraham Lincoln claimed that such secession was illegal, and the result was the American Civil War. Since the Union victory in 1865, the independent status of the individual states has not been broached again by any state, and the status of each state within the union has been deemed by mainstream officials and academics to be settled as being subordinate to the union as a whole. In subsequent years, the number of states grew steadily due to western expansion, the purchase of lands by the national government from other nation states, and the subdivision of existing states, resulting in the current total of 50. The states are generally divided into smaller administrative regions, including counties, cities and townships. The United States–Canadian border is the longest undefended political boundary in the world. The U.S. is divided into three distinct sections:
- the "continental United States," also known as "the Lower 48" and more accurately termed the conterminous, coterminous or contiguous United States
- Alaska, which is physically connected only to Canada
- the archipelago of Hawaii, in the central Pacific Ocean. The United States also holds several other territories, districts, and possessions, notably the federal district of the District of Columbia, which is the nation's capital, and several overseas insular areas, the most significant of which are American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The Palmyra Atoll is the United States' only incorporated territory; it is unorganized and uninhabited. The United States Navy has held a base at a portion of Guantanamo Bay, Cuba, since 1898. The United States government possesses a lease to this land, which only mutual agreement or United States abandonment of the area can terminate. The present Cuban government of Fidel Castro disputes this arrangement, claiming Cuba was not truly sovereign at the time of the signing. The United States argues this point moot because Cuba apparently ratified the lease post-revolution, and with full sovereignty, when it cashed one rent check in accordance with the disputed treaty.

Foreign relations and military

sovereign] The immense military and economic dominance of the United States has made foreign relations an especially important topic in its politics, with considerable concern about the image of the United States throughout the world. Reactions towards the United States by other nationalities are often strong, ranging from uninhibited admiration and mimicking of all things American to anti-Americanism. US foreign policy has swung about several times over the course of its history between the poles of strict isolationism and imperialism and everywhere in between. Three of the nation's four military branches are administered by the Department of Defense: the Army, the Navy (including the Marine Corps), and the Air Force. The Coast Guard falls under the jurisdiction of the Department of Homeland Security in peacetime, but is placed under the Department of the Navy in time of war. The combined United States armed forces consist of 1.4 million active duty personnel, along with several hundred thousand each in the Reserves and the National Guard. Military conscription ended in 1973. The United States Armed forces are considered to be the most powerful military (of any sort) on Earth and their force projection capabilities are unrivaled by any other nation. The 2005 defense budget amounted to $401.7 billion, which is an increase of 4% over 2004 and of 35% since 2001. Over 50% of that number is spent in research & development. (For comparison, in 2004 the European Union (considered as the second-largest military force) had a combined total of 1.6 million troops, and a defense budget of €160 billion, with less than 10% of that being spent on R&D.)

Largest cities

The United States has dozens of major cities, including 11 of the 55 global cities of all types — with three "alpha" global cities: New York City, Los Angeles, and Chicago. The figures expressed below are for populations within city limits. A different ranking is evident when considering U.S. metro area populations, although the top three would be unchanged. Note that some cities not listed (such as Atlanta, Boston, Las Vegas, Miami, Nashville, New Orleans, Seattle, and Washington, D.C.) are still considered important on the basis of other factors and issues, including culture, economics, heritage, and politics. The twenty largest cities, based on the United States Census Bureau's 2004 estimates, are as follows:

Economy

The United States has the largest single-country economy in the world, with a per-capita gross domestic product of $40,100. In this market-oriented economy, private individuals and business firms make most of the decisions, and the federal and state governments buy needed goods and services predominantly in the private marketplace. gross domestic product The largest industry of the U.S. is now service, which employs roughly three quarters of the U.S. work force. The United States has many natural resources, including oil and gas, metals, and such minerals as gold, soda ash, and zinc. In agriculture, the U.S. is a top producer of, among other crops, corn, soy beans, and wheat; the United States is a net exporter of food. The U.S. manufacturing sector produces goods such as, cars, airplanes, steel, and electronics, among many others. Economic activity varies greatly from one part of the country to another, with many industries being largely dependent on a certain city or region; New York City is the center of the American financial, publishing, broadcasting, and advertising industries; Silicon Valley is the country’s primary location for high-technology companies, while Los Angeles is the most important center for film production. The Midwest is known for its reliance on manufacturing and heavy industry, with Detroit, Michigan, serving as the center of the American automotive industry; the Great Plains are known as the "breadbasket" of America for their tremendous agricultural output; the intermountain region serves as a mining hub and natural gas resource; the Pacific Northwest for fish and timber, while Texas is largely associated with the oil industry; the Southeast is a major hub for both medical research and the textiles industry. Several countries continue to link their currency to the dollar or even use it as a currency (such as Ecuador), although this practice has subsided since the collapse of the Bretton Woods system. Many markets are also quoted in dollars, such as those of oil and gold. The dollar is also the predominant reserve currency in the world, and more than half of global reserves are in dollars. The largest trading partner of the United States is Canada (19%), followed by China (12%), Mexico (11%), and Japan (8%). More than 50% of total trade is with these four countries. In 2003, the United States was ranked as the third most visited tourist destination in the world; its 40,400,000 visitors ranked behind France's 75,000,000 and Spain's 52,500,000. Labor unions have existed since the 19th century, and grew large and powerful from the 1930s to the 1950s. See Labor history of the United States. Since 1970 they have shrunk in the private sector and now cover fewer than 8% of the workers. However union membership has grown rapidly in the public sector, especially among teachers, nurses, police, postal workers, and municipal clerks. There have been few strikes in recent years. The United States' imports exceed exports by 80%, leading to an annual trade deficit of $700,000,000,000, or 6% of gross domestic product. It is the largest debtor nation in the world, with total gross foreign debt of over $13,000,000,000,000 (2005 estimate); and it absorbs more than 50% of global savings annually. Since the 1980s, the U.S. has increased the use of neoliberal economic policies that reduce government intervention and reduce the size of the welfare state, backing away from the more interventionist Keynsian economic policies that had been in favor since the Great Depression. As a result, the United States provides fewer government-delivered social welfare services than most industrialized nations, choosing instead to keep its tax burden lower and relying more heavily on the free market and private charities. Sixteen states and the District of Columbia have minimum wages higher than the national level ($5.15 per-hour), including the highest, Washington State at $7.35. Twenty-six states are the same as the federal level; two--Ohio and Kansas--are below; and six do not have state laws. America's wealth is relatively highly concentrated. The average C.E.O. earns 500 times the typical amount a worker grosses, this is up from 25 times in the late 1970s. In terms of wealth the top 1% of Americans own 40% of all assets and 50.1% of the country's income goes to the top twenty percent of households. Average wages for the majority of employees have been largely stagnating since the 1970s. America's poverty line defined as a family of four earning less than $19,157 is at 12.7% of the general population. Approximately one out of every five children in the United States grows up below the official poverty line. Among racial groups; African Americans have the lowest median income while Asians had the highest. Regionally, the southern states had the lowest median incomes while the West Coast and New England had the highest. The current Federal Reserve Chairman Alan Greenspan remarked that the U.S.’s growing income inequality since the 1970s is, "not the type of thing which a democratic society - a capitalist democratic society - can really accept without addressing."[http://www.csmonitor.com/2005/0614/p01s03-usec.html?s=itm] However, Greenspan also noted, "...you can look at the system and say it's got a lot of problems to it, and sure it does. It always has. But you can't get around the fact that this is the most extraordinarily successful economy in history."

Transportation

Alan Greenspan ]] Because the United States is a relatively young nation, most of the development of U.S. cities has taken place since the invention of the automobile. To link its vast territory, the United States built a network of high-capacity, high-speed highways, of which the most important element is the Interstate Highway system, commissioned in the 1950s by President Dwight D. Eisenhower and modeled after the German Autobahn. The United States also has a transcontinental rail system, which is used for moving freight across the lower forty-eight states. Passenger rail service is provided by Amtrak, which serves forty-six of the lower forty-eight states. Many cities in the United States have extensive mass-transit systems. New York City operates one of the world's largest and most heavily used subway systems. The regional rail and bus networks that extend into Long Island, New Jersey, Upstate New York, and Connecticut are among the most heavily used in the world. Air travel is often preferred for destinations over 300 miles (500 kilometers) away. In terms of passengers, seventeen of the world's thirty busiest airports in 2004 were in the U.S., including the world's busiest, Hartsfield-Jackson Atlanta International Airport; in terms of cargo, in the same year, twelve of the world's thirty busiest airports were in the U.S., including the world's busiest, Memphis International Airport. There are several major seaports in the United States; the three busiest are the Port of Los Angeles, California; the Port of Long Beach, California; and the Port of New York and New Jersey. Others include Houston, Texas; Charleston, South Carolina; Savannah, Georgia; Miami, Florida; Portland, Oregon; San Francisco, California; Boston, Massachusetts; Philadelphia, Pennsylvania; and Seattle, Washington; plus, outside the contiguous forty-eight states, Anchorage, Alaska, and Honolulu, Hawaii.

Demographics

Hawaii The mean center of the U.S. population continues to drift farther west and south. The fastest growing region is the western United States followed by the southern portion. According to Census 2000, the states that saw the greatest increases from 1990 were: Nevada (66.3%), Arizona (40%), Colorado (30.6%), Utah (29.6%), Idaho (28.5%), Georgia (26.4%), Florida (23.5%), Texas (22.8%), North Carolina (21.4%), and Washington (21.1%). [http://www.census.gov/population/cen2000/phc-t2/tab03.pdf]

Ethnicity and race

:Main article: Racial demographics of the United States The United States is a very racially diverse country. According to the 2000 census, it has 31 ethnic groups with at least one million members each, and numerous others represented in smaller amounts. The majority of Americans descend from white European immigrants who arrived at the establishment of the first colonies (most after Reconstruction). This majority--69.1% in 2000--decreases each year, and is expected to become a plurality within a few decades. The most frequently stated European ancestries are German (15.2%), Irish (10.8%), English (8.7%), Italian (5.6%) and Scandinavian (3.7%). Many immigrants also hail from Slavic countries such as Poland and Russia. Other significant immigrant populations came from eastern and southern Europe and French Canada. Russia Hispanics from Mexico and South and Central America are the largest minority group in the country, comprising 12.5% of the population (2000 census). People of Mexican descent made up 7.3% of the population in the 2000 census, and this proportion is expected to increase significantly in the coming decades. About 12.3% (2000 census) of the American people are African Americans (Blacks). African Americans are spread throughout the country, but their presence is largest in the South. Asian Americans--including Native Hawaiians and Pacific Islanders--are a third significant minority (3.7% of the population in 2000). Most Asian Americans are concentrated on the West Coast and Hawaii. The largest groups are immigrants or descendants of emigrants from the Philippines, China, India, Vietnam, South Korea, and Japan. Indigenous peoples in the United States, such as American Indians and Inuit, make up 0.9% of the population (2000 census). About 35% live on Indian reservations.

Religion

Polls estimate that just under 80 percent of Americans are Christians of various denominations. The other 20 percent comprises other religions such as Hinduism, Judaism, Islam, and Buddhism, other various faiths, and those without a specific religion. The United States is noteworthy among developed nations for its relatively high level of religiosity. According to a 2004 Gallup poll, about 44% of Americans attend a religious service at least once a week. However, this rate is not uniform across the country; attendance is more common in the Bible Belt—composed largely of Southern and Midwestern states—than in the Northeast and West Coast. In the Southern states, Baptists are the largest group, followed by Methodists; Roman Catholics are dominant in the Northeast and in large parts of the Midwest due to their being settled by descendants of Catholic immigrants from Europe (such as Germany, Ireland, Italy, and Poland) or other parts of North America (mainly Quebec and Puerto Rico). The rest of the country for the most part has a complex mixture of various Christian groups.

Education

West Coast's home at Monticello and the University of Virginia (library building shown above, and designed by Jefferson), the only collegiate campus on the list. Both sites are located in Charlottesville, Virginia.]] In the United States, education is a state, not federal, responsibility, and the laws and standards vary considerably. However, the federal government, through the Department of Education, is involved with funding of some programs and exerts some influence through its ability to control funding. In most states, all students must attend mandatory schooling starting with kindergarten, which children normally enter at age 5, and following through 12th grade, which is normally completed at age 18

Canada

Canada is the second largest country in the world in terms of area, extending from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean with claims extending to the North Pole. The northern-most country on the mainland of North America, Canada has land borders only with the United States. Governed as a parliamentary democracy and constitutional monarchy, Canada is a federation of ten provinces with three territories. Initially constituted in 1867, the country's constitution was patriated in 1982 from the United Kingdom. Canada's head of state is its monarch, currently Queen Elizabeth II, who is represented in Canada by the Governor General, presently Michaëlle Jean. The head of government is the Prime Minister, currently Paul Martin; his minority government recently lost a vote of non-confidence in the Canadian House of Commons and asked for the dissolution of the Parliament by the Governor General, who then issued a Royal proclamation authorising the issue of election writs, and stating a federal election will take place on 2006 January 23. Canada's official languages are English and French. As of 2005, its official population estimate is approximately 32.4 million ^{[http://www.statcan.ca/english/edu/clock/population.htm]}.

Overview

The capital city is Ottawa, Ontario, the seat of Canada's Parliament. The Governor General, the Prime Minister, the Leader of the Loyal Opposition, and the Speaker of the House of Commons have official residences in the National Capital Region.National Capital Region, Ontario.]] Originally a union of British colonies with significant French influence and entitled as a "dominion", Canada is a founding member of the United Nations, the Commonwealth of Nations, and La Francophonie. Canada defines itself as a bilingual and multicultural nation:
- English is the official (and majority) language in most provinces of Canada.
- French is the official language of Quebec, an official language of New Brunswick, and is spoken in various areas throughout the country.
- Several Aboriginal languages have official status in the Northwest Territories; Inuktitut is the majority language in Nunavut and has official status there. Canada is a technologically advanced and industrialized nation. It is a net exporter of energy because of its large fossil fuel deposits, nuclear energy generation, and hydroelectric power capacity. Its diversified economy relies heavily on an abundance of natural resources and trade, particularly with the United States, with which it has had a long and complex relationship. Canada has ten provinces and three territories: Canada's major cities that are not capital cities include Montreal, Quebec; Vancouver, British Columbia; and Calgary, Alberta.

Canada's name

The name Canada is believed to come from the Huron-Iroquois word kanata, which means "village" or "settlement". In 1535, locals used the word to tell Jacques Cartier the way to Stadacona, site of present-day Quebec City. Cartier used Canada to refer not only to Stadacona, but also to the entire area subject to Donnacona, Chief at Stadacona; by 1547, maps began referring to this and the surrounding area as Canada.

History

Aboriginal tradition holds that the First Peoples have inhabited parts of what is now called Canada since the dawn of time. Archaeological records show that these lands have been inhabited for at least 10,000 years. Several Viking expeditions occurred circa AD 1000, with evidence of settlement at L'Anse aux Meadows. British claims to North America date from 1497, when John Cabot reached what he called Newfoundland, though it is unclear whether Cabot landed in current Newfoundland, Nova Scotia, or Maine. French claims date from explorations by Jacques Cartier (from 1534) and Samuel de Champlain (from 1603). Neither Cabot's nor Cartier's explorations left any permanent settlers behind. On August 5, 1583, Sir Humphrey Gilbert claimed Newfoundland as England's first overseas colony under Royal Charter of Queen Elizabeth I. In 1604, French settlers were the first Europeans to settle permanently in what is now Canada. After an unsuccessful winter in St. Croix Island (today in Maine), they settled Port-Royal in what is now the Annapolis Valley in Nova Scotia, but moved to found Quebec City in 1608. The current Acadians are descendants of settlers who came later in the same century and re-founded Port-Royal. New France was generally the name given to the French colonies of Canada and Acadia (and later Louisiana).Louisiana, depicts British General Wolfe's final moments during the Battle of the Plains of Abraham in 1759.]] British settlements were established along the Atlantic seaboard and around Hudson Bay. As these colonies expanded, a struggle for control of North America took place between 1689 and 1763 (see French and Indian Wars), exacerbated by wars in Europe between France and Great Britain. France progressively lost territory to Great Britain, surrendering peninsular Nova Scotia in the 1713 Treaty of Utrecht and the remainder of New France including what was left of Acadia in the Treaty of Paris (1763). During and after the American Revolution approximately 70,000 [http://www.uelac.org/whatis.html] Loyalists fled the Thirteen Colonies. Of these, roughly 50,000 United Empire Loyalists [http://www.infoplease.com/ce6/history/A0850061.html] settled in the British North American colonies which then consisted of Newfoundland, Nova Scotia, the Province of Quebec, and Prince Edward Island (created 1769). To accommodate the Loyalists, Britain created the colony of New Brunswick in 1784 from part of Nova Scotia, and divided Quebec into Lower Canada and Upper Canada under the Constitutional Act of
