Australia

The Commonwealth of Australia is a country in the Southern Hemisphere comprising the world's smallest continent and a number of islands in the Southern, Indian and Pacific Oceans. Australia's neighbouring countries are Indonesia, East Timor and Papua New Guinea to the north, the Solomon Islands, Vanuatu and New Caledonia to the northeast, and New Zealand to the southeast. The continent of Australia has been inhabited for over 40,000 years by Indigenous Australians. After sporadic visits by fishermen from the north and by European explorers and merchants starting in the 17th century, the eastern half of the continent was claimed by the British in 1770 and officially settled as the penal colony of New South Wales on 26 January 1788. As the population grew and new areas were explored, another five largely self-governing Crown Colonies were successively established over the course of the 19th century. On 1 January 1901, the six colonies federated and the Commonwealth of Australia was formed. Since federation, Australia has maintained a stable liberal democratic political system and remains a Commonwealth Realm. The current population of around 20.4 million is concentrated mainly in the large coastal cities of Sydney, Melbourne, Brisbane, Perth and Adelaide.

Origin and history of the name

The name Australia is derived from the Latin australis, meaning southern. Legends of an "unknown southern land" (terra australis incognita) date back to the Roman times and were commonplace in mediæval geography, but they were not based on any actual knowledge of the continent. The Dutch adjectival form Australische ("Australian," in the sense of "southern") was used by Dutch officials in Batavia to refer to the newly discovered land to the south as early as 1638. The first English language writer to use the word "Australia" was Alexander Dalrymple in An Historical Collection of Voyages and Discoveries in the South Pacific Ocean, published in 1771. He used the term to refer to the entire South Pacific region, not specifically to the Australian continent. In 1793, George Shaw and Sir James Smith published Zoology and Botany of New Holland, in which they wrote of "the vast island, or rather continent, of Australia, Australasia or New Holland." New Holland was established on this site.]] The name "Australia" was popularised by the 1814 work A Voyage to Terra Australis by the navigator Matthew Flinders. Despite its title, which reflected the view of the Admiralty, Flinders used the word "Australia" in the book, which was widely read and gave the term general currency. Governor Lachlan Macquarie of New South Wales subsequently used the word in his dispatches to England. In 1817 he recommended that it be officially adopted. In 1824, the British Admiralty agreed that the continent should be known officially as Australia.

History

England, claiming the land for Britain in 1770. This replica was built in Fremantle in 1988 for Australia's bicentenary.]] The first human habitation of Australia is estimated to have occurred between 42,000 and 48,000 years ago. The first Australians were the ancestors of the current Indigenous Australians; they arrived via land bridges and short sea-crossings from present-day India or Southeast Asia. Most of these people were hunter-gatherers, with a complex oral culture and spiritual values based on reverence for the land and a belief in the Dreamtime. The Torres Strait Islanders, ethnically Melanesian, inhabited the Torres Strait Islands and parts of far-north Queensland; they possess distinct cultural practices and practised subsistence agriculture. The first undisputed recorded European sighting of the Australian continent was made by the Dutch navigator Willem Jansz, who sighted the coast of Cape York Peninsula in 1606. During the 17th century, the Dutch charted the whole of the western and northern coastlines of what they called New Holland, but made no attempt at settlement. In 1770, James Cook sailed along and mapped the east coast of Australia, which he named New South Wales and claimed for Britain. The expedition's discoveries provided impetus for the establishment of a penal colony there following the loss of the American colonies that had previously filled that role. penal colony was Australia's largest penal colony.]] The British Crown Colony of New South Wales started with the establishment of a settlement at Port Jackson by Captain Arthur Phillip on 26 January 1788. This date was later to become Australia's national day, Australia Day. Van Diemen's Land, now known as Tasmania, was settled in 1803 and became a separate colony in 1825. Britain formally claimed the western part of Australia in 1829. Separate colonies were created from parts of New South Wales: South Australia in 1836, Victoria in 1851, and Queensland in 1859. The Northern Territory (NT) was founded in 1863 as part of the Province of South Australia. Victoria and South Australia were founded as "free colonies"—that is, they were never penal colonies, although the former did receive some convicts from Tasmania. Western Australia was also founded "free", but later accepted transported convicts due to an acute labour shortage. The transportation of convicts to Australia was phased out between 1840 and 1868. The Indigenous Australian population, estimated at about 350,000 at the time of European settlement, declined steeply for 150 years following settlement, mainly because of infectious disease, and forced migration, the removal of children and other colonial government policies, that some historians and Indigenous Australians have argued could be considered to constitute genocide by today's understanding. Such interpretations of Aboriginal history are disputed by some as being exaggerated or fabricated for political or ideological reasons. Following the 1967 referendum, the Federal government gained the power to implement policies and make laws with respect to Aborigines. Traditional ownership of land—native title—was not recognised until the High Court case Mabo v Queensland (No 2) overturned the notion of Australia as terra nullius at the time of European occupation. terra nullius ceremony in Port Melbourne, Victoria, 25 April 2005. Ceremonies such as this are held in virtually every suburb and town in Australia.]] A gold rush began in Australia in the early 1850s, and the Eureka Stockade rebellion in 1854 was an early expression of nationalist sentiment. Between 1855 and 1890, the six colonies individually gained responsible government, managing most of their own affairs while remaining part of the British Empire. The Colonial Office in London retained control of some matters, notably foreign affairs, defence and international shipping. On 1 January 1901, federation of the colonies was achieved after a decade of planning, consultation and voting, and the Commonwealth of Australia was born, as a Dominion of the British Empire. The Australian Capital Territory (ACT) was formed from New South Wales in 1911 to provide a location for the proposed new federal capital of Canberra (Melbourne was the capital from 1901 to 1927). The Northern Territory was transferred from the control of the South Australian government to the Commonwealth in 1911. Australia willingly participated in World War I; many Australians regard the defeat of the Australian and New Zealand Army Corps (ANZACs) at Gallipoli as the birth of the nation—its first major military action. Much like Gallipoli the Kokoda Track Campaign is regarded by many as a nation defining battle from World War II. The Statute of Westminster 1931 formally ended most of the constitutional links between Australia and Britain, but Australia did not adopt the Statute until 1942. The shock of Britain's defeat in Asia in 1942 and the threat of Japanese invasion caused Australia to turn to the United States as a new ally and protector. Since 1951, Australia has been a formal military ally of the US under the auspices of the ANZUS treaty. After World War II, Australia encouraged mass immigration from Europe; since the 1970s and the abolition of the White Australia policy, immigration from Asia and other parts of the world was also encouraged. As a result, Australia's demography, culture and image of itself were radically transformed. The final constitutional ties between Australia and Britain ended in 1986 with the passing of the Australia Act 1986, ending any British role in the Australian States, and ending judicial appeals to the UK Privy Council. Although Australian voters rejected a move to become a republic in 1999 by a 55% majority, Australia's links to its British past are increasingly tenuous. Since the election of the Whitlam Government in 1972, there has been an increasing focus on the nation's future as a part of the Asia-Pacific region.

Politics

Whitlam Government was opened in 1988 replacing the provisional Parliament House building opened in 1927.]] The Commonwealth of Australia is a constitutional monarchy and has a parliamentary system of government. Queen Elizabeth II is the Queen of Australia, a role that is distinct from her position as Elizabeth II of the United Kingdom. The Queen is nominally represented by the Governor-General; although the Constitution gives extensive executive powers to the Governor-General, these are normally exercised only on the advice of the Prime Minister. The most notable exercise of the Governor-General's reserve powers outside the Prime Minister's direction was the dismissal of the Whitlam Government in the constitutional crisis of 1975. There are three branches of government.
- The legislature: the Commonwealth Parliament, comprising the Queen, the Senate (the Red house), and the House of Representatives (the Green house); the Queen is represented by the Governor-General, who in practice exercises little or no power over the Parliament.
- The executive: the Federal Executive Council (the Governor-General as advised by the executive councillors); in practice, the councillors are the prime minister and ministers of state, whose advice the Governor-General accepts, with rare exceptions.
- The judiciary: the High Court of Australia and other federal courts. The State courts became formally independent from the Judicial Committee of the Privy Council when the Australia Act was passed in 1986. The bicameral Commonwealth Parliament consists of the Queen, the Senate (the upper house) of 76 senators, and a House of Representatives (the lower house) of 150 members. Members of the lower house are elected from single-member constituencies, commonly known as 'electorates' or 'seats'. Seats in the House of Representatives are allocated to states on the basis of population. In the Senate, each state, regardless of population, is represented by 12 senators, with the ACT and the NT each electing two. Elections for both chambers are held every three years; typically only half of the Senate seats are put to each election, because senators have overlapping six-year terms. The party with majority support in the House of Representatives forms Government, with its leader becoming Prime Minister. There are three major political parties: the Labor Party, the Liberal Party and the National Party. Independent members and several minor parties—including the Greens, Family First and the Australian Democrats—have achieved representation in Australian parliaments, mostly in upper houses, although their influence has been marginal. Since the 1996 election, the Liberal/National Coalition led by the Prime Minister, John Howard, has been in power in Canberra. In the 2004 election, the Coalition won control of the Senate, the first time that a party (or coalition of governing parties) has done so while in government in more than 20 years. The Labor Party is in power in every state and territory. Voting is compulsory in each state and territory and at the federal level.

States and territories

Voting is compulsory Australia consists of six states, two major mainland territories, and other minor territories. The states are New South Wales, Queensland, South Australia, Tasmania, Victoria and Western Australia. The two major mainland territories are the Northern Territory and the Australian Capital Territory. In most respects, the territories function similarly to the states, but the Commonwealth Parliament can override any legislation of their parliaments. By contrast, federal legislation overrides state legislation only with respect to certain areas as set out in Section 51 of the Constitution; all residual legislative powers are retained by the state parliaments, including powers over hospitals, education, police, the judiciary, roads, public transport and local government. Each state and territory has its own legislature (unicameral in the case of the Northern Territory, the ACT and Queensland, and bicameral in the remaining states). The lower house is known as the Legislative Assembly (House of Assembly in South Australia and Tasmania) and the upper house the Legislative Council. The heads of the governments in each state and territory are called premiers and chief ministers, respectively. The Queen is represented in each state by a governor; an administrator in the Northern Territory, and the Governor-General in the ACT, have analogous roles. Australia also has several minor territories; the federal government administers a separate area within New South Wales, the Jervis Bay Territory, as a naval base and sea port for the national capital. In addition Australia has the following, inhabited, external territories: Norfolk Island, Christmas Island, Cocos (Keeling) Islands, and several largely uninhabited external territories: Ashmore and Cartier Islands, Coral Sea Islands, Heard Island and McDonald Islands and the Australian Antarctic Territory.

Foreign relations and military

Over recent decades, Australia's foreign relations have been driven by a close association with the United States, through the ANZUS pact and by a desire to develop relationships with Asia and the Pacific, particularly through ASEAN and the Pacific Islands Forum. In 2005 Australia secured an inaugural seat at the East Asia Summit following its accession to the Treaty of Amity and Cooperation. Australia is a member of the Commonwealth of Nations, in which the Commonwealth Heads of Government meetings provide the main forum for co-operation. Much of Australia's diplomatic energy is focused on international trade liberalisation. Australia led the formation of the Cairns Group and APEC, and is a member of the OECD and the WTO. Australia has pursued several major bilateral free trade agreements, most recently the US–Australia Free Trade Agreement. Australia is a founding member of the United Nations, and maintains an international aid program under which some 60 countries receive assistance. The 2005–06 budget provides A$2.5bn for development assistance; as a percentage of GDP, this contribution is less than that of the UN Millennium Development Goals. Australia's armed forces—the Australian Defence Force (ADF)—comprise the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF). All branches of the ADF have been involved in UN and regional peacekeeping (most recently in East Timor, the Solomon Islands and Sudan), disaster relief, and armed conflict, including the 2003 Invasion of Iraq. The government appoints the chief of the Defence Force from one of the armed services; the current chief is Air Chief Marshal Angus Houston. In 2005–06, the defence budget is A$17.5bn.

Geography and climate

Angus Houston Australia's 7,686,850 km² (2,967,909 mi²) landmass is on the Indo-Australian Plate. Surrounded by the Indian, Southern and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas. Australia has a total 25,760 km (16,007 mi) of coastline and claims an extensive Exclusive Economic Zone of 8,148,250 km² or 3,146,057 mi² (excluding the Australian Antarctic Territory). Climate is highly influenced by ocean currents, including the El Niño southern oscillation, which is correlated with periodic drought, and the seasonal tropical low pressure system that produces cyclones in northern Australia. By far the largest part of Australia is desert or semi-arid. Australia is the driest inhabited continent, the flattest, and has the oldest and least fertile soils. Only the south-east and south-west corners of the continent have a temperate climate. The northern part of the country, with a tropical climate, has a vegetation consisting of rainforest, woodland, grassland and desert. The Great Barrier Reef, the world's largest coral reef, lies a short distance off the north-east coast and extends for over 2,000 km (1,250 mi). The world's two largest monoliths are located in Australia, Mount Augustus in Western Australia is the largest and Uluru in central Australia is the second largest. At 2,228 m (7,310 ft), Mount Kosciuszko on the Great Dividing Range is the highest mountain on the Australian mainland, although Mawson Peak on the remote Australian territory of Heard Island is taller at 2,745 m (9,006 ft).

Flora and fauna

Heard Island of the wallaby is currently being sequenced; when the sequencing is completed, it will be a major contribution to marsupial biology.]] Although most of Australia is semi-arid or desert, it covers a diverse range of habitats, from alpine heaths to tropical rainforests. Because of the great age and consequent low levels of fertility of the continent, its extremely variable weather patterns, and its long-term geographic isolation, much of Australia's biota is unique and diverse. About 85% of flowering plants, 84% of mammals, more than 45% of birds, and 89% of in-shore, temperate-zone fish are endemic. Many of Australia's ecoregions, and the species within those regions, are threatened by human activities and introduced plant and animal species. The federal Environment Protection and Biodiversity Conservation Act 1999 is a legal framework used for the protection of threatened species. Numerous protected areas have been created to protect and preserve Australia's unique ecosystems, 64 wetlands are registered under the Ramsar Convention, and 16 World Heritage Sites have been established. Australia was ranked 13th in the World on the 2005 Environmental Sustainability Index. Environmental Sustainability Index.]] Most Australian plant species are evergreen and many are adapted to fire and drought, including the eucalypts and acacias. Australia has a rich variety of endemic legume species that thrive in nutrient-poor soils because of their symbiosis with Rhizobia bacteria and mycorrhizal fungi. Well-known Australian fauna include monotremes (the platypus and echidna), and a host of marsupials, including the koala, kangaroo, wombat, and birds such as the emu, cockatoo, and kookaburra. The dingo was introduced by Austronesian people that traded with Indigenous Australians around 4000 BCE. Many plant and animal species became extinct soon after human settlement, including the Australian megafauna; many more have become extinct since European settlement, among them the Thylacine (Tasmanian Tiger).

Economy

Thylacine Australia has a prosperous, Western-style mixed economy, with a per capita GDP slightly higher than those of the UK, Germany and France. The country was ranked third in the United Nations' 2005 Human Development Index and sixth in The Economist worldwide quality-of-life index 2005. In recent years, the Australian economy has been resilient in the face of global economic downturn. Rising output in the domestic economy has been offsetting the global slump, and business and consumer confidence remains robust. Australia's emphasis on reform is another key factor behind the economy's strength. In the 1980s, the Labor Party, led by Prime Minister Bob Hawke and Treasurer Paul Keating, started the process of modernising the Australian economy by floating the Australian dollar in 1983, and deregulating the financial system. Since 1996, the Howard government has continued the process of micro-economic reform, including the partial deregulation of the labour market and the privatisation of state-owned businesses, most notably in the telecommunications industry. Substantial reform of the indirect tax system was achieved in July 2000 with the introduction of a 10% Goods and Services Tax, which has slightly reduced the heavy reliance on personal and company income tax that still characterises Australia's tax system. The Australian economy has not suffered a recession since the early 1990s. As of July 2005, unemployment was 5.0% with 10,030,300 persons employed. The service sector of the economy, including tourism, education, and financial services, comprises 69% of GDP. Agriculture and natural-resources represent only 3% and 5% of GDP, respectively, but contribute substantially to Australia's export performance. Australia's largest export markets include Japan, China, the United States, South Korea and New Zealand. Areas of concern to some economists include the chronically high current account deficit and also high levels of net foreign debt.

Demographics

current account deficit Most of the estimated 20.4 million Australians are descended from 19th- and 20th-century immigrants, the majority from Britain and Ireland. Australia's population has quadrupled since the end of World War I , spurred by an ambitious immigration program. In 2001, the five largest groups of the 27.4% of Australians who were born overseas were from the United Kingdom, New Zealand, Italy, Vietnam and China. Following the abolition of the White Australia policy, numerous government initiatives have been established to encourage and promote racial harmony based on a policy of multiculturalism. Australia’s population has increased by about 60 times since European settlement. The self-declared indigenous population—including Torres Strait Islanders, who are of Melanesian descent—was 410,003 (2.2% of the total population) in 2001, a significant increase from the 1977 census, which showed an indigenous population of 115,953. Indigenous Australians have higher rates of imprisonment and unemployment, lower levels of education and life expectancies for males and females that are 17 years lower than those of other Australians. Perceived racial inequality is an ongoing political and human rights issue for Australians. human rights.]] In common with many other developed countries, Australia is experiencing a demographic shift towards an older population, with more retirees and fewer people of working age. A large number of Australians (759,849 for the period 2002–03) live outside their home country. Australia has maintained one of the most active immigration programs in the world to boost population growth. Most immigrants are skilled; the quota includes categories for family members and refugees. English is the official language, and is spoken and written in a distinct variety known as Australian English. According to the 2001 census, English is the only language spoken in the home for around 80% of the population. The next most common languages spoken at home are Chinese (2.1%), Italian (1.9%) and Greek (1.4%). A considerable proportion of first- and second-generation migrants are bilingual. It is believed that there were between 200 and 300 Australian Aboriginal languages at the time of first European contact. Only about 70 of these languages have survived, and all but 20 of these are now endangered. An indigenous language remains the main language for about 50,000 (0.02%) people. Australia has a sign language known as Auslan, which is the main language of about 6,500 deaf people. The Australian Constitution guarantees the separation of church and state; there is no state religion. The 2001 census identified that 68% of Australians call themselves Christian: 27% identifying themselves as Roman Catholic and 21% as Anglican. Five per cent of Australians identify themselves as followers of non-Christian religions, and 26% as non-religious. Like many Western countries, the level of active participation in church worship is much lower than this; weekly attendance at church services is about 1.5 million, about 7.5% of the population. School attendance is compulsory throughout Australia between the ages of 6–15 years (16 years in South Australia and Tasmania), contributing to an adult literacy rate that is assumed to be 99%. Government grants have supported the establishment of Australia's 38 universities, and although several private universities have been established, the majority receive government funding. There is a state-based system of vocational training colleges, known as TAFE Institutes, and many trades conduct apprenticeships for training new tradespeople. Approximately 58% of Australians between the ages of 25 and 64 have vocational or tertiary qualifications.

Culture

apprenticeship.]] The primary basis of Australian culture up until the mid-20th century was Anglo-Celtic, although distinctive Australian features had been evolving from the environment and indigenous culture. Over the past 50 years, Australian culture has been strongly influenced by American popular culture (particularly television and cinema), large-scale immigration from non-English-speaking countries, and Australia's Asian neighbours. Australia has a long history of visual arts, starting with the cave and bark paintings of its indigenous peoples. From the time of European settlement, a common theme in Australian art has been the Australian landscape, seen in the works of Arthur Streeton, Arthur Boyd and Albert Namatjira, among others. The traditions of indigenous Australians are largely transmitted orally and are closely tied to ceremony and the telling of the stories of the Dreamtime. Australian Aboriginal music, dance and art have a palpable influence on contemporary Australian visual and performing arts. Australia has an active tradition of music, ballet and theatre; many of its performing arts companies receive public funding through the federal government's Australia Council. There is a symphony orchestra in each capital city, and a national opera company, Opera Australia, first made prominent by the renowned diva Dame Joan Sutherland; Australian music includes classical, jazz, and many popular music genres. Australian literature has also been influenced by the landscape; the works of writers such as Banjo Paterson and Henry Lawson captured the experience of the Australian bush. The character of colonial Australia, as embodied in early literature, resonates with modern Australia and its perceived emphasis on egalitarianism, mateship, and anti-authoritarianism. In 1973, Patrick White was awarded the Nobel Prize in Literature, the only Australian to have achieved this; he is recognised as one of the great English-language writers of the 20th century. Australian English is a major variety of the language; its grammar and spelling are largely based on those of British English, overlaid with a rich vernacular of unique lexical items and phrases, some of which have found their way into standard English. Australia has two public broadcasters (the ABC and SBS), three commercial television networks, three pay TV services, and numerous public, non-profit television and radio stations. Australia's film industry has achieved critical and commercial successes. Each major city has daily newspapers, and there are two national daily newspapers, The Australian and The Australian Financial Review. According to Reporters Without Borders in 2005, Australia is in 31st position on a list of countries ranked by press freedom, behind New Zealand (9th) and the United Kingdom (28th) but ahead of the United States. This ranking is primarily due to the limited diversity of commercial media ownership in Australia. Most Australian print media in particular is under the control of either News Corporation or John Fairfax Holdings. John Fairfax Holdings Sport is an important part of Australian culture, assisted by a climate that favours outdoor activities; 23.5% Australians over the age of 15 regularly participate in organised sporting activities. At an international level, Australia has particularly strong teams in cricket, field hockey, netball, rugby league, rugby union, and performs well in cycling and swimming. Australia has participated in every summer Olympic Games of the modern era, and every Commonwealth Games. Australia has hosted the 1956 and 2000 Summer Olympics, and has ranked among the top five medal-takers since 2000. It has also hosted the 1938, 1962 and 1982 Commonwealth Games, and will host the 2006 Commonwealth Games in Melbourne. Australian rules football is one of the most popular national sports, albeit it, one that is only played in Australia; players gain some international prominence through International Rules which is an annual meeting between the Australian code and Irish Gaelic Football. Corporate and government sponsorship of many sports and élite athletes is common in Australia. Televised sport is popular; some of the highest rating television programs include the summer Olympic Games and the grand finals of local and international football competitions.

Continent

shows land mass with minimal distortion as only one continuous continent]] A continent (Latin continere, "to hold together") is a large continuous land mass. There are several conceptions of what a continent is, geographic, geologic, and tectonic.

Geographic continents

Because geography is defined by local convention, there are several conceptions as to which landmasses qualify as continents. There are names for six, but America is often divided, and Europe is often united with Asia. Ignoring cases where Antarctica is omitted, there are half a dozen lists. tectonic The 7-continent model is usually taught in Western Europe, the United States, Australia, and much of Asia. In Canada, the government-approved [http://atlas.gc.ca/site/english/maps/reference/international/world/referencemap_image_view Atlas of Canada] names 7 continents and teaches Oceania instead of Australia. The 6-continent combined-America model is taught in Iran, and Latin America. The 6-continent Eurasia model is preferred by the scientific community, and as such is commonly found in all parts of the world, but is especially used in Russia and other countries of Eastern Europe, and in Japan. Historians may use the 5-continent model in which North Africa is separated from Sub-Saharan Africa and attached to Eurasia (Jared Diamond) or the 4-continent Afro-Eurasian model (Andre Gunder Frank). In its original sense, "continent" meant (and still means) mainland. In the Greco-Roman world, there was but one known, the Continent, which we today call the Old World. In the mid 1600s Peter Heylin wrote in his Cosmographie that "A Continent is a great quantity of Land, not separated by any Sea from the rest of the World, as the whole Continent of Europe, Asia, Africa." As late as 1727 Ephraim Chambers wrote in his Cyclopædia, "The world is ordinarily divided into two grand continents: the old and the new." However, since Classical times this Continent was divided into "peninsulas" which also came to be called continents, since they were great land masses themselves. Through the Middle Ages, there were three such continents in the Western conception: Europe, Africa, and Asia. The European discovery of America in 1492 made four; and Australia in 1606 would make five, though not right away: as late as 1813 geographers wrote of Australia as "New Holland, an immense Island, which some geographers dignify with the appellation of another continent". However, dividing America in two was commonplace by this time, and would also produce a fifth continent. The idea of the Five Continents is still strong in Europe and Asia, and is represented by the five rings on the Olympic flag. Antarctica was sighted in 1820, for the sixth and last continent to be given a separate name, though a great "antarctic" (antipodean) landmass had been anticipated for millennia. Dividing the Americas now made seven continents, nicely symmetrical with the magical number of the Seven Seas, Seven Heavens, and the seven heavenly bodies that gave their names to the seven days of the week. However, this division never appealed to Latin America, which saw itself spanning America as a single landmass, and there the conception of six continents remains, as it does in scattered other countries such as Japan. From a modern perspective, the continent with the least reason for separate recognition is Europe, and in scientific circles people generally prefer to subsume Europe and Asia into Eurasia. This appealed to Russia, which spans Eurasia, and in Russia and (at least formerly) in Eastern Europe, Eurasia is or was taught as being one of six continents. Geographers and historians often find it useful to define larger land masses connected by land bridges: # Africa-Eurasia (also called Eurafrasia): the combined land mass of Africa and Eurasia; # America (or the Americas): the combined land mass of North America and South America; # Laurasia: the combined land mass of Eurasia and North America, which were connected by Beringia during the Ice Age; # Sahul: the combined land mass of Australia, New Guinea, and Tasmania during the Ice Age. That is, during the last Ice Age, there were three large landmasses: Africa-Eurasia + America (which has no name), Sahul, and Antarctica. These larger land masses are usually considered supercontinents rather than continents, however. In the last century it has also become conventional to subdivide Eurasia into the regions of Europe, Asia, and the Middle East. America is often divided into the regions of North America, Central America, and South America. Continents are also sometimes subdivided into subcontinents that are isolated by geological features. The prototype of this is the Indian subcontinent. Islands are usually considered to belong geographically to the continent they are closest to. The Coral Sea and South Pacific islands may be associated with Australia/Australasia to form the "continent" of Oceania (though the Pacific islands without Australia are also called Oceania). The British Isles have always been considered part of Europe, and Greenland is considered part of North America. When the Continent is referred to without clarification by a speaker of British English, it is usually presumed to mean Continental Europe, that is Europe, explicitly excluding Great Britain and Ireland. The Continental United States excludes Hawaii. Contiguous or Co(n)terminous United States means the United States without Alaska or Hawaii (the "Lower 48"), but it is very common for people to say continental for contiguous. See also List of countries by continent, Satellite Images of Continents.

Geologic continents

Geologically, the surface of Earth consists of many tectonic plates, consisting of rigid lithospheric mantle and crust moving together over the much less viscous asthenosphere. Continental crust is primarily granitic in composition, overlain by sedimentary and metamorphic rocks. Much of the continental crust extends above sea level as dry land. Oceanic crust is basaltic in composition, and much thinner than continental crust, thus generally lying below sea level. Although from a human perspective shallow inland seas such as the Bering Sea appear to divide up land masses into continents, such ephemeral features do not define continents geologically. For instance, many times over the past few million years, the continents of Eurasia and America were connected by dry land. A geologic continent, therefore, is a continuous piece of continental crust, whether wet or dry at a particular time. As such, Laurasia and Africa-Arabia are one continent, which for the past three million years has also been linked to South America. This world-spanning land mass has no name except for the Classical meaning of "The Continent". The other large geologic continents are Sahul and Antarctica, but there are many so-called microcontinents as well: Madagascar, the Seychelles (the northern Mascarene Plateau), New Zealand, New Caledonia, etc., which are splinters of the ancient supercontinent of Gondwana. Note that volcanic Iceland is an exposed bit of oceanic crust at the mid-ocean ridge, and therefore not a microcontinent. Likewise, the British Isles, Sri Lanka, Borneo, and Newfoundland are integral parts of the Laurasian continent which happen to be separated by shallow (and temporary) inland seas flooding its margins.

Tectonic plates

During the 20th century, it became accepted by geologists that continents move location on the face of the planet over the geologic timescale, a process known as continental drift, explained by the theory of plate tectonics. It is the tectonic plates that have drifted, broken apart and joined together over time to give rise to the continents we now recognize. Consequently, in the geological past and prior to the present continents, other continents existed - see :Category:Historical continents. Occasionally there are calls for the continents to be defined by the tectonic plates that carry them. However, not only would this make Arabia on the Arabian plate and India on the Indian plate continents, but also Central America on the Caribbean plate and California on the Pacific plate, and this definition has never been widely accepted.

Southern Ocean

The Southern Ocean is the body of water encircling the continent of Antarctica. It is the world's fourth largest ocean and the latest defined, having been accepted by a decision of the International Hydrographic Organization in 2000, though the term has long been traditional among mariners. This change reflects the recent findings in oceanography of the importance of ocean currents. Before that, the Atlantic, Pacific and Indian Oceans were considered to extend to Antarctica, which definition is still used by some geographic authorities including the National Geographic Society. National Geographic Society

Geography

It is oceanographically defined as an ocean connected with the Antarctic Circumpolar Current, which circulates around Antarctica. It includes Amundsen Sea, Bellingshausen Sea, part of the Drake Passage, Ross Sea, a small part of the Scotia Sea, and Weddell Sea. The total area is 20,327,000 km², and the coastline length is 17,968 km. The geographic coordinates is nominally, but the Southern Ocean has the unique distinction of being a large circumpolar body of water totally encircling the continent of Antarctica; this ring of water lies between 60 degrees south latitude and the coast of Antarctica, and encompasses 360 degrees of longitude. This definition is, however, not universal. In Australia the Southern Ocean is defined in the same manner as the IHO but also includes the entire body of water between Antarctica and the south coasts of Australia and New Zealand, and is marked as such on maps. In particular, coastal maps of Tasmania and South Australia always label the sea areas as Southern Ocean and never Indian Ocean. [http://aadc-maps.aad.gov.au/database/mapcat/antarctica/aust_to_ant_jan04.pdf Map showing Australian definition of the Southern Ocean] (PDF) The Southern Ocean was formed oceanographically when Antarctica and South America moved apart opening the Drake Passage and the Antarctic Circumpolar Current was formed roughly 30 million years ago, which makes the ocean much younger than other oceans. The major chokepoint is the Drake Passage. The Polar Front (Antarctic Convergence) is the best natural definition of the northern extent of the Southern Ocean; it is a distinct region at the middle of the Antarctic Circumpolar Current that separates the very cold polar surface waters to the south from the warmer waters to the north; the Front and the Current extend entirely around Antarctica, reaching south of 60 degrees south near New Zealand and near 48 degrees south in the far South Atlantic coinciding with the path of the maximum westerly winds. Image:Iceedgekils.gif The packice zone pulsates over the year.

Climate

Sea temperatures vary from about 28 to 50 °F (-2 to 10 °C). Cyclonic storms travel eastward around the continent and frequently are intense because of the temperature contrast between ice and open ocean. The ocean area from about latitude 40 south to the Antarctic Circle has the strongest average winds found anywhere on Earth. In winter the ocean freezes outward to 65 degrees south latitude in the Pacific sector and 55 degrees south latitude in the Atlantic sector, lowering surface temperatures well below 0 degrees Celsius; at some coastal points intense persistent drainage winds from the interior keep the shoreline ice-free throughout the winter.

Terrain

The Southern Ocean is deep, 4,000 to 5,000 meters over most of its extent with only limited areas of shallow water. The antarctic continental shelf is generally narrow and unusually deep, its edge lying at depths of 400 to 800 meters (the global mean is 133 meters). The Antarctic ice pack grows from an average minimum of 2.6 million square kilometers in March to about 18.8 million square kilometers in September, more than a sevenfold increase in area. The Antarctic Circumpolar Current (21,000 km in length) moves perpetually eastward; it is the world's largest ocean current, transporting 130 million cubic meters of water per second - 100 times the flow of all the world's rivers.

Elevation extremes


- lowest point: -7,235 m at the southern end of the South Sandwich Trench, at 60°00'S, 024°W
- highest point: sea level 0 m.

Natural resources


- Probable large and possible giant oil and gas fields on the continental margin
- Manganese nodules
- Possible placer deposits
- Sand and gravel
- Fresh water as icebergs
- Squid, whales, seals, krill and various fishes

Natural hazards

Huge icebergs with drafts up to several hundred meters; smaller bergs and iceberg fragments; sea ice (generally 0.5 to 1 meter thick) with sometimes dynamic short-term variations and with large annual and interannual variations; deep continental shelf floored by glacial deposits varying widely over short distances; high winds and large waves much of the year; ship icing, especially May-October; most of the region is remote from sources of search and rescue.

Environment

Current issues


- Increased solar ultraviolet radiation resulting from the Antarctic ozone hole, reducing marine primary productivity (phytoplankton) by as much as 15% and damaging the DNA of some fish
- illegal, unreported, and unregulated fishing, especially the landing of an estimated five to six times more Patagonian toothfish than the regulated fishery, which is likely to affect the sustainability of the stock
- high incidental mortality of seabirds resulting from long-line fishing for toothfish
- the now-protected fur seal population is making a strong comeback after severe overexploitation in the 18th and 19th centuries

International agreements

The Southern Ocean is subject to all international agreements regarding the world's oceans. In addition, it is subject to these agreements specific to the region: International Whaling Commission (prohibits commercial whaling south of 40 degrees south [south of 60 degrees south between 50 degrees and 130 degrees west]); Convention for the Conservation of Antarctic Seals (limits sealing); Convention on the Conservation of Antarctic Marine Living Resources (regulates fishing)
- note: many nations prohibit mineral resource exploration and exploitation south of the fluctuating Polar Front (Antarctic Convergence) which is in the middle of the Antarctic Circumpolar Current and serves as the dividing line between the very cold polar surface waters to the south and the warmer waters to the north.

Economy overview

Fisheries in 1998-1999 (1 July to 30 June) landed 119,898 metric tons, of which 85% was krill and 14% Patagonian toothfish. International agreements were adopted in late 1999 to reduce illegal, unreported, and unregulated fishing, which in the 1998-1999 season landed five to six times more Patagonian toothfish than the regulated fishery. In the 1998-1999 Antarctic summer 10,013 tourists, most of them seaborne, visited the Southern Ocean and Antarctica, compared to 9,604 the previous year. Nearly 16,000 tourists are expected during the 1999-2000 season.

Ports and harbors

Esperanza Base, Mawson Station, McMurdo Station, Palmer Station, Scott Base, and offshore anchorages in Antarctica
- note: few ports or harbors exist on the southern side of the Southern Ocean; ice conditions limit use of most of them to short periods in midsummer; even then some cannot be entered without icebreaker escort; most antarctic ports are operated by government research stations and, except in an emergency, are not open to commercial or private vessels; vessels in any port south of 60 degrees south are subject to inspection by Antarctic Treaty observers.

Transportation note

The Drake Passage offers an alternative to transit through the Panama Canal.

Pacific Ocean

:For other meanings of Pacific, see Pacific (disambiguation). The Pacific Ocean (from the Latin name Mare Pacificum, "peaceful sea", bestowed upon it by the Portuguese explorer Ferdinand Magellan) is the world's largest body of water. It encompasses a third of the Earth's surface, having an area of 179.7 million km² (69.4 million sq miles). Extending approximately 15,500 km (9,600 miles) from the Bering Sea in the Arctic to the icy margins of Antarctica's Ross Sea in the south (although the Antarctic regions of the Pacific are sometimes described as part of the circumpolar Southern Ocean)the Pacific reaches its greatest east-west width at about 5°N latitude, where it stretches approximately 19,800 km (12,300 miles) from Indonesia to the coast of Colombia. The western limit of the ocean is often placed at the Strait of Malacca. The lowest point on earth—the Mariana Trench—lies some 10,911 m (35,797 ft) below sea level. The Pacific contains about 25,000 islands (more than the total number in the rest of the world's oceans combined), the majority of which are found south of the equator. (See: Pacific Islands.) Along the Pacific Ocean's irregular western margins lie many seas, the largest of which are the Celebes Sea, Coral Sea, East China Sea, Sea of Japan, South China Sea, Sulu Sea, Tasman Sea, and Yellow Sea. The Straits of Malacca joins the Pacific and the Indian Oceans on the west, and the Straits of Magellan links the Pacific with the Atlantic Ocean on the east. As the Pacific straddles the ±180° longitude where East becomes West, the Asian side of the ocean (where latitudes are E) is correctly referred to as East Pacific and the opposite side (eastwards) where latitudes are W is the West Pacific. To retain the popular "left is western" and "right is eastern" means of reference, the Western Pacific is thus the East Pacific and the Eastern Pacific the West Pacific. The International Date Line follows the ±180° longitude to the greater part of its North-South demarcation but veers far eastwards around Kiribati (Caroline Island, which, not coincidentally, was renamed Millennium Island) and westwards round the Aleutian Islands as can be seen on the map at International Date Line. For most of Ferdinand Magellan's voyage from the Straits of Magellan to the Philippines, the Portuguese explorer indeed found the ocean peaceful. However, the Pacific is not always peaceful. Many typhoons and hurricanes batter the islands of the Pacific and the lands around the Pacific rim are full of volcanoes and often rocked by earthquakes. Tsunamis, caused by underwater earthquakes, have devastated many islands and wiped out whole towns. Tsunami

Ocean bottom

The ocean floor of the central Pacific basin is relatively uniform, an abyssal plain with a mean depth of about 4270 m (14,000 ft). The major irregularities in the basin are the extremely steep-sided, flat-topped submarine peaks known as seamounts. The western part of the floor consists of mountain arcs that rise above the sea as island groups, such as the Solomon Islands and New Zealand, and deep oceanic trenches, such as the Mariana Trench, the Philippine Trench, and the Tonga Trench. Most of the trenches lie adjacent to the outer margins of the wide western Pacific continental shelf. Along the eastern margin of the Pacific Basin is the East Pacific Rise, which is a part of the worldwide mid-oceanic ridge. About 3000 km (1800 miles) across, the rise stands about 3 km (2 miles) above the adjacent ocean floor. Because a relatively small land area drains into the Pacific, and because of the ocean's immense size, most sediments are authigenic or pelagic in origin. Authigenic sediments include montmorillonite and phillipsite. Pelagic sediments derived from seawater include pelagic red clays and the skeletal remains of sea life. Terrigenous sediments eroded from land masses are confined to narrow marginal bands close to land.

Elevation extremes


- lowest point: -10,924 m (-35,840 ft). at the bottom of the Mariana Trench
- highest point: 0 m (0 ft), sea level.

Water characteristics

Water temperatures in the Pacific vary from freezing in the poleward areas to about 29°C (84°F) near the equator. Salinity also varies latitudinally. Water near the equator is less salty than that found in the mid-latitudes because of abundant equatorial precipitation throughout the year. Poleward of the temperate latitudes salinity is also low, because little evaporation of seawater takes place in these frigid areas. The surface circulation of Pacific waters is generally clockwise in the Northern Hemisphere (the North Pacific Gyre) and anti-clockwise in the Southern Hemisphere. The North Equatorial Current, driven westward along latitude 15°N by the trade winds, turns north near the Philippines to become the warm Japan or Kuroshio Current. Turning eastward at about 45°N, the Kuroshio forks and some waters move northward as the Aleutian Current, while the rest turn southward to rejoin the North Equatorial Current. The Aleutian Current branches as it approaches North America and forms the base of an anti-clockwise circulation in the Bering Sea. Its southern arm becomes the chilled slow, south-flowing California Current. The South Equatorial Current, flowing west along the equator, swings southward east of New Guinea, turns east at about 50°S, and joins the main westerly circulation of the Southern Pacific, which includes the Earth-circling Antarctic Circumpolar Current. As it approaches the Chilean coast, the South Equatorial Current divides; one branch flows around Cape Horn and the other turns north to form the Peru or Humboldt Current.

Climate

Only the interiors of the large land masses of Australia, New Guinea, and New Zealand escape the pervasive climatic influence of the Pacific. Within the area of the Pacific, five distinctively different climatic regions exist: the mid-latitude westerlies, the trades, the monsoon region, the typhoon region, and the doldrums. Mid-latitude westerly air streams occur in both northerly and southerly latitudes, bringing marked seasonal differences in temperature. Closer to the equator, where most of the islands lie, steadily blowing trade winds allow for relatively constant temperatures throughout the year of 21-27°C (70-81°F). The monsoon region lies in the far western Pacific between Japan and Australia. Characteristic of this climatic region are winds that blow from the continental interior to the ocean in winter and in the opposite direction in summer. Consequently, a marked seasonality of cloudiness and rainfall occurs. Typhoons often cause extensive damage in the west and southwest Pacific. The greatest typhoon frequency exists within the triangle from southern Japan to the central Philippines to eastern Micronesia. Although more poorly defined than the other climatic regions, two major doldrum areas lie within the ocean, one located off the western shores of Central America and the other within the equatorial waters of the western Pacific. Both areas are noted for their high humidity, considerable cloudiness, light fluctuating winds, and frequent calms.

Geology

The Andesite Line is the most significant regional distinction in the Pacific. It separates the deeper, basic igneous rock of the Central Pacific Basin from the partially submerged continental areas of acidic igneous rock on its margins. The Andesite Line follows the western edge of the islands off California and passes south of the Aleutian arc, along the eastern edge of the Kamchatka Peninsula, the Kuril Islands, Japan, the Mariana Islands, the Solomon Islands, and New Zealand. The dissimilarity continues northeastward along the western edge of the Albatross Cordillera along South America to Mexico, returning then to the islands off California. Indonesia, the Philippines, Japan, New Guinea, and New Zealand—all eastward extensions of the continental blocks of Australia and Asia—lie outside the Andesite Line. Within the closed loop of the Andesite Line are most of the deep troughs, submerged volcanic mountains, and oceanic volcanic islands that characterize the Central Pacific Basin. It is here that basaltic lavas gently flow out of rifts to build huge dome-shaped volcanic mountains whose eroded summits form island arcs, chains, and clusters. Outside the Andesite Line, volcanism is of the explosive type, and the Pacific Ring of Fire is the world's foremost belt of explosive volcanism.

Landmasses

The largest landmass entirely within the Pacific Ocean is the island of New Guinea— the second largest in the world. Almost all of the smaller islands of the Pacific lie between 30°N and 30°S, extending from South-east Asia to Easter Island; the rest of the Pacific Basin is almost entirely submerged. The great triangle of Polynesia, connecting Hawaii, Easter Island, and New Zealand, encompasses the island arcs and clusters of the Cook, Marquesas, Samoa, Society, Tokelau, Tonga, and Tuamotu islands. North of the equator and west of the international date line are the numerous small islands of Micronesia, including the Caroline Islands, the Marshall Islands, and the Mariana Islands. In the southwestern corner of the Pacific lie the islands of Melanesia, dominated by New Guinea. Other important island groups of Melanesia include the Bismarck Archipelago, Fiji, New Caledonia, the Solomon Islands, and Vanuatu. Islands in the Pacific Ocean are of four basic types: continental islands, high islands, coral reefs, and uplifted coral platforms. Continental islands lie outside the Andesite Line and include New Guinea, the islands of New Zealand, and the Philippines. These islands are structurally associated with the nearby continents. High islands are of volcanic origin, and many contain active volcanoes. Among these are Bougainville, Hawaii, and the Solomon Islands. The third and fourth types of islands are both the result of coralline island building. Coral reefs are low-lying structures that have built up on basaltic lava flows under the ocean's surface. One of the most dramatic is the Great Barrier Reef off northeastern Australia. A second island type formed of coral is the uplifted coral platform, which is usually slightly larger than the low coral islands. Examples include Banaba (formerly Ocean Island) and Makatea in the Tuamotu group of French Polynesia.

History and economy

See the Oceania article for information on one set of the Pacific Island states listed below here. Important human migrations occurred in the Pacific in prehistoric times, most notably those of Polynesians from Tahiti to Hawaii and New Zealand. The ocean was sighted by Europeans early in the 16th century, first by Vasco Núñez de Balboa (1513) and then by Ferdinand Magellan, who crossed the Pacific during his circumnavigation (1519-1522). In 1564 conquistadors crossed the ocean from Mexico led by Miguel López de Legazpi who sailed to the Philippines and Mariana Islands. For the remainder of the 16th century Spanish influence was paramount, with ships sailing from Spain to the Philippines, New Guinea, and the Solomons. The Manila Galleons linked Manila and Acapulco. During the 17th century the Dutch, sailing around southern Africa, dominated discovery and trade; Abel Janszoon Tasman discovered (1642) Tasmania and New Zealand. The 18th century marked a burst of exploration by the Russians in Alaska and the Aleutian Islands, the French in Polynesia, and the British in the three voyages of James Cook (to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest). Growing imperialism during the 19th century resulted in the occupation of much of Oceania by Great Britain and France, followed by the United States. Significant contributions to oceanographic knowledge were made by the voyages of the HMS Beagle in the 1830s, with Charles Darwin aboard; the HMS Challenger during the 1870s; the U.S.S. Tuscarora (1873-76); and the German Gazelle (1874-1876). Although the United States took the Philippines in 1898, Japan controlled the western Pacific by 1914, and occupied many other islands during World War II. By the end of that war the U.S. Pacific Fleet was the virtual master of the ocean. Seventeen independent states are located in the Pacific: Australia, Fiji, Japan, Kiribati, Marshall Islands, Micronesia, Nauru, New Zealand, Palau, Papua New Guinea, the Philippines, Samoa, Solomon Islands, Republic of China (Taiwan), Tonga, Tuvalu, and Vanuatu. Eleven of these nations have achieved full independence since 1960. The Northern Mariana Islands are self-governing with external affairs handled by the United States, and Cook Islands and Niue are in similar relationships with New Zealand. Also within the Pacific are the U.S. state of Hawaii and several island territories and possessions of Australia, Chile, Ecuador, France, Japan, New Zealand, the United Kingdom, and the United States. The exploitation of the Pacific's mineral wealth is hampered by the ocean's great depths. In shallow waters of the continental shelves off the coasts of Australia and New Zealand, petroleum and natural gas are extracted, and pearls are harvested along the coasts of Australia, Japan, Papua New Guinea, Nicaragua, Panama, and the Philippines, although in sharply declining volume. The Pacific's greatest asset is its fish. The shoreline waters of the continents and the more temperate islands yield herring, salmon, sardines, snapper, swordfish, and tuna, as well as shellfish. In 1986, the member nations of the South Pacific Forum declared the area a nuclear-free zone in an effort to halt nuclear testing and prevent the dumping of nuclear waste there.

East Timor

The Democratic Republic of Timor-Leste (pron. IPA //; also known as East Timor or Timor Lorosae) is an Australasian country which recently acquired statehood, located geographically in Oceania, although it is sometimes assigned to Asia instead (see Line dividing Asia and Oceania). It consists of the eastern half of the island of Timor, the nearby islands of Atauro and Jaco, and Oecussi-Ambeno, an exclave of East Timor situated on the northwestern side of the island, surrounded by West Timor. Formerly Portuguese Timor, East Timor was invaded by Indonesia in 1975, which occupied it until 1999. Following the UN-sponsored act of self-determination that year, Indonesia relinquished control of the territory, which achieved full independence on May 20, 2002. With the Philippines, East Timor is one of only two majority Roman Catholic countries in Asia.

History

Main article: History of East Timor The Portuguese were the first Europeans to arrive in the area, in the 16th century, and they established an isolated presence on the island of Timor, while the surrounding islands came under Dutch control. In late 1941 Portuguese Timor was briefly occupied by Dutch and Australian troops, who aimed to thwart a Japanese invasion of the island. The Portuguese Governor protested the invasion, and the Dutch forces returned to the Dutch side of the island. When the Japanese landed and drove the small Australian force out of Dili, the mountainous interior became the scene of a guerilla campaign, known as Battle of Timor, waged by Allied forces and Timorese volunteers against the Japanese. The struggle resulted in the deaths of between 40,000 and 70,000 Timorese. Following the end of the War, Portuguese control was reinstated. The process of decolonisation in Portuguese Timor began in 1974, following the change of government in Portugal in the wake of the Carnation Revolution. Owing to political instability and more pressing concerns with decolonisation in Angola and Mozambique, Lisbon effectively abandoned East Timor, which unilaterally declared itself independent on November 28, 1975. Nine days later, it was invaded and occupied by Indonesian forces before this could be internationally recognised. Indonesia alleged that the popular East Timorese FRETILIN party, which received some vocal support from the People's Republic of China, was communist. With the American cause in South Vietnam lost and fearing a Communist domino effect in Southeast Asia, the U.S., along with ally Australia, did not object to the pro-Western Indonesian government's actions, despite Portugal being a NATO founding member. The Indonesian invasion was launched over the western border on 16 October 1975. The day before the invasion of Dili and subsequent annexation, U.S. President Gerald Ford and Secretary of State Henry Kissinger had met President Suharto in Jakarta where Ford made clear that "we will not press you on the issue." Several U.S. administrations up to and including that of Bill Clinton did not ban arms sales to the Indonesian government, though the latter did eventually end U.S. support of Suharto's regime. The territory was declared the 27th province of Indonesia in July 1976 as Timor Timur. However, internationally its legal status was that of a "non-self governing territory under Portuguese administration." Indonesian rule in East Timor was marked by extreme violence and brutality. It has been claimed that during the invasion and 27-year occupation, 100,000 to 250,000 people were killed in an initial population of about 600,000 at the time of the invasion. Following a UN-sponsored agreement between Indonesia, Portugal and the US, on August 30, 1999, a United Nations-supervised popular referendum was held, the East Timorese voted for full independence from Indonesia, but violent clashes, instigated primarily by anti-independence militias (aided by elements of the Indonesian military, see Scorched Earth Operation), broke out soon afterwards. A peacekeepeing force (INTERFET, led by Australia) intervened to restore order. Militia fled across the border into Indonesia, from which they attempted sporadic raids, particularly along the New Zealand Army-held southern half of the main border. As these raids were repelled and international moral opinion forced Indonesia to withdraw tacit support, the militia dispersed. INTERFET was replaced by a UN force. Independence was recognised by Portugal after a visit of Xanana Gusmão to Lisbon to choose the date. They decided May 20, 2002 and East Timor joined the UN on September 27 of that year.

Politics

Main article: Politics of East Timor The Head of state of the East Timorese republic is the president, who is elected by popular vote for a five-year term and whose role is largely symbolic, though he is able to veto some legislation. Following elections, the president appoints as prime minister the leader of the majority party or majority coalition. As head of government the prime minister presides over the Council of State or cabinet. The unicameral Timorese parliament is the National Parliament or Parlamento Nacional, whose members are elected by popular vote to a five-year term. The number of seats can vary from a minimum of 52 to a maximum of 65, though it exceptionally has 88 members at present, due to this being its first term of office. The Timorese constitution was modelled on that of Portugal. The country is still in the process of building its administration and governmental institutions.
