Leap year

A leap year (or intercalary year) is a year containing an extra day or month in order to keep the calendar year in sync with an astronomical or seasonal year. Seasons and astronomical events do not repeat at an exact number of days, so a calendar which had the same number of days in each year would over time drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected. Leap years (which keep the calendar in sync with the year) should not be confused with leap seconds (which keep clock time in sync with the day).

Gregorian calendar

The Gregorian calendar, the current standard calendar in most of the world, adds a 29th day to February in all years evenly divisible by 4, except for century years (those ending in -00), which receive the extra day only if they are evenly divisible by 400. Thus 1996 was a leap year whereas 1999 was not, and 1600, 2000 and 2400 are leap years but 1700, 1800, 1900 and 2100 are not. The reasoning behind this rule is as follows:
- The Gregorian calendar is designed to keep the vernal equinox on or close to March 21, so that the date of Easter (celebrated on the Sunday after the 14th day of the Moon that falls on or after 21 March) remains correct with respect to the vernal equinox.
- The vernal equinox year is currently about 365.242375 days long.
- The Gregorian leap year rule gives an average year length of 365.2425 days. This difference of a little over 0.0001 days means that in around 8,000 years, the calendar will be about one day behind where it should be. But in 8,000 years' time the length of the vernal equinox year will have changed by an amount we can't accurately predict (see below). So the Gregorian leap year rule does a good enough job.

Which day is the leap day?

The Gregorian calendar is a modification of the Julian calendar first used by the Romans. The Roman calendar originated as a lunar calendar (though from the 5th century BC it no longer followed the real moon) and named its days after three of the phases of the moon: the new moon (calends, hence "calendar"), the first quarter (nones) and the full moon (ides). Days were counted down (inclusively) to the next named day, so 24 February was ante diem sextum calendas martii ("the sixth day before the calends of March"). Since 45 BC, February in a leap year had two days called "the sixth day before the calends of March". The extra day was originally the second of these, but since the third century it was the first. Hence the term bissextile day for 24 February in a bissextile year. Where this custom is followed, anniversaries after the inserted day are moved in leap years. For example, the former feast day of Saint Matthias, 24 February in ordinary years, would be 25 February in leap years. This historical nicety is, however, in the process of being discarded: The European Union declared that, starting in 2000, 29 February rather than 24 February would be leap day, and the Roman Catholic Church also now uses 29 February as leap day. The only tangible difference is felt in countries that celebrate feast days.

Julian calendar

The Julian calendar adds an extra day to February in years divisible by 4. This rule gives an average year length of 365.25 days. The excess of about 0.0076 days with respect to the vernal equinox year means that the vernal equinox moves a day earlier in the calendar every 130 years or so.

Revised Julian Calendar

The Revised Julian calendar adds an extra day to February in years divisible by 4, except for years divisible by 100 that do not leave a remainder of 200 or 600 when divided by 900. This rule agrees with the rule for the Gregorian calendar until 2799. The first year that dates in the Revised Julian calendar will not agree with the those in the Gregorian calendar will be 2800, because it will be a leap year in the Gregorian calendar but not in the Revised Julian calendar. This rule gives an average year length of 365.242222… days. This is a very good approximation to the mean tropical year, but because the vernal equinox tropical year is slightly longer, the Revised Julian calendar does not do as good a job as the Gregorian calendar of keeping the vernal equinox on or close to 21 March.

Chinese calendar

The Chinese calendar is lunisolar, so a leap year has an extra month, often called an embolismic month after the Greek word for it. In the Chinese calendar the leap month is added according to a complicated rule, which ensures that month 11 is always the month that contains the northern winter solstice. The intercalary month takes the same number as the preceding month; for example, if it follows the second month then it is simply called "leap second month".

Hebrew calendar

The Hebrew calendar is also lunisolar with an embolistic month. In the Hebrew calendar the extra month is called Adar Alef (first Adar) and is added before Adar, which then becomes Adar Sheni (second Adar). According to the Metonic cycle, this is done seven times every nineteen years, specifically, in years, 3, 6, 8, 11, 14, 17, and 19. In addition, the Hebrew calendar has postponement rules that postpone the start of the year by one or two days. The year before the postponement gets one or two extra days, and the year whose start is postponed loses one or two days. These postponement rules reduce the number of different combinations of year length and starting day of the week from 28 to 14, and regulate the location of certain religious holidays in relation to the Sabbath.

Hindu Calendar

In the Hindu calendar, which is a lunisolar calendar, the embolismic month is called adhika maas (extra month). It is the month in which the sun is in the same sign of the stellar zodiac on two consecutive dark moons.

Iranian calendar

The Iranian calendar also has a single intercalated day once in every four years, but every 33 years or so the leap years will be five years apart instead of four years apart. The system used is more accurate and more complicated, and is based on the time of the March equinox as observed from Teheran. The 33-year period is not completely regular; every so often the 33-year cycle will be broken by a cycle of 29 or 37 years.

Long term leap year rules

The accumulated difference between the Gregorian calendar and the vernal equinoctial year amounts to 1 day in about 8,000 years. This suggests that the calendar needs to be improved by another refinement to the leap year rule: perhaps by avoiding leap years in years divisible by 8,000. (The most common such proposal is to avoid leap years in years divisible by 4,000 [http://www.google.com/search?q=%22gregorian+calendar%22+error+%22leap+year%22+4000]. This is based on the difference between the Gregorian calendar and the mean tropical year. Others claim, erroneously, that the Gregorian calendar itself already contains a refinement of this kind [http://www.straightdope.com/mailbag/mleapyr.html].) However, there is little point in planning a calendar so far ahead because over a timescale of tens of thousands of years the number of days in a year will change for a number of reasons, most notably: #Precession of the equinoxes moves the position of the vernal equinox with respect to perihelion and so changes the length of the vernal equinoctial year. #Tidal acceleration from the sun and moon slows the rotation of the earth, making the day longer. In particular, the second component of change depends on such things as post-glacial rebound and sea level rise due to climate change. We can't predict these changes accurately enough to be able to make a calendar that will be accurate to a day in tens of thousands of years.

Marriage proposal

There is a tradition, said to go back to Saint Patrick and Saint Bridget in 5th century Ireland, whereby women may only make marriage proposals in leap years.

Saint Patrick and the leap year

:Saint Patrick, having driven the frogs out of the bogs was walking along the shores of Lough Neagh, when he was accosted by Saint Bridget in tears, and was told that a mutiny had broken out in the nunnery over which she presided, the ladies claiming the right of popping the question. :Saint Patrick said he would concede them the right every seventh year, when Saint Bridget threw her arms round his neck, and exclaimed, "Arrah, Pathrick, jewel, I daurn't go back to the girls wid such a proposal. Make it one year in four." Saint Patrick replied, "Bridget, acushla, squeeze me that way again, an' I'll give ye leap-year, the longest of the lot." Saint Bridget, upon this, popped the question to St Patrick himself, who, of course, could not marry: so he patched up the difficulty as best he could with a kiss and a silk gown. (Source: Evans, Ivor H, Brewer's Dictionary of Phrase and Fable, Cassell, London, 1988) According to a 1288 law in Scotland, fines were levied if the proposal was refused by the man; compensation ranged from a kiss to a silk gown to soften the blow. Because men felt that put them at too great a risk, the tradition was in some places tightened to restricting female proposals to 29 February.

Birthdays

A person who was born on 29 February may be called a "leapling". In non-leap years they usually celebrate their birthday on 28 February or 1 March. There are many instances in children's literature where a person's claim to be only a quarter of their actual age turns out be based on counting their leap-year birthdays. A similar device is used in the plot of the Gilbert and Sullivan operetta The Pirates of Penzance.

Roman Empire

:For other uses, see Roman Empire (disambiguation) The Roman Empire is the term conventionally used to describe the Ancient Roman polity in the centuries following its reorganization under the leadership of Octavian (better known as Caesar Augustus), until its radical reformation in what was later to be known as the Byzantine Empire. Roman Empire is also used as translation of the expression Imperium Romanum, probably the best known Latin expression where the word "imperium" is used in the meaning of a territory, the "Roman Empire", as that part of the world where Rome ruled. The expansion of this Roman territory beyond the borders of the initial city-state of Rome had started long before the state organisation turned into an Empire. One of the first historians to describe this expansion of the Roman territory was the Greek Polybius, writing in the Epoch of the Roman Republic. In the centuries before the autocracy of Augustus, Rome had already accumulated a collection of tribute-states beyond the Italian Peninsula, including former Mediterranean competitors Syracuse and Carthage. In the late Republic Augustus (then still "Octavian") added Egypt definitively to the Imperium Romanum. The remainder of this article treats the Roman Empire as Imperial state (see Roman Kingdom and Roman Republic for development of the territory in earlier times). Augustus' reforms turning the Roman state into an Empire survived mostly unchanged until the Diocletian reform at end of the 3rd century, which turned the empire into a tetrarchy. While the political form given by Diocletian was short-lived, it led to the division of the Empire into two halves. This allowed Roman rule to continue for two more centuries over the whole empire, although divided into the Eastern and the Western Roman Empire. The end of the Western Empire is traditionally set in 476, when Odovacar deposed the last Emperor and sent the Imperial insignia to Constantinople; henceforth he nominally ruled as dux on behalf of Constantinople. After another millennium, in 1453, the Eastern Empire, better known as the Byzantine Empire, fell to the Ottoman Turks. From Augustus to the Fall of the Western Empire Rome dominated the region of Western Eurasia, comprising over half its population. The Roman Empire's influence on government, law, military, and monumental architecture, as well as many other aspects of Western life remains inescapable. The Greeks adopted the Roman name in the Middle Ages and were known as Romans, a trend that survives until today in Greece, a result of their cultural position (see Names of the Greeks). Roman titles of power were adopted by successor states and other entities with imperial pretensions, including the Frankish kingdom, the Holy Roman Empire, the first and second Bulgarian empires, the Russian/Kiev dynasties, and the German Empire. See also Roman culture.
Historians' viewpoints on the evolution of Imperial Rome
Because the empire of Rome lasted for such a long period of time (31 BC–1453), there are certain alternative names used by historians to distinguish various semantic periods or eras. Such names include Byzantine Empire, Eastern Roman Empire and Western Roman Empire, which are used interchangeably throughout this article to mean the same as Roman Empire (or the Western or Eastern part thereof). For many years historians made a distinction between the Principate, the period from Augustus until the Crisis of the Third Century, and the Dominate, the period from Diocletian until the end of the Empire in the West. According to this theory, during the Principate (from the Latin word princeps, meaning "first citizen", the only title Augustus would permit himself) the realities of dictatorship were concealed behind Republican forms; while during the Dominate (from the word dominus, meaning "Master") imperial power showed its naked face, with golden crowns and ornate imperial ritual. More recently historians established that the situation was far more nuanced: certain historical forms continued until the Byzantine period, more than one thousand years after they were created, and displays of imperial majesty were common from the earliest days of the Empire.
Age of Augustus (31 BC–AD 14)

Political developments
Latin As a matter of convenience, the Roman Empire is held to have begun with the constitutional settlement following the Battle of Actium in 31 BC. In fact the Republican institutions at Rome had been destroyed over the preceding century and Rome had been in continuous crisis with periods of dictatorial rule since Sulla. The long, peaceful and consensual reign of Augustus greatly changed the view toward hereditary monarchy. Rome–the city that had not too long before assassinated its leader, Julius Caesar, when his ambitions seemed to threaten the republic–now placidly accepted one man rule. Augustus' reign was notable for several long-lasting achievements that would define the Empire:
- Creation of an hereditary office, which we refer to as Emperor of Rome.
- Fixation of the payscale. Duration of Roman military service marked the final step in the evolution of the Roman Army from a citizen army to a professional one.
- Creation of the Praetorian Guard, which would make and unmake emperors for centuries.
- Expansion to the natural borders of the Empire. The borders reached upon Augustus' death remained the limits of Empire, with minimal exceptions, for the next four hundred years.
- Development of trade links with regions as far as India and China.
- Creation of a civil service outside of the Senatorial structure, leading to a continuous weakening of Senatorial authority.
- Enactment of the lex Julia of 18 BC and the lex Papia Poppaea of AD 9, which rewarded childbearing and penalized celibacy.
- Promulgation of the cult of the Deified Julius Caesar throughout the Empire. This tradition of deifying the Emperor upon his death lasted until the time of Constantine, who was made both a Roman god and "the Thirteenth Apostle" upon his death.
Cultural developments
:Main article: Roman culture The Augustan period saw a tremendous outpouring of cultural achievement in the areas of poetry, history, sculpture and architecture. At the same time, a tremendous outpouring of energy in founding colonies and municipia, unrivalled in Rome before or after, succeeded in Romanizing extensive territories in the East, in Africa, in Hispania and Gaul, beyond those areas that were traditionally within the Roman sphere of influence.
Sources
The Age of Augustus is paradoxically far more poorly documented than the Late Republican period that preceded it. While Livy wrote his magisterial history during Augustus' reign and his work covered all of Roman history through 9 BC, only epitomes survive of his coverage of the Late Republican and Augustan periods. Our important primary sources for this period include the:
- Res Gestae Divi Augusti, Augustus' highly partisan autobiography,
- Historiae Romanae by Velleius Paterculus, a disorganized work which remains the best annals of the Augustan period, and
- Controversiae and Suasoriae of Seneca the Elder. Though primary accounts of this period are few, works of poetry, legislation and engineering from this period provide important insights into Roman life. Archeology, including maritime archeology, aerial surveys, epigraphic inscriptions on buildings, and Augustan coinage, has also provided valuable evidence about economic, social and military conditions. Secondary sources on the Augustan Age include Tacitus, Dio Cassius, Plutarch and Suetonius. Josephus' Jewish Antiquities is the important source for Judea in this period, which became a province during Augustus' reign.
Julio-Claudian dynasty: Augustus' heirs
Augustus, leaving no sons, was succeeded by his stepson Tiberius, the son of his wife Livia from her first marriage. Augustus was a scion of the gens Julia (the Julian family), one of the most ancient patrician clans of Rome, while Tiberius was a scion of the gens Claudia, only slightly less ancient than the Julians. Their three immediate successors were all descended both from the gens Claudia, through Tiberius' brother Nero Claudius Drusus, and from gens Julia, either through Julia Caesaris, Augustus' daughter from his first marriage (Caligula and Nero), or through Augustus' sister Octavia (Claudius). Historians thus refer to their dynasty as "Julio-Claudian".
Tiberius (14–37)
The early years of Tiberius' reign were peaceful and relatively benign. Tiberius secured the power of Rome and enriched her treasury. However, Tiberius' reign soon became characterized by paranoia and slander. In 19, he was popularly blamed for the death of his nephew, the popular Germanicus. In 23 his own son Drusus died. More and more, Tiberius retreated into himself. He began a series of treason trials and executions. He left power in the hands of the commander of the guard, Aelius Sejanus. Tiberius himself retired to live at his villa on the island of Capri in 26, leaving administration in the hands of Sejanus, who carried on the persecutions with relish. Sejanus also began to consolidate his own power; in 31 he was named co-consul with Tiberius and married Livilla, the emperor's niece. At this point he was hoist by his own petard: the Emperor's paranoia, which he had so ably exploited for his own gain, was turned against him. Sejanus was put to death, along with many of his cronies, the same year. The persecutions continued until Tiberius' death in 37.
Caligula (37–41)
At the time of Tiberius' death most of the people who might have succeeded him had been brutally murdered. The logical successor (and Tiberius' own choice) was his grandnephew, Germanicus' son Gaius (better known as Caligula). Caligula started out well, by putting an end to the persecutions and burning his uncle's records. Unfortunately, he quickly lapsed into illness. The Caligula that emerged in late 37 may have suffered from epilepsy, and was probably insane. He ordered his soldiers to invade Britain, but changed his mind at the last minute and had them pick sea shells on the northern end of France instead. It is believed he carried on incestuous relations with his sisters. He had ordered a statue of himself to be erected in the Temple at Jerusalem, which would have undoubtedly led to revolt had he not been dissuaded. In 41, Caligula was assassinated by the commander of the guard Cassius Chaerea. The only member left of the imperial family to take charge was another nephew of Tiberius', Tiberius Claudius Drusus Nero Germanicus, better known as the emperor Claudius.
Claudius (41–54)
Claudius had long been considered a weakling and a fool by the rest of his family. He was, however, neither paranoid like his uncle Tiberius, nor insane like his nephew Caligula, and was therefore able to administer the empire with reasonable ability. He improved the bureaucracy and streamlined the citizenship and senatorial rolls. He also proceeded with the conquest and colonization of Britain (in 43), and incorporated more Eastern provinces into the empire. In Italy, he constructed a winter port at Ostia, thereby providing a place for grain from other parts of the Empire to be brought in inclement weather. On the home front, Claudius was less successful. His wife Messalina cuckolded him; when he found out, he had her executed and married his niece, Agrippina the younger. She, along with several of his freedmen, held an inordinate amount of power over him, and very probably killed him in 54. Claudius was deified later that year. The death of Claudius paved the way for Agrippina's own son, the 16-year-old Lucius Domitius, or, as he was known by this time, Nero.
Nero (54–69)
Initially, Nero left the rule of Rome to his mother and his tutors, particularly Lucius Annaeus Seneca. However, as he grew older, his desire for power increased; he had his mother and tutors executed. During Nero's reign, there were a series of riots and rebellions throughout the Empire: in Britain, Armenia, Parthia, and Judaea. Nero's inability to manage the rebellions and his basic incompetence became evident quickly and in 68, even the Imperial guard renounced him. Nero is best remembered by the rumour that he played the lyre and sang during the Great Fire of Rome, and hence "fiddled while Rome burned" (though the fiddle had yet to be invented). Nero is also remembered for his immense rebuilding of Rome following the fires. Nero committed suicide, and the year 69 (known as the Year of the Four Emperors) was a year of civil war, with the emperors Galba, Otho, Vitellius, and Vespasian ruling in quick succession. By the end of the year, Vespasian was able to solidify his power as emperor of Rome.
Flavian Dynasty
The Flavians, although a relatively short lived dynasty, helped restore stability in an empire on its knees. Although there are criticism of all three, especially based on their more centralized style of rule, it was through the reforms and good rule of the three that helped create a stable empire that would last well into the 3rd Century. However, their backgrounds as a military dynasty led to further irrelevancy of the senate, and the move from princeps, or first citizen, to imperator, or emperor, was finalized during their reign.
Vespasian (69–79)
Vespasian was a remarkably successful Roman general who had been given rule over much of the eastern part of the Roman Empire. He had supported the imperial claims of Galba; however, on his death, Vespasian became a major contender for the throne. After the suicide of Otho, Vespasian was able to hijack Rome's winter grain supply in Egypt, placing him in a good position to defeat his remaining rival, Vitellius. On December 20, 69, some of Vespasian's partisans were able to occupy Rome. Vitellius was murdered by his own troops, and the next day, Vespasian was confirmed as Emperor by the Senate. At the age of 60 and battle hardened he was hardly a charismatic emperor, but he turned out to be an excellent ruler none the less. Although Vespasian was considered quite the autocrat by the senate, he mostly continued the weakening of that body that had been going since the reign of Tiberius. This was typified by his dating his accession to power from July 1, when his troops proclaimed him emperor, instead of December 21, when the Senate confirmed his appointment. Another example was his assumption of the censorship in 73, giving him power over who exactly made up the senate. He used that power to expel dissident senators. At the same time, he increased the number of senators from 200, at that low level due to the actions of Nero and the year of crisis that followed, to 1000, most of the new senators coming not from Rome but from Italy and the urban centers within the western provinces. Vespasian was able to liberate Rome from the financial burdens placed upon it by Nero's excesses and the civil wars. To do this, he not only increased taxes, but created new forms of taxation. Also, through his power as censor he was able to carefully examine the fiscal status of every city and province, many paying taxes based upon information and structures more than a century old. Through this sound fiscal policy, he was able to build up a surplus in the treasury and embark on public works projects. It was he who first commissioned the Roman Colosseum; he also built a forum whose centerpiece was a temple to Peace. In addition, he alloted sizable subsidies to the arts, creating a chair of rhetoric at Rome. Vespasian was also an effective emperor for the provinces in his decades of office, having posts all across the empire, both east and west. In the west he gave considerable favoritism to Spain in which he granted Latin rights to over three hundred towns and cities, promoting a new era of urbanization throughout the western (i.e. formerly barbarian) provinces. Through the additions he made to the Senate he allowed greater influence of the provinces in the Senate, helping to promote unity in the empire. He also extended the borders of the empire on every front, most of which was done to help strengthen the frontier defenses, one of Vespasian's main goals. The crisis of 69 had wrought havoc on the army. One of the most marked problems had been the support lent by provincial legions to men who supposedly represented the best will of their province. This was mostly caused by the placement of native auxiliary units in the areas they were recruited in, a practice Vespasian stopped. He mixed auxiliary units with men from other areas of the empire or moved the units away from where they were recruited to help stop this. Also, to further reduce the chances of another military coup he broke up the legions, and instead of placing them in singular concentrations broke them up along the border. Perhaps the most important military reform he undertook was the extension of legion recruitment from exclusively Italy to Gaul and Spain, in line with the Romanization of those areas.
Titus (79–81)
Titus, the eldest son of Vespasian, had been groomed to rule. He had served as an effective general under his father, helping to secure the east and eventually taking over the command of Roman armies in Syria and Palestine, quelling the significant Jewish revolt going on at the time. Throughout his father's reign he had been tailored for rule, sharing the consul for several years with his father and receiving the best tutelage. Although there was some trepidation when he took office due to his known dealings with some of the less respectable elements of Roman society, he quickly proved his merit, even recalling many exiled by his father as a show of good faith. However, his short reign was marked by disaster: in 79, Vesuvius erupted in Pompeii, and in 80, a fire decimated much of Rome. His generosity in rebuilding after these tragedies made him very popular. Titus was very proud of his work on the vast amphitheater begun by his father. He held the opening ceremonies in the still unfinished edifice during the year 80, celebrating with a lavish show that featured 100 gladiators and lasted 100 days. Titus died in 81, at the age of 41 of what is presumed to be illness; it was rumored that his brother Domitian murdered him in order to become his successor, although these claims have little merit. Whatever the case, he was greatly mourned and missed.
Domitian (81–96)
The Flavians all had rather poor relations with the senate due to their more autocratic style, however Domitian was the only one who truly created significant problems. His continuous control as consul and censor throughout his rule, the former his father sharing in much the same way of his Julio-Claudian forerunners, the latter having difficulty even obtaining, were unheard of. In addition, he often appeared in full military regalia as an imperator, an affront to the idea of what the Principate-era emperor's power was based upon, the emperor as the princeps. His reputation in the Senate aside, he kept the people of Rome happy through various measures, including donations to every resident of Rome, wild spectacles in the newly finished Colosseum, and continuing the public works projects of his father and brother. He also apparently had the good fiscal sense of his father, because although he spent lavishly his successors came to power with a well endowed treasury. However, during the end of his reign Domitian became extremely paranoid which probably had its initial roots in the treatment he received by his father: although given significant responsibility, he was never trusted with anything important without supervision. This flowered into the severe and perhaps pathological repercussions following the short lived rebellion in 89 of Antonius Saturninus, a governor and commander in Germany. Domitian's paranoia led to a large number of arrests, executions, and seizure of property (which might help explain his ability to spend so lavishly). Eventually it got to the point where even his closest advisers and family members lived in fear, leading them to his murder in 96 orchestrated by his enemies in the Senate, Stephanus (the steward of the deceased Julia Flavia), members of the Pretorian Guard and empress Domitia Longina.
The Adoptive Emperors

"Five Good Emperors" (96–180)
180 The next century came to be known as the period of the "Five Good Emperors", in which the succession was peaceful though not dynastic and the Empire was prosperous. The emperors of the period were Nerva (96–98), Trajan (98–117), Hadrian (117–138), Antoninus Pius (138–161) and Marcus Aurelius (161–180), each being adopted by his predecessor as his successor during the latter's lifetime. While their respective choices of successor were based upon the merits of the individual men they selected, many argue the real reason for the lasting success of the adoptive scheme of succession lay more with the fact that none of them had a natural heir. Under Trajan, the Empire's borders briefly achieved their maximum extension with provinces created in Mesopotamia in 117. From 166, Roman embassies to China, first sent under the reign of Antonius Pius and probably traveling on the southern sea route, are recorded in Chinese historical sources such as the Later Han History.
Commodus (180–192)

Commodus was the son of Marcus Aurelius, making him the first direct successor in a century, breaking the scheme of adoptive successors that had turned out so well. He was co-emperor with his father from 177. When he became sole emperor upon the death of his father in 180, it was at first seen as a hopeful sign by the people of the Roman Empire. Nevertheless, as generous and magnanimous as his father was, Commodus turned out to be just the opposite. Commodus is often thought to have been insane, and he was certainly given to excess. He began his reign by making an unfavorable peace treaty with the Marcomanni, who had been at war with Marcus Aurelius. Commodus also had a passion for gladiatorial combat, which he took so far as to take to the arena himself, dressed as a gladiator. In 190, a part of the city of Rome burned, and Commodus took the opportunity to "re-found" the city of Rome in his own honor, as Colonia Commodiana. The months of the calendar were all renamed in his honor, and the senate was renamed as the Commodian Fortunate Senate. The army became known as the Commodian Army. Commodus was strangled in his sleep in 192, a day before he planned to march into the Senate dressed as a gladiator to take office as a consul. Upon his death, the Senate passed damnatio memoriae on him and restored the proper name to the city of Rome and its institutions. The popular movies The Fall of the Roman Empire (1964) and Gladiator (2000) were loosely based on the career of the emperor Commodus, although they should not be taken as an accurate historical depictions of his life.
Severan dynasty (193–235)
The Severan dynasty includes the increasingly troubled reigns of Septimius Severus (193–211), Caracalla (211–217), Macrinus (217–218), Elagabalus (218–222), and Alexander Severus (222–235). The founder of the dynasty, Lucius Septimius Severus, belonged to a leading native family of Leptis Magna in Africa who allied himself with a prominent Syrian family by his marriage to Julia Domna. Their provincial background and cosmopolitan alliance, eventually giving rise to imperial rulers of Syrian background, Elagabalus and Alexander Severus, testifies to the broad political franchise and economic development of the Roman empire that had been achieved under the Antonines. A generally successful ruler, Septimius Severus cultivated the army's support with substantial remuneration in return for total loyalty to the emperor and substituted equestrian officers for senators in key administrative positions. In this way, he successfully broadened the power base of the imperial administration throughout the empire. Abolishing the regular standing jury courts of Republican times, Septimius Severus was likewise able to transfer additional power to the executive branch of the government, of which he was decidedly the chief representative. Septimius Severus' son, Marcus Aurelius Antoninus — nicknamed Caracalla — removed all legal and political distinction between Italians and provincials, enacting the Constitutio Antoniniana in 212 which extended full Roman citizenship to all free inhabitants of the empire. Caracalla was also responsible for erecting the famous Baths of Caracalla in Rome, their design serving as an architectural model for many subsequent monumental public buildings. Increasingly unstable and autocratic, Caracalla was assassinated by the praetorian prefect Macrinus in 217, who succeeded him briefly as the first emperor not of senatorial rank. The imperial court, however, was dominated by formidable women who arranged the succession of Elagabalus in 218, and Alexander Severus, the last of the dynasty, in 222. In the last phase of the Severan principate, the power of the Senate was somewhat revived and a number of fiscal reforms were enacted. Despite early successes against the Sassanian Empire in the East, Alexander Severus' increasing inability to control the army led eventually to its mutiny and his assassination in 235. The death of Alexander Severus ushered in a subsequent period of soldier-emperors and almost a half-century of civil war and strife.
Crisis of the 3rd Century (235–284)
The Crisis of the 3rd Century is a commonly applied name for the crumbling and near collapse of the Roman Empire between 235 and 284. During this period, Rome was ruled by more than 35 individuals, most of them prominent generals who assumed Imperial power over all or part of the empire, only to lose it by defeat in battle, murder, or death. After nearly 50 years of external invasion, internal civil wars and economic collapse, the Empire was on the verge of ending. A series of tough soldier-emperors saved the empire, but in the process fundamentally changed the Roman Empire. The transitions of this period mark the beginnings of Late Antiquity and the end of Classical Antiquity.
Tetrarchy (285–324)
324 sacked from a Byzantine palace in 1204, Treasury of St Mark's, Venice]] The transition from a single united empire to the later divided Western and Eastern empires was a gradual transformation. In July, 285, Diocletian defeated rival Emperor Carinus and briefly became sole emperor of the Roman Empire. Diocletian saw that the vast Roman Empire was ungovernable by a single emperor in the face of internal pressures and military threats on two fronts. He therefore split the Empire in half along a north-west axis just east of Italy, and created two equal Emperors to rule under the title of Augustus. Diocletian was Augustus of the eastern half, and gave his long time friend Maximian the title of Augustus in the western half. In 293 authority was further divided as each Augustus took a Caesar to aid him in administrative matters, and to provide a line of succession; Galerius became the junior emperor of Diocletian and Constantius Chlorus the junior emperor of Maximian. This constituted what is called the Tetrarchy (in Greek: the leadership of four) by modern scholars. The system allowed the peaceful succession of the Augusti as the Caesar in each half rose up to replace the Augustus and proclaimed a new Caesar. On May 1, 305 Diocletian and Maximian abdicated in favor of their Caesars. Galerius named the two new Caesars: his nephew Maximinus for himself and Flavius Valerius Severus for Constantius. The Tetrarchy would effectively collapse with the death of Constantius Chlorus on July 25 306. Constantius' troops in Eboracum immediately proclaimed his son Constantine an Augustus. In August, 306, Galerius promoted Severus to the position of Augustus. A revolt in Rome supported another claimant to the same title: Maxentius, son of Maximian, who was proclaimed Augustus on October 28, 306. His election was supported by the Praetorian Guard. This left the Empire with five rulers: four Augusti (Galerius, Constantine, Severus and Maxentius) and a Caesar (Maximinus). The year 307 saw the return of Maximian to the role of Augustus alongside his son Maxentius creating a total of six rulers of the Empire. Galerius and Severus campaigned against them in Italy. Severus was killed under command of Maxentius on September 16, 307. The two Augusti of Italy also managed to ally themselves with Constantine by having Constantine marry Fausta, the daughter of Maximian and sister of Maxentius. The end of 307 saw the Empire with four Augusti (Maximian, Galerius, Constantine and Maxentius) and a sole Caesar (Maximinus). The five were briefly joined by another Augustus in 308,
