Gongju becomes the capital of Baekje, and is threatened by Goguryeo, which conquers the Han River valley.

The continental invaders of Britain have established the Jutish kingdom of Kent by 475.

A popular revolt against the emperor starts within the capital in 475.

The uprising receives military support by Theodoric Strabo, Illus and Armatus and succeeds in taking control of Constantinople.

Verina persuades her son-in-law to leave the city.

Zeno flees to his native lands, bringing with him some of the Isaurians living in Constantinople, and the imperial treasury.

Basiliscus is now acclaimed as Augustus on January 9, 475, at the Hebdomon palace, by the palace ministers and the Senate.

The mob of Constantinople takes its revenge, killing almost all of the Isaurians left in the city.

Basilicius supports the Monophysites, who gain control of the key sees of Alexandria, Antioch, and Jerusalem.

However Basiliscus soon manages to estrange himself from most of his key collaborators.

Nepos, a year after ascending the Western throne, is obliged to recognize the independence of the Visigothic kingdom centered near present Toulouse, France.

Orestes, born an aristocrat of Pannonia Savia, is probably at least partly of Germanic descent.

He was the son of Tatulus, a pagan, and son-in-law to Romulus, who had served as comes in the Western Roman Empire.

After Pannonia was ceded to Attila the Hun, Orestes had joined Attila's court, reaching high position as a secretary (notarius) in 449 and 452.

In 449 Orestes had been sent by Attila twice to Constantinople as envoy to Emperor Theodosius II.

In 475, Orestes had been appointed magister militum and patricius by Julius Nepos.

This proves to be a mistake on the part of Nepos.

By August 28, 475, Orestes, at the head of the foederati, manages to take control of the government in Ravenna, which has served as the capital of the Western Roman Empire since 402.

Julius Nepos flees without a fight to Dalmatia, where he will continue to reign until his assassination in 480.

Orestes, with the emperor far away, on October 31 elevates his son Romulus to the rank of Augustus.

Thus he is known as Romulus Augustulus, meaning "little Augustus", as this last Western Roman emperor is only a twelve-year-old boy.

The new administration is not recognized by the rival Eastern Roman Emperors Zeno and Basiliscus, who still consider Julius Nepos to be their legitimate partner in the administration of the Empire, but as they are engaged in a civil war with each other, neither emperor is about to oppose Orestes in battle.

Euric’s forces have built fortifications at several key locations throughout the empire (those at the ancient city of Carcassonne in southwestern France are among the finest remains of medieval ramparts in Europe).

Patricius, the magister officiorum and lover of Verina, had been executed to prevent her aspirations to elevate him to the throne.

As a consequence, Verina later intrigues against Basiliscus, because of her lover's execution.

Theodoric and Armatus are promoted to magister millitum and magister militum praesentialis and are vying for authority.

Finally, the support of Illus is most likely wavering, given the massacre of the Isaurians allowed by Basiliscus.

Basiliscus has reigned at Constantinople for twenty months, but his religious beliefs make him highly unpopular.

As emperor, he has stirred up discontent because he favors the Monophysite heresy, which holds that the human and divine elements in Christ's nature were inseparable.

During his reign, a disastrous fire in Constantinople destroys much of the city along with many Greek works of art.

With the help of Illus and Armatus, who change their allegiance, Zeno returns to besiege Constantinople in August 476.

The leader of the Pannonian Goths, Theodoric the Amal (later known as Theodoric the Great) had allied to Zeno, and would have attacked Basiliscus and his Thracian Goth foederati led by Theodoric Strabo, receiving, in exchange, the title of magister militum held by Strabo and the payments previously given to the Thracian Goths.

It has been suggested that Constantinople was defenseless during Zeno's siege because the Magister Militum Strabo had moved north to counter this menace.

The Senate opens the gates of the city to the Isaurian, allowing the deposed emperor to resume the throne.

Ariadne is still his Empress consort.

Basiliscus is exiled to a fortress in Cappadocia, where he will die from starvation.

Orestes is free to issue new solidi in the mints of Arles, Milan, Ravenna and Rome, enabling him to pay the barbarian mercenaries who constitute most of the Roman Army at this time.

However, Orestes denies the demands of Heruli, Scirian and Turcilingi mercenaries to be granted Italian lands in which to settle.

Before he overthrew Nepos, the Roman general had promised his barbarian soldiers a third of Italian territory in exchange for assisting with the deposition of the emperor.

After being turned down by Orestes, the dissatisfied mercenaries revolt under the Germanic chieftain Odoacer, whom they declare to be their king on August 23, 476.

Odoacer leads his tribesmen against their former employer, ravaging every town and village in northern Italy and meeting little resistance.

Orestes flees to the city of Pavia, where the city's bishop gives him sanctuary within the city walls.

Despite the protection he receives from the bishop, Orestes is forced to flee for his life when Odoacer and his men break through the city defenses and ravage the church, stealing all the money that the bishop had collected for the poor and razing many of the city buildings to the ground.
