Emperor Zeno officially dissolves the east/west co-emperorship, ruling as the first sole emperor of Rome in 85 years. The position of emperor is never again divided.
December 9 – Odoacer occupies Dalmatia and prosecutes Nepos's killers. He later establishes his political power with the co-operation of the Roman Senate.
Syagrius, ruler of Domain of Soissons, manages to maintain the Roman authority in northern Gaul. He defends his "kingdom" against the neighbouring Salian Franks.
Emperor Zeno promulgates an Edict of Union (Henotikon), in an unsuccessful effort to soften the decision made at the Council of Chalcedon (451), and resolve differences between the Eastern and Western Churches. Zeno wishes to placate the Monophysite churches of Egypt, Palestine and Syria for political reasons.
March 10 – Pope Simplicius dies at Rome after a 15-year reign, and is succeeded by Felix III as the 48th pope; Rome is without a pope for 10 days in the interim.[4] Felix III is a widower with two children.[5][6]
Zeno signs a peace treaty with Theodoric the Great. He appoints him to magister militum and becomes a consul. The Eastern Empire is saved by diplomatic negotiations, and the imperial army is strengthened behind the walls of Constantinople.
December 23 – Huneric dies and is succeeded by his nephew Gunthamund, who becomes king of the Vandals. During his reign the Catholics are free from persecutions and he stabilises the kingdom's economy.
The Hephthalites (White Huns) invade Persia. King Peroz I gathers an army of 50,000-100,000 men, and places his brother Balash at the head of the government in Ctesiphon. At the Battle of Herat, the Persians are ambushed and defeated. Peroz I is killed, his body is with dignity returned and buried with full honors. Balash is crowned and becomes king of Persia.
Emperor Xiaowen institutes an "equal-field" system of agriculture (juntian), assigning each peasant family about 19 acres (140 mu) of land. The land will be part minority divided by the farmer to be kept indefinitely and rest will revert to the state if the farmer dies or retires. The population is then divided by each other with the role of supervising one another. The result of this reform is that farmers mostly did not sell their holdings to large landowners. This provided the fiscal basis for the formation of the Sui and Tang dynasties.[9]
Emperor Zeno regains power from the usurper Leontius and the Isaurian patrician Illus, who are captured and executed, ending a 4-year rebellion (see 484).
Among the peoples who live on the south bank of the Danube in Noricum ripense and who are de facto ruled by the Rugii, whose empire has its centre near Krems on the north bank, are Romii who had been evacuated earlier from Danube settlements above the River Enns. They include members of the Severinconvent. Because some of the Rugii want to fight for East Rome against Odoacer, they destroy the Rugian Empire and allow the Romii to be evacuated to Italy by his brother, Hunulf, in order to prevent the re-establishment of the Rugian Empire by a surviving prince. The northern Danubian Limes of the Roman Empire are effectively abandoned. Even the relics of Severinus of Noricum are carried with them.
August 28 – After crossing the Julian Alps, the Ostrogoths defeat the overwhelming forces of Odoacer at the Battle of Isonzo (near Roman Aquileia or modern Soča) and enter Italy. This date is subsequently used by Theodoric to establish a 30-year statute of limitations (tricennium) ending on 28 August 519, after which any unlawful seizure of land during this period can no longer be contested.
