The 80s was a decade that ran from January 1, AD 80, to December 31, AD 89.
As the decade began, the Parthian Empire was in a phase of division until Pacorus II managed to consolidate his rule, eliminating the two rival contenders for his throne: Vologases II in AD 80 and Artabanus III in AD 81. Domitian became Roman emperor in AD 81: The military campaigns undertaken during his reign were generally defensive in nature, as the Emperor rejected the idea of expansionist warfare. His most significant military contribution was the development of the Limes Germanicus, which encompassed a vast network of roads, forts and watchtowers constructed along the Rhine river to defend the Empire. Nevertheless, several important wars were fought in Gaul, against the Chatti, and across the Danube frontier against the Suebi, the Sarmatians, and the Dacians (see Domitian's Dacian War). In northern Britain, the Romans defeated local tribes in the Battle of Mons Graupius (AD 83). In China, the Han–Xiongnu War continued, with the Battle of the Altai Mountains (AD 89) bringing the Northern Xiongnu to the brink of collapse. The death of Emperor Zhang of Hanended a golden age.
In spring of AD 80, a fire broke out in Rome and burned large parts of the city for three days and three nights. Although the extent of the damage was not as disastrous as during the Great Fire of 64 and crucially spared the many districts of insulae, Cassius Dio records a long list of important public buildings that were destroyed, including Agrippa's Pantheon, the Temple of Jupiter, the Diribitorium, parts of the Theatre of Pompey, and the Saepta Julia among others. Emperor Titus personally compensated for the damaged regions. According to Suetonius, a plague also broke out during the fire. The nature of the disease, however, and the death toll are unknown.
Some 30,000 Asian tribesmen migrate from the steppes to the west with 40,000 horses and 100,000 cattle, joining with Iranian tribesmen and with Mongols from the Siberian forests to form a group that will be known in Europe as the Huns.
King Pasa becomes ruler of the Korean kingdom of Silla.[4]
September 14 – Domitian succeeds his brother Titus as emperor. Domitian is not a soldier like his two predecessors, and his administration is directed towards the reinforcement of a monarchy. By taking the title of Dominus ("lord"), he scandalizes the senatorial aristocracy. Romanisation progresses in the provinces, and life in the cities is greatly improved. Many provincials – Spanish, Gallic, and African – become Senators.
Emperor Domitian recalls Agricola back to Rome, where he is rewarded with a triumph and the governorship of the Roman province of Africa, but he declines it.[citation needed]
The construction of the limes, a line of Roman fortifications from the Rhine to the Danube, has begun.[8]
Through his election as consul for ten years and censor for life, Domitian openly subordinates the republican aspect of the state to the monarchical.[citation needed]
Domitian increases the troops' pay by one third, thus securing their loyalty.[9]
Domitian appoints himself censor for life, which gives him the right to control the Senate. His totalitarian tendencies put the senatorial aristocracy firmly in opposition to him.
First Battle of Tapae: Roman legions face disaster in Dacia, when Roman general Cornelius Fuscus launches a powerful offensive that becomes a failure. Encircled in the valley of Timi, he dies along with his entire army. Rome must pay tribute to the Dacians in exchange for a vague recognition of Rome's importance.
Emperor Han Zhangdi dies at age 31 after a 13-year reign in which Chinese military forces have become powerful enough to march against tribes who threaten their northern and western borders. Having used intrigue as well as armed might to achieve his ends, Zhangdi and his General Ban Chao have reestablished Chinese influence in Inner Asia, but court eunuchs have increased their power during the emperor's reign. Zhangdi is succeeded by his 9-year-old son Zhao, who will reign until 105 as emperor Han Hedi, but he will be a virtual pawn of Empress Dou (adoptive mother) and scheming courtiers who will effectively rule the Chinese Empire.
Last year (4th) of yuanhe era and start of zhanghe era of the Chinese Eastern Han dynasty.
