Corbulo

Corbulo was appointed governor of Cappadocia and Galatia with command against the Parthians in Armenia. He reorganized the Roman army, restored discipline, and captured the Armenian capital Artaxata, installing a Roman client king.

Corbulo captured the Armenian city of Tigranocerta after a siege. The city surrendered without a major battle. Corbulo then crowned Tigranes VI as king of Armenia, a Roman client, solidifying Roman influence in the region.

After the Parthians reasserted control over Armenia, Corbulo was ordered to withdraw. He negotiated a compromise with the Parthian king Vologases I, agreeing that a Parthian prince, Tiridates, would rule Armenia as a Roman client, ending the war.

Nero, suspicious of Corbulo's popularity and military success, summoned him to Greece and ordered his execution. Corbulo was forced to commit suicide. His death removed a potential rival but also a capable general from the Roman command.
