[7] Vologases felt his invasion was justified due to the recent usurpation of the Armenian throne by the Iberian prince Rhadamistus, which he saw as a violation of the former settlement made between the Parthians and Romans regarding Armenia.

[2] Lack of resources and a winter epidemic forced Vologases to withdraw his troops from Armenia, allowing Rhadamistus to come back and punish locals as traitors; they shortly revolted and helped Tiridates restore his authority.

[8] Rhadamistus himself returned to Iberia and was soon put to death by his father Pharasmanes I for having plotted against the royal power in order to prove his loyalty to Rome.

[10] Vologases was unable to aid his brother, due to the rebellion of his son Vardanes II and subsequently a revolt in the eastern Parthian province of Hyrcania.

[10] He also emboldened the Roman client-kings Antiochus IV of Commagene, Pharasmanes I, and the Moschi tribes to attack outlying areas of Armenia.

[15] The new ruler, protected by a strong Roman force, became bold and started in 61 attacking the border areas of Adiabene, a vassal kingdom of the Parthians.

[15][16] The Adiabenian king, Monobazos, including Tiridates, protested in front of the entire Parthian court, complaining that Vologases did not do enough to protect his subjects.

The command of the troops was returned to Corbulo, who, the following year, led a strong army into Melitene and beyond into Armenia, eliminating all of the regional governors he suspected were pro-Parthian.

[24] Tiridates I was recognized as the vassal king of Armenia; a Roman garrison would remain in the country permanently, in Sophene while Artaxata would be reconstructed.

Corbulo left his son-in-law Lucius Annius Vinicianus to accompany Tiridates I to Rome in order to attest his own fidelity to Nero.

"[25] However, Vologases I was still satisfied with this result and honored the memory of Nero,[26] though he stood in good relations with Vespasian also, to whom he offered an army of 40,000 horse archers during the Jewish Revolt.

[27] Soon afterwards the Alans, a great nomadic tribe beyond the Caucasus, invaded Atropatene and Armenia; Vologases I applied in vain for help to Vespasian, but did not achieve any decisive result.

[30] Vologases sought to accomplish the goal of Artabanus II, by attempting to establish a long and structured trade-route that spanned through East Asia, India and the coast of the Mediterranean Sea.
