was disputed by his younger brother Orodes who was previously overthrown by Zeno. Tiberius quickly concentrated more forces on the Roman frontier and once again after a decade of peace, Armenia was to become the theater of bitter warfare between the two greatest powers of the known world for the next twenty-five years. Tiberius, sent an Iberian named Mithridates, who claimed to be of Arsacid blood. Mithridates successfully subjugated Armenia to the Roman rule and deposed Arsaces inflicting huge devastation to the country. Surprisingly, Mithridates was summoned back to Rome where he was kept a prisoner, and Armenia was given back to Artabanus II who gave the throne to his younger son Orodes. Another civil war erupted in Parthia upon Artabanus II's death. In the meantime Mithridates was put back on the Armenian throne, with the help of his brother, Pharasmanes I, and Roman troops. Civil war continued in Parthia for several years with Gotarzes eventually seizing the throne in 45. In 51 Mithridates’ nephew Rhadamistus (a.k.a. Ghadam) invaded Armenia and killed his uncle. The governor of Cappadocia, Julius Pailinus, decided to conquer Armenia but he settled with the crowning of Radamistus who generously rewarded him. The current Parthian King Vologases I, saw an opportunity, invaded Armenia and succeeded in forcing the Iberians to withdraw from Armenia.

After regaining power, according to Tacitus, the Iberian was so cruel that the Armenians stormed the palace and forced Radamistus out of the country and Vologases I got the opportunity to install his brother Tiridates on the throne. Between Rome and Parthia Unhappy with the growing Parthian influence at their doorstep, Roman emperor Nero sent General Gnaeus Domitius Corbulo with a large army to the east in order to install Roman client kings (see Roman–Parthian War of 58–63). After Tiridates I escaped, Roman client king Tigranes VI was installed and in 61 he invaded the Kingdom of Adiabene, which was one of the Parthian vassal kingdoms. Vologases I considered this as an act of aggression from Rome and restarted a campaign to restore Tiridates I to the Armenian throne. In the following Battle of Rhandeia in 62, command of the Roman troops was again entrusted to Corbulo, who marched into Armenia and set a camp in Rhandeia, where he
