41 by Gotarzes, chief official of Artabanus.
42 Vardanes recovers throne, owing to Gotarzes’ cruelties. Civil war results.
43 Vardanes captures Seleucia, and Gotarzes retires to Hyrcania.
45 Gotarzes makes unsuccessful attempt to regain throne.
46 Vardanes murdered while hunting. Gotarzes again takes throne.
47 On account of Gotarzes’ misrule, the Parthians ask Claudius to give them Meherdates (Mithridates V) son of Vonones as king.
50 Gotarzes captures Meherdates on his way to Parthia.
51 Death of Gotarzes succeeded by Vonones II, formerly king of Media and probably brother of Artabanus III.
54 Death of Vonones succeeded by his eldest son, Vologases I, who is the son of a concubine; but to compensate his brothers, Vologases puts Pacorus on the throne of Media and Tiridates on that of Armenia—having deposed Radamistus the usurper from the latter country. A son of Vardanes contests the throne with Vologases and apparently has the upper hand for a while.
55 The Romans compel the Parthians to evacuate Armenia.
