Arsaces I of Armenia

Arsaces I of Armenia, also known as Arsaces I, Arshak I and Arsak (ruled 35 AD) was a Parthian prince who was king of Armenia during 35 AD.

Arsaces I was the first-born son of King Artabanus II of Parthia by a wife whose name is unknown. After the death of the Roman client king of Armenia, Artaxias III, in 34 AD, Artabanus II decided to put his son on the Armenian throne. Artabanus II made Arsaces I king of Armenia and Arsaces was accompanied to Armenia with a strong army. Roman emperor Tiberius, refused to accept Arsaces I as king. So Tiberius, with the support of King Pharasmanes I of Iberia, appointed Pharasmanes' brother, Mithridates, to be the new Roman client Armenian king.

Less than a year into his reign, Arsaces I was poisoned by his servants who had been bribed to kill him. After Arsaces I died, Artabanus II put another of his sons, Orodes, on the Armenian throne. Orodes soon had to face Mithridates in a military campaign.
