Arsacid dynasty

Continuation of Roman hostilities and Parthian decline

After the Iberian king Pharasmanes I had his son Rhadamistus (r. 51–55 AD) invade Armenia to depose the Roman client king Mithridates, Vologases I of Parthia (r. c. 51–77 AD) planned to invade and place his brother, the later Tiridates I of Armenia, on the throne. Rhadamistus was eventually driven from power, and, beginning with the reign of Tiridates, Parthia would retain firm control over Armenia—with brief interruptions—through the Arsacid dynasty of Armenia. Even after the fall of the Parthian Empire, the Arsacid line lived on through the Armenian kings. However, not only did the Arsacid line continue through the Armenians, it also continued through the Georgian kings with the Arsacid dynasty of Iberia, and for many centuries afterwards in Caucasian Albania through the Arsacid dynasty of Caucasian Albania.
