The Arsacid Dynasty or (sometimes called the Arshakuni Dynasty) ruled the Kingdom of Armenia from 54 to 428. They started as a branch of the Parthian Arsacids but became a distinctly Armenian dynasty later on. Armenia was between the Parthian and Roman Empires and both were trying to control it. Arsacid Kings reigned intermittently throughout the chaotic years after the fall of the Artaxiad Dynasty until 62 when Tiridates I of Armenia secured Arsacid rule in Armenia.
