The Arsacid dynasty known natively as the Arshakuni dynasty ( Aršakuni) ruled the Kingdom of Armenia from 54 to 428. They are a branch of the Arsacid dynasty of Parthia. Arsacid Kings reigned intermittently throughout the chaotic years following the fall of the Artaxiad Dynasty until 62 when Tiridates I secured Arsacid dynasty of Parthia rule in Armenia. An independent line of Kings was established by Vologases II (Vagharsh II) in 180. Two of the most notable events under Arsacid rule in Armenian history were the conversion of Armenia to Christianity by Gregory the Illuminator in 301 and the creation of the Armenian alphabet by Saint Mesrob in c. 406.
