The Arsacid dynasty, called the Arshakuni () in Armenian, ruled the Kingdom of Armenia from 12 to 428. The dynasty was 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, brother of the Parthian king Vologases I, secured Arsacid rule in Armenia as a client king of Rome. However, he did not succeed in establishing his line on the throne, and various princes of different Arsacid lineages ruled until the accession of Vologases II, who succeeded in establishing his own line on the Armenian throne, which ruled the kingdom until its abolishment by the Sasanian Empire in 428. Two of the most notable events under Arsacid rule in Armenian history were the conversion of Armenia to Christianity by Gregory the Illuminator and Tiridates III in 301/314 and the creation of the Armenian alphabet by Mesrop Mashtots in c. 405. In contrast to the more Hellenic-influenced Artaxiads, the reign of the Arsacids of Armenia was marked by greater Iranian influence in the country. Early Arsacids The first appearance of an Arsacid on the Armenian throne occurred in 12 when the Parthian king Vonones I was exiled from Parthia due to his pro-Roman policies and Occidental manners. Vonones I briefly acquired the Armenian throne with Roman consent, but Artabanus II, incorrectly known as Artabanus III in older scholarship, demanded his deposition, and as Emperor Augustus did not wish to begin a war with the Parthians he deposed Vonones I and sent him to Syria. Soon after the deposition of Vonones I, Artabanus II installed his son Orodes on the Armenian throne. Emperor Tiberius had no intention of giving up the buffer states of the Eastern frontier and sent his nephew and heir Germanicus to the East. Germanicus concluded a treaty with Artabanus II, in which he was recognized as king and friend of the Romans. Armenia was given in 18 to Zeno, son of Polemon I of Pontus, who assumed the Iranian name Artaxias (a.k.a. Zeno-Artaxias). The Parthians under Artabanus II were too distracted by internal strife to oppose the Roman-appointed King. Zeno's reign was remarkably peaceful in Armenian history. After Zeno's death in 36, Artabanus II decided to reinstate an Arsacid over the Armenian throne, choosing his eldest son Arsaces I as a suitable candidate, but his succession to the Armenian throne
