During the reign of the
Arsacid dynasty over Armenia, the Artsrunis ruled the princely estates of Greater and Lesser Aghbak in
Vaspurakan (around modern
Başkale, Turkey), southeast of
Lake Van, gradually annexing the surrounding territory. In the middle of the 4th century the family was deposed. Chavash survived, and recovered power. In 369 the state was led by
Meruzhan Artsruni who guided
Persian troops to Armenia, exchanged Christianity for
Mazdaism, and defeated the General (
sparapet)
Mamikonian. The latter recovered power soon after, however, and Meruzhan was killed. in the vine-scroll relief on the eastern façade of the

Rshtuni, Teruni of
Daroynk (before a possession of the
Bagratuni) and ruled the regions of Maku, Artaz, Great Zab Valley and Van river. In the same 8th century, the
Bagratid dynasty, re-established the monarch of Armenia, and the Artsrunis were "among its most powerful vassals and rivals". When the territory of historical Armenia was, about a century later, succeeded by several subkingdoms (each of whom were rule by "lesser princes"), the area of
Vaspurakan came to be ruled in by the Artsrunis, who, in 908, received their investiture from their
Abbasid suzerains. Thus, Khatcḥik-Gagik II Artsruni was the first of the Artsrunis to rule Vaspurakan under Abbasid suzerainty.
Gagik I of Vaspurakan claimed the title of "
King of Armenia" from the
Bagratuni dynasty until his death in 936 or 943. In the beginning of the 11th century, the Artsruni settled westwards in Cappadocia, retreating from eastern invaders. In 1021,
Senekerim-Hovhannes of Vaspurakan was given
Sebaste,
Evdokia, and possibly
Amasia as fiefdom from the Byzantine emperor
Basil II in return for his entire kingdom. He and 14,000 of his retainers settled in the
Theme of Sebasteia, while the Kingdom of Vaspurakan became the Byzantine
theme of Vasprakania, which lasted for fifty years until 1071. ==Cultural legacy==
