Арташес I
In 189 BC, Nakhchivan became part of the new Kingdom of Armenia established by Artaxias I. Within the kingdom, the region of present-day Nakhchivan was part of the Ayrarat, Vaspurakan and Syunik provinces. According to the early medieval Armenian historian Movses Khorenatsi, from the 3rd to 2nd centuries, the region belonged to the Muratsyan "nakharar" family but after disputes with central power, King Artavazd I massacred the family and seized the lands and formally attached it to the kingdom. The area's status as a major trade center allowed it to prosper; as a result, many foreign powers coveted it. According to the Armenian historian Faustus of Byzantium (5th century), when the Sassanid Persians invaded Armenia, Sassanid King Shapur II (310–380) removed 2,000 Armenian and 16,000 Jewish families in 360–370. In 428, the Armenian Arshakuni monarchy was abolished and Nakhchivan was annexed by Sassanid Persia. In 623, possession of the region passed to the Byzantine Empire but was soon left to its own rule. Sebeos referred to the area as Tachkastan.
