Located in what is now southeastern Turkey and northwestern Iran, the region is considered to be the cradle of Armenian civilization.[6] Armenologist Heinrich Hübschmann considered it likely that the name originated as a shortening of the koghmn Vaspurakan Gndin ("land of the army/troop of nobles") mentioned by the 7th-century historian Sebeos.[8] Later Armenian historians (e.g. Łewond, Hovhannes Draskhanakerttsi, Tovma Artsruni) refer to the province more frequently, especially after the emergence of the Artsruni-ruled principality in Vaspurakan.In 1021, Seneqerim Ardzruni gave Vaspurakan to the Byzantine Empire, receiving estates in Sebasteia and surroundings in exchange.In the beginning of the 13th century, part of Vaspurakan was liberated by the Zakarians, but was then conquered by the Mongols, Seljuks, Kara Koyunlu, Iranian Safavids, and then by the Ottoman Turks (though Nader Shah regained it during his short lived Afsharid dynasty).
