Kingdom of Vaspurakan (Վասպուրական) was one of the Medieval Armenian Kingdoms. This kingdom's territory was almost equal with the Greater Armenia Vaspurakan province territory. Located in what is now called eastern Turkey (Western Armenia) and northwestern Iran, the region is considered to be the cradle of Armenian civilization.
During most of its history it was ruled by the Ardzruni dynasty, which first managed to create a principality in the area. At its greatest extent Vaspurakan comprised the lands between Lake Van and Lake Urmia (also known as Kaputan) in 908. During this time they were under the sovereignty of the Bagratuni Kingdom of Ani.
