アルプ・アルスラーン
Alp Arslan divided the conquered eastern portions of the Byzantine empire among his Turcoman generals, with each ruled as a hereditary beylik, under overall sovereignty of the Seljuq Empire. Alp Arslan gave the region around Lake Van to his commander Sökmen el-Kutbî, who set up his capital at Ahlat on the western side of the lake. The dynasty of Shah-Armens, also known as "Sökmenler", ruled this area from 1085 to 1192.
