Ïnanch Sonqur (Turkic) (in Turkish: İnanç Sankur) or Husam al-Din Sunqur Inanj (in Persian: حسام الدین سنقر اینانج) (died 1169) was the Seljuk amir of Ray from 1160 at the latest until his death.
After the death of Sultan Muhammad ibn Mahmud in 1159, the amirs of the surrounding provinces disagreed on who should succeed him.
[3] For the duration of Suleiman Shah's reign Ïnanch lent him support, but the sultan's incompetence eventually led the amirs to overthrow him and ask the Atabeg of Azerbaijan, Shams al-Din Eldigüz, to replace him with Arslan.
[3] Arslan, however, ran into problems of his own, and eventually Ïnanch and a coalition of other amirs revolted and marched against Hamadan.
[4] Ïnanch invaded the area around Qazvin and Zanjan in 1166/7, but was unable to make any headway against the Seljuks or Eldigüz, and the loosely disciplined Khwarezmian troops were hated by the local people.
