Yiwa (tribe)

Yiwa (Yıva, Yıva, Ywa) was one of the 24 ancient Oghuz (Turkoman) tribes. The Yiwa tribe belonged to the tribe of Dengiz Khan, the youngest son of Oghuz Khagan.

Part of the Yiwa, led by Suleyman Shah, moved from Central Asia to Western Iran and the upper reaches of Tigris and Euphrates in the 13th century. The capital of Suleyman Shah became the city of Bahar (near Hamadan). Suleyman Shah led the defense of Baghdad against the Mongols of Hulagu and was defeated.
