(born circa 990—died Sept. 4, 1063, Rayy, Iran) Founder of the Seljūq dynasty. He and his brother Chagrï took refuge in Khwārezm in Central Asia after being defeated by Mahsubdotmūd of Ghazna. Later they entered Khorāsān (northeastern Iran), where they gradually built a power base, returning to defeat Mahsubdotmūd's son (1040). Chagrï took over Khorāsān, and Toghrïl prepared to conquer the rest of Iran. In the 1040s he extended his authority to Rayy, Hamadān, and Essubdotfahān, and in 1055 he entered Baghdad, where he had been commissioned by the caliph of the aynAbbāsid dynasty to overthrow the Shīaynite tsubdotimid dynasty. In 1060 Toghrïl crushed a rebellion in Baghdad.
