Abu Talib Muhammad Tughril ibn Mika'il (Persian: ابوطالبْ محمد طغرل بن میکائیل), better known as Tughril (طغرل / طغریل; also spelled Toghril / Tughrul), was a Turkoman chieftain, who founded the Seljuk Empire, ruling from 1037 to 1063.
Tughril united many Turkoman warriors of the Central Asian steppes into a confederacy of tribes and led them in conquest of Khorasan and eastern Persia. He would later establish the Seljuk Sultanate after conquering Persia and taking the Abbasid capital of Baghdad from the Buyids in 1055. Tughril relegated the Abbasid Caliphs to state figureheads and took command of the caliphate's armies in military offensives against the Byzantine Empire and the Fatimids in an effort to expand his empire's borders and unite the Islamic world.
