Tughril (full name: Rukn ad-Dunya wa ad-Din Abu Talib Muhammad Toghrul-Beg ibn Mikail) also spelled Toghrul I, Tugril, Toghril, Tugrul or Toghrïl Beg; (b.

990 - d. September 4, 1063) is the founder of the Seljuq Empire, and the first sultan of this empire from 1037 to 1063.

Tughril unites the Turkomen warriors of the Great Eurasian Steppes into a confederacy of tribes, who trace their ancestry to a single ancestor named Seljuq, and lead them in conquest of eastern Iran.

He will later establish the Seljuq Sultanate after conquering Persia and retaking the Abbasid Capital of Baghdad from the Buyid Dynasty in 1055.

Tughril relegates the Abbasid Caliphs to state figureheads and takes command of the caliphate's armies in military offensives against the Byzantine Empire and the Fatimid Caliphate in an effort to expand his empire's borders and unite the Islamic world.
