The Great Seljuk Empire, a Sunni Muslim empire based on the Turko -Iranian tradition established by the Kinik tribe of the Oghuz Turks in the Middle Ages .
He controlled a wide area from the Hindu Kush Mountains to Western Anatolia and from Central Asia to the Persian Gulf . After gaining power in their homeland near the Aral Lake , the Seljuks, who first conquered Khorasan , moved from here towards inland Iran and then It took the cities in Anatolia under control.



Great Seljuk Empire was established by Tuğrul Bey (1016-63) in 1037. Selçuk Bey , whose grandfather raised Tuğrul and held high office in the state of Oğuz Yabgu , gave his name to both the dynasty that ruled the country and the empire. Shortly after the state was established, it consolidated the fragmented political map of the Islamic world lacking central authority and later played a key role in the first and second Crusades .
