The Seljuk Empire, or the Great Seljuk Empire, was a high medieval, Turko-Persian empire established and ruled by the Qïnïq branch of Oghuz Turks. The empire spanned a total area of 3.9 million square kilometres from Anatolia and the Levant in the west to the Hindu Kush in the east, and from Central Asia in the north to the Persian Gulf in the south, and it spanned the time period 1037–1308, though Seljuk rule beyond the Anatolian peninsula ended in 1194.
