Ertuğrul was born in Ahlat. In 1230, he succeeded as chief of the Kayı tribe of the Oghuz Turks, as a result of his assistance to the Seljuks against the Byzantines. Ertuğrul was granted lands in Karaca Dağ, a mountainous area near Angora, by Ala ad-Din Kay Qubadh I, the Seljuk Sultan of Rûm. One account indicates that the Seljuk leader's rationale for granting Ertuğrul land was for Ertuğrul to repel any hostile incursion from the Byzantines or other adversary. Later, he received the village of Sögüt which he conquered in 1231 together with the surrounding lands. That village, where he later died, became the Ottoman capital in 1299 under his son Osman I. Ertuğrul had two other sons, Saru Batu Savcı Bey and Gündüz Bey.
