Ertugrul was the father of Osman (the founder of the Ottoman Empire). Ertugrul followed his father guidance to stand with justice and Allah’s rule. He was an ambitious man who live without fear of death. He was always ready to embrace death for his people. He was constantly engaged in various wars. He was in a war with the Crusaders on one side, the Byzantines on another side and the brutally expanding Mongols who killed a lot of Turks on another side.
As a result of Kayi tribe assistance to the Seljuks against the Byzantines, Ertuğrul was granted lands in Karaca Dağ by Kayqubad I, the Seljuk Sultan of Rum. One account indicates that the Seljuk leader’s rationale for granting Ertuğrul land was for Ertuğrul to repel crusade from the Byzantines.
