Ertuğrul (Ottoman Turkish: ارطغرل, Erṭoġrıl; often with the title Gazi) (died c. 1280) was the father of Osman I, the founder of theOttoman Empire. While his historicity is proven by coins minted by Osman I which identify Ertuğrul as his father, almost nothing can be known for certain about his life or activities. According to Ottoman mythic tradition, he was the son of Suleiman Shah, leader of the Kayı tribe of Oghuz Turks, who fled from eastern Iran to Anatolia to escape the Mongol Conquests. According to this legend, after the death of his father, Ertuğrul and his followers entered the service of the Seljuks of Rum, for which he was rewarded with dominion over the town of Söğüt on the frontier with the Byzantine Empire. This set off the chain of events that would ultimately lead to the founding of the Ottoman Empire. Like his son, Osman, and his future descendants, Ertuğrul is often referred to as aGhazi, a heroic champion fighter for the cause of Islam.
According to Ottoman tradition, Ertuğrul was chief of the Kayı tribe of Oghuz Turks, as a result of his assistance to the Seljuksagainst the Byzantines. Ertuğrul was granted lands in Karaca Dağ, a mountainous area near Angora (now Ankara), 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 together with the surrounding lands. That village, where he later died, became the Ottoman capital under his son Osman I. Ertuğrul had two other sons, Saru Batu Savcı Bey and Gündüz Bey.
In the 19th century, the Ottoman Navy frigate Ertuğrul was named in his honor. The Ertuğrul Gazi Mosque in Asgabat, Turkmenistan is also named in his honor. In the TV seriesDiriliş: Ertuğrul, Ertuğrul is portrayed by Turkish actor Engin Altan Düzyatan.
