Ertuğrul (Ottoman Turkish: ارطغرل, often with the title Gazi) (1188/1191/1198 – 3 May 1281) was the father of Osman I, the founder of the Ottoman Empire. He was the leader of the Kayı clan of the Oghuz Turks. When arriving in Anatolia from Merv (Turkmenistan) with his 400 horsemen to aid the Seljuks of Rum against the Byzantines, Ertuğrul 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 a Ghazi, a heroic champion fighter for the cause of Islam.
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 (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 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.
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 series Diriliş: Ertuğrul, Ertuğrul is portrayed by Turkish actor Engin Altan Düzyatan.
