Ertuğrul
Ottoman ruler, father of Osman I
Ertuğrul or Ertuğrul Ghazi (Ottoman Turkish: ارطغرل, romanized: Erṭoġrıl; died c. 1280/1281) was a 13th-century uch bey (marcher-lord), who was the father of Osman I. Little is known about Ertuğrul's life. According to Ottoman tradition, he was the son of Suleyman Shah, the leader of the Kayı tribe (a claim which has come under criticism from many historians) of the Oghuz Turks (then known as Turkomans), which fled from western Central Asia to Anatolia to escape the Mongol conquests; but according to contemporary numinastic evidence, he was the son of Gündüz Alp. According to the legend, after the death of his father, Ertuğrul and his followers entered the service of the Sultanate 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.
Biography
Nothing is known for certain about Ertuğrul's life, except that he was the father of Osman. As a result, historians are compelled to rely on stories written about him by the Ottomans more than a century later, which are of questionable accuracy.
According to the sources written c. 100–150 years after the establishment of the Ottoman state, Ertuğrul's lineage is traced to Noah, through Oghuz Khagan. Ottoman historian and ambassador to the Qara Qoyunlu, Şükrullah states that Ertuğrul's lineage goes to Gökalp, a son of Oghuz Khagan. The author states that the information was shown during a court of Jahan Shah, from a book written in Mongolian script.
