Turgut Alp

[3][1] After the establishment of the Empire, he became one of its military commanders, serving Osman I, as well as his son, Orhan Gazi.

[4] During the early Ottoman Conquests in the reign of Osman I, Turgut Alp was sent to Angelacoma (present-day İnegöl) and he conquered the area.

[5][6] This area consisting some villages, was given to him by Osman I and his territory was called Turgut-ili (Province of Turgut).

[7][8][9] During the Siege of Bursa, Turgut Alp, along with Osman's warrior Mihal Gazi, participated in the conquest of Atranos Castle (later known as Orhaneli) in 1325, which played a key role in leading to the Ottoman conquest of Bursa during the reign of Sultan Orhan.

[13] In 1877, during the Russo-Turkish War (1877-1878), a city was founded and named "Turgutalp" after him in the then-Ottoman Empire.
