Abdülhamid I, Abdul Hamid I or Abd Al-Hamid I (Ottoman Turkish: عبد الحميد اول, `Abdü’l-Ḥamīd-i evvel; Turkish: Birinci Abdülhamit; 20 March 1725 – 7 April 1789) was the 27th Sultan of the Ottoman Empire, reigning over the Ottoman Empire from 1774 to 1789.
Birth and early life
He was born in Constantinople, a younger son of Sultan Ahmed III(reigned 1703–1730) by his consort Rabia Şermi Sultan. Ahmed III abdicated in favor of his nephew Mahmud I, who was succeeded by his brother Osman III, and Osman by Ahmed's elder son Mustafa III.
As a potential heir to the throne, Abdül Hamid was imprisoned in comfort by his cousins and older brother, as was customary. This lasted until 1767. During this period, he received his early education from his mother Rabia Şermi, who taught him history and calligraphy.
When his brother Mustafa III died, Abdül Hamid succeeded him on 21 January 1774.
