Mahmud II (Ottoman Turkish: محمود ثانى Mahmud-u sānī, محمود عدلى Mahmud-u Âdlî) (Turkish: II. Mahmud) (20 July 1789 – 1 July 1839) was the 30th Sultan of the Ottoman Empire from 1808 until his death in 1839. He was born in the Topkapi Palace, Constantinople,[1] the posthumous son of Sultan Abdulhamid I. His reign is notable mostly for the extensive administrative, military and fiscal reforms he instituted, which culminated into the Decree of Tanzimat (Reorganization) that was carried out by his sons Abdülmecid I and Abdülaziz I. In 1826 he abolished the Janissary corps of 135,000 men and executed thousands of its leaders, thereby removing a major obstacle to army reform.
