Selim III (Ottoman Turkish: slym thlth Selim-i salis) (24 December 1761 - 28 July 1808) was the reform-minded Sultan of the Ottoman Empire from 1789 to 1807. The Janissaries eventually deposed and imprisoned him, and placed his cousin Mustafa on the throne as Mustafa IV. Selim was subsequently killed by a group of assassins.
Plans of reforms
The talents and energy with which Selim III was endowed had endeared him to the people, and great hopes were founded on his accession. He had associated much with foreigners, and was thoroughly persuaded of the necessity of reforming his state.  However, Austria and Russia gave him no time for anything but defense, and it was not until the Peace of Iasi (1792) that a breathing space was allowed him in Europe, while Napoleon's invasion of Egypt and Syria soon called for Turkey's strongest efforts.  Selim III profited by the respite to abolish the military tenure of fiefs; he introduced salutary reforms into the administration, especially in the fiscal department, sought by well-considered plans to extend the spread of education, and engaged foreign officers as instructors, by whom a small corps of new troops called nizam-i-jedid were collected and drilled in 1797. This unit was composed of Turkish peasant youths from Anatolia and supplied with modern weaponry.  These troops were able to hold their own against rebellious Janissaries in the Balkan provinces such as the Sanjak of Smederevo against its appointed Vizier Hadzi Mustafa Pasha, where disaffected governors made no scruple of attempting to make use of them against the reforming sultan.  Emboldened by this success, Selim III issued an order that in future picked men should be taken annually from the Janissaries to serve in the nizam-i-jedid. Selim III was unable to integrate the nizam-i jedid with the rest of the army which overall limited its role in the defense of the state.
