Ottoman Classical Army was the military structure established by Mehmed II, during his reorganization of the state and the military. This was the major reorganization following Orhan I's standing army paid by salary rather than booty or fiefs. This army was the force during the rise of the Ottoman Empire. The organization was twofold, central (Kapu Kulu) and peripheral (Eyalet). This army was forced to disbandment by Sultan Mahmud II on 15 June 1826 by what is known as Auspicious Incident following a century long reform efforts.
