Army of the classical Ottoman Empire

The Ottoman 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's standing army of janissaries that were 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 (Kapıkulu) and peripheral (Eyalet). This army was forced to disband by Sultan Mahmud II on 15 June 1826 in what is known as Auspicious Incident, which followed a century-long reform effort.

The Ottomans were one of the first states to maintain a standing army in Europe since the Roman Empire. The force originated in the 14th century.
