Osman II blamed the stalemate of war on the lack of zeal and the "degeneracy" of the Janissaries. His efforts at modernizing the Ottoman army were not well received by the Janissaries and the conservative "learned" class. A revolt led by Janissaries and the students of the madrases erupted on 18 May 1622 and Osman II was deposed; two days later he was killed by the rebels who deposed him.
