The 1622 Janissary Revolt against Sultan Osman II signaled the beginning of the end of the Ottoman Empire.

Explanation:

The seventeenth century, under the sultanates of Mustafa I, Osman II and Murad IV, was a tragic time for the Ottoman Empire. Osman II (1617-1622) was the most cultured sovereign of the entire dynasty. He knew that a political and military reform was necessary, which would overcome the established powers of the jenizaros. These, upon hearing of it, murdered high officials in their own homes, so the sultan had to yield. In spite of everything, he did not escape being murdered at the hands of the janissaries. After the new ascension of Mustafa I they named Murad IV (1623-1640) as the new leader of the Empire. This managed to make some reform in the administration but, when he died, the State was left without leaders and an emptiness of power spread through the Empire for twenty years.
