When did the powerful Ottoman Empire begin to weaken?

The first signs of the weakening of the Ottoman Empire appeared at the turn of the 16th and 17th centuries. After the death of the most famous of its sultans – Suleiman. His successors at the turn of the century proved to be weak rulers. For example, Mehmet III, he ruled in 1595-1603. His reign was a series of setbacks: defeats in the west from the Austrians and the Wallachians (Prince Mihai the Brave), a series of uprisings in the empire itself due to currency devaluation, the Janissary riots in 1595 and 1603.

Finally, the process of weakening the empire can be considered from 1683, after the defeat at Vienna, the Turks then lost Hungary and Azov was given to Russia in 1700.
