Mehmed IV
Vouched for by Charles Marie François Olier, marquis de Nointel, Yuriy Khmelnytsky was freed from Ottoman captivity and, along with Pasha Ibragim, was sent to Ukraine to fight the Moscow forces of Samoilovych and Romadanovsky. In 1681, Mehmed IV appointed George Ducas hetman of Ukraine, replacing Khmelnytsky.
