Kozak leader, Petro Doroshenko

In the fall of 1667 Doroshenko, with Ottoman support, defeated the Polish forces in Podolia, and expelled them from the Right-Bank. With the Right-Bank seemingly secured, Doroshenko and his men crossed into Left-bank Ukraine and supported an uprising against Ivan Briukhovetsky. Following Briukhovetsky’s execution the Left-bank regiments proclaimed Doroshenko the hetman of all Ukraine on June 9, 1668. As Doroshenko was reaching his zenith of power after successfully reuniting Ukraine, his numerous enemies united against him.
