右岸ウクライナ
Samoylovych's principal ambition was to control the Right-bank Ukraine, where two rival hetmans, Petro Doroshenko and Mykhailo Khanenko, were active. In 1674 he joined his Cossacks with the Russian forces under Prince Grigory Romodanovsky against Doroshenko. After the latter's deposition, Samoylovych let him live in peace on the left bank of the Dnieper.
