As a result of the mid–17th century Khmelnytsky Uprising, the Zaporozhian Cossacks briefly established an independent state, which later became the autonomous Cossack Hetmanate (1649–1764). It was placed under the suzerainty of the Russian Tsar from 1667 but was ruled by local hetmans for a century. The principal political problem of the hetmans who followed the Pereyeslav Agreement was defending the autonomy of the Hetmanate from Russian/Muscovite centralism. The hetmans Ivan Vyhovsky, Petro Doroshenko and Ivan Mazepa attempted to resolve this by separating Ukraine from Russia.
