Wikipedia Overview

The Khmelnytsky Uprising, also known as the Cossack–Polish War, Khmelnytsky insurrection, Cossack Revolution, or, in Ukraine, as the National Liberation War, was a successful Cossack rebellion with elements of religious war that took place between 1648 and 1657 in the eastern territories of the Polish–Lithuanian Commonwealth. Originating in Dnieper Ukraine, the uprising resulted in a Cossack victory and led to the creation of the Cossack Hetmanate. Under the command of Cossack Hetman Bohdan Khmelnytsky, the Zaporozhian Cossacks, supported by the rebelling Ruthenian peasantry and initially allied with the Crimean Khanate, fought against the Commonwealth's forces. The war was accompanied by mass atrocities committed by Cossacks against prisoners of war and the civilian population, especially Poles, Jews, Roman Catholic and Ruthenian Uniate clergy, as well as reprisals by the Polish szlachta and army, especially Jeremi Wiśniowiecki's troops.
