Khmelnytsky Uprising
The Khmelnytsky Uprising (; in Ukraine known as Khmelʹnychchyna or ; ; Belarusian: Паўстанне Багдана Хмяльніцкага; ), also known as the Cossack-Polish War, the Chmielnicki Uprising, the Khmelnytsky massacre or the Khmelnytsky insurrection, was a Cossack rebellion that took place between 1648 and 1657 in the eastern territories of the Polish–Lithuanian Commonwealth, which led to the creation of a Cossack Hetmanate in Ukraine. Under the command of Hetman Bohdan Khmelnytsky, the Zaporozhian Cossacks, allied with the Crimean Tatars and local Ukrainian peasantry, fought against Polish domination and against the Commonwealth forces. The insurgency was accompanied by mass atrocities committed by Cossacks against the civilian population, especially against the Roman Catholic clergy and the Jews.
