Khmelnytsky Uprising

Timeline

1. 1648Chyhyryn · UkraineKhmelnytsky, embittered by the seizure of his estate by nobles and the killing of his son, raised the banner against Poland at Chyhyryn with Zaporozhian Cossack support. News of the uprising spread rapidly, and peasants, urban lower classes, and Cossacks joined in, forming a widespread challenge to Polish local rule.
2. 1648Korsun · UkrainePolish royal army general Stefan Potocki led troops south to suppress the uprising, but was ambushed at Korsun by a joint Cossack and Crimean Tatar force and his army was annihilated. This battle greatly boosted the uprising's momentum, caused the collapse of Poland's eastern defenses, and led large areas of Ukraine to slip from effective Commonwealth control.
3. 1648–1649Ukraine · UkraineFollowing Korsun, the Cossack allied forces won further victories over Polish armies at battles such as Bila Tserkva and Pyliavtsi, and Kyiv and other places fell successively into rebel hands. The Polish–Lithuanian Commonwealth fell into a severe military and financial crisis, forced to negotiate with the Cossacks, paving the way for the Siege of Zbarazh and the Treaty of Zboriv.
