The Cossack Revolts were a series of uprisings in Eastern Europe, primarily involving the Cossacks, a group of predominantly East Slavic-speaking people known for their military prowess and semi-nomadic lifestyle. These revolts occurred mainly in the 16th to 18th centuries, driven by grievances against the Polish-Lithuanian Commonwealth and later the Russian Empire, as Cossacks sought greater autonomy and rights. One of the most notable revolts was the Khmelnytsky Uprising in 1648, led by Bohdan Khmelnytsky, which aimed to establish a Cossack state and reduce Polish control. The revolts significantly influenced the political landscape of the region, leading to the eventual incorporation of Cossack territories into the Russian Empire.
