Koliyivschyna
The Koliivshchyna was a major haidamaky rebellion that broke out in Right-bank Ukraine in June 1768, caused by the dissatisfaction of peasants with the treatment of Orthodox Christians by the Bar Confederation and serfdom, as well as by hostility of Cossacks and peasants to the local Polonized Ruthenian nobility and ethnic Poles. The uprising was accompanied by pogroms against both real and imagined supporters of the Bar Confederation, particularly ethnic Poles, Jews, Roman Catholics, and especially Byzantine Catholic priests and laity. This culminated in the massacre of Uman. The number of victims is estimated from 100,000 to 200,000. Many communities of national minorities completely disappeared in the areas devastated by the uprising.
