The First Partition of Poland was decided on August 5, 1772. Two decades later, Russian and Prussian troops entered the Commonwealth again and the Second Partition was signed on January 23, 1793. Austria did not participate in the Second Partition. The Third Partition of Poland took place on October 24, 1795, in reaction to the unsuccessful Polish Kościuszko Uprising the previous year. With this partition, the Commonwealth ceased to exist.[1]
