Reformers and patriots were soon preparing for a national insurrection. Tadeusz Kościuszko, chosen as its leader, on March 24, 1794 in Cracow (Kraków) declared a national uprising. Kościuszko emancipated and enrolled in his army many peasants, but the hard-fought insurrection ended in suppression by the forces of Russia and Prussia. The third and final partition of the Commonwealth was undertaken again by all three partitioning powers, and in 1795 the Polish–Lithuanian Commonwealth ceased to exist.
