a military alliance formed by the Polish gentry and directed against the Polish king Stanisław Poniatowski and tsarist Russia.
The Confederation of Bar was established on Feb. 29, 1768, in the city of Bar (Podolia). The confederation advocated the preservation of the privileges of the Catholic Church and the liberties enjoyed by the gentry, and it opposed reforms in the governmental structure of Poland and equal rights for non-Catholic Christians. Certain patriotic gentry circles who defended the independence of the country also participated in the Confederation of Bar. The struggle between the confederates and the troops of the king and tsarist Russia continued until 1772. The suppression of the Confederation of Bar laid the foundation for the First Partition of Poland.
