タルゴヴィツァ連盟
The long-lasting sejm convened by Stanisław August in 1788 is known as the Great, or Four-Year Sejm. The Sejm's landmark achievement was the passing of the May 3 Constitution, the first in modern Europe singular pronouncement of a supreme law of the state. The reformist but moderate document, accused by detractors of French Revolution sympathies, soon generated strong opposition coming from the Commonwealth's upper nobility conservative circles and Catherine II, determined to prevent a rebirth of a strong Commonwealth. The nobility's Targowica Confederation appealed to the Empress for help and in May 1792 the Russian army entered the territory of the Commonwealth. The defensive war fought by the forces of the Commonwealth ended when the King, convinced of the futility of resistance, capitulated by joining the Targowica Confederation. The Confederation took over the government, but Russia and Prussia in 1793 arranged for and executed the Second Partition of the Commonwealth, which left the country with critically reduced territory, practically incapable of independent existence.
