Three treaties erased Poland-Lithuania for 123 years
Between 1772 and 1795, Habsburg Austria, Prussia, and Russia carved up the Polish–Lithuanian Commonwealth in three staged annexations. The last stroke, after a failed uprising, abolished the state entirely. Poles and Lithuanians would wait 123 years before full sovereignty returned.
The First Partition was settled on 5 August 1772 after the Bar Confederation's defeat by Russia; Vienna's February deal put armies into agreed provinces, and the occupation manifesto followed that August. Prussia seized most of Royal Prussia (minus Gdańsk), Warmia, the Netze District, and parts of Kuyavia—linking Brandenburg to East Prussia. Austria took rich salt country around Bochnia and Wieliczka plus large slices of Lesser Poland and Galicia (without Kraków). Russia gained land east of roughly the Dvina–Dnieper line, including Latgale and Belarusian cities such as Vitebsk. The commonwealth lost about 30 percent of its territory and half its people—some four million—while Prussia suddenly controlled roughly 80 percent of its foreign trade and piled on customs duties.
Internal paralysis helped outsiders. The liberum veto, matured under Władysław IV (1632–1648), let one noble kill legislation and invited foreign bribes. In 1730 Prussia, Austria, and Russia secretly pledged to freeze commonwealth law—Poles later nicknamed the pact for the black eagles on all three crowns. Catherine the Great's envoy Nicholas Repnin dictated the 1767 Sejm, exiled opponents, undid 1764 reforms, and locked the old abuses into "Cardinal Laws." Frederick II of Prussia even flooded Poland with counterfeit coin after the commonwealth's Seven Years' War neutrality favored Russia's side.
Reform briefly flared. The Constitution of 3 May 1791 enfranchised burghers, separated powers, and attacked Repnin-era abuses. Russia invaded in 1792 under a Jacobin scare; the Targowica Confederation of conservative magnates fought the constitution's defenders. Prussia abandoned its 1790 Polish ally, joined Russia, and the Grodno Sejm of 23 January 1793 rubber-stamped the Second Partition—leaving only about a third of the 1772 population inside the rump state. After the crushed Kościuszko Uprising, the Third Partition of 24 October 1795 extinguished the commonwealth. Later writers stretch a "Fourth Partition" to 1815, 1832–1846, or even 1939, or to the diaspora that helped restore Poland after 1918.
