Following the
First Partition of Poland in 1772, in an attempt to strengthen the significantly weakened Commonwealth, King
Stanisław August Poniatowski put into effect a series of reforms to enhance Poland's military, political system, economy, and society. These reforms reached their climax with the enactment of the May Constitution in 1791, which established a constitutional monarchy with separation into three branches of government, strengthened the bourgeoisie and abolished many of the
nobility's privileges as well as many of the old laws of serfdom. In addition, to strengthen Poland's international standings, King Stanislaus signed the
Polish-Prussian Pact of 1790. Angered by what was seen as dangerous,
Jacobin-style reforms, Russia invaded Poland in 1792, beginning the
War in Defense of the Constitution. Abandoned by her Prussian allies and betrayed by Polish nobles who desired to restore the privileges they had lost under the May Constitution, Poland was forced to sign the
Second Partition in 1793, which ceded Dobrzyn, Kujavia, and a large portion of Greater Poland to Prussia and all of Poland's eastern provinces from
Moldavia to
Livonia to Russia, reducing Poland to one-third of her original size before the First Partition. Outraged with the further humiliation of Poland by its neighbors and the betrayal by the Polish nobility, and emboldened by the
French Revolution unfolding in France, the Polish masses quickly turned against the occupying forces of Prussia and Russia. Following a series of nationwide riots, on 24 March 1794, Polish patriot
Tadeusz Kościuszko took command of the
Polish armed forces and declared a nationwide uprising against Poland's foreign occupiers, marking the beginning of the
Kościuszko Uprising.
Catherine II and
Frederick William II were quick to respond and, despite initial successes by Kosciuszko's forces, the uprising was crushed by November 1794. According to legend, when Kosciuszko fell off of his horse at the
Battle of Maciejowice, shortly before he was captured, he said "Finis Poloniae", meaning in Latin "[This is] the end of Poland." ==Terms==
