Kalisz During the reign of
Władysław IV (1632–1648), the was developed, a policy of parliamentary procedure based on the assumption of the political equality of every "
gentleman/Polish nobleman", with the corollary that unanimous consent was needed for all measures. This applies particularly to the last Commonwealth King
Stanisław August Poniatowski, who for some time had been a lover of Russian Empress
Catherine the Great. In 1730, the neighbors of the Polish–Lithuanian Commonwealth (), namely Prussia, Austria and Russia, signed a secret agreement to maintain the : specifically, to ensure that the Commonwealth laws would not change. Their alliance later became known in Poland as the "
Alliance of the Three Black Eagles" (or '
s Treaty), because all three states used a black eagle as a state symbol (in contrast to the
white eagle, a symbol of Poland). The Commonwealth had been forced to rely on Russia for protection against the rising
Kingdom of Prussia, which demanded a slice of the northwest in order to unite its Western and Eastern portions; this would leave the Commonwealth with a
Baltic coast only in
Latvia and
Lithuania. and others). This new constitution undid the reforms made in 1764 under
Stanisław II. The and all the old abuses of the last one and a half centuries were guaranteed as unalterable parts of this new constitution (in the so-called
Cardinal Laws). Repnin also demanded the Russian protection of the rights of peasants in private estates of Polish and Lithuanian noblemen, religious freedom for the Protestant and
Orthodox Christians and the political freedoms for Protestants, Orthodox Christians and
Eastern Catholics (Uniates), including their right to occupy all state positions, including a royal one. The next king could be a member of the Russian ruling dynasty now. The Sejm approved this. Resulting reaction among some of Poland's Roman Catholics, as well as the deep resentment of Russian intervention in the Commonwealth's domestic affairs including the exile to Russia of the top Roman Catholic bishops, the members of the Polish Senate, led to the War of the
Confederation of Bar of 1768–1772, formed in
Bar, where the Poles tried to expel Russian forces from Commonwealth territory. As Russia moved into the Crimea and the Danubian Principalities (which the Habsburg monarchy long coveted), King Frederick II of Prussia and Maria Theresa were worried that the defeat of the Ottoman Empire would severely upset the balance of power in Eastern Europe. Frederick II began to construct the partition to rebalance the power in Eastern Europe.
First Partition '', oil on canvas by Jan Matejko, 1866, ,
Royal Castle in Warsaw In February 1772, the agreement of partition was signed in
Vienna. Early in August, Russian, Prussian and Austrian troops occupied the provinces agreed upon among themselves. However, fighting continued as Bar confederation troops and French volunteers refused to lay down their arms (most notably, in
Tyniec,
Częstochowa and
Kraków). On 5 August 1772, the occupation manifesto was issued, to the dismay of the weak and exhausted Polish state; the partition treaty was ratified by its signatories on 22 September 1772. Frederick II of Prussia was elated with his success; Prussia took most of
Royal Prussia (except
Gdańsk) that stood between its possessions in
Prussia and the
Margraviate of Brandenburg, as well as Ermland (
Warmia), northern areas of
Greater Poland along the
Noteć River (the
Netze District), and parts of
Kuyavia (but not the city of
Toruń). After having occupied their respective territories, the three partitioning powers demanded that King
Stanisław and the
Sejm approve their action. When no help was forthcoming and the armies of the combined nations occupied Warsaw to compel by force of arms the calling of the assembly, the only alternative was passive submission to their will. The so-called
Partition Sejm, with Russian military forces threatening the opposition, on 18 September 1773, signed the treaty of cession, renouncing all claims of the Commonwealth to the occupied territories. In 1772,
Jean-Jacques Rousseau was invited to present recommendations for a new constitution for the
Polish–Lithuanian Commonwealth, resulting in the
Considerations on the Government of Poland (1782), which was to be his last major political work.
Second Partition By 1790, the Commonwealth had been weakened to such a degree that it was forced into an unnatural and terminal alliance with its enemy, Prussia. The
Polish–Prussian Pact of 1790 was signed. The conditions of the Pact contributed to the subsequent final two partitions of Poland–Lithuania. The
Constitution of 3 May 1791 enfranchised the
bourgeoisie, established the separation of the three branches of government, and eliminated the abuses of the
Repnin Sejm. Those reforms prompted aggressive actions on the part of its neighbours, wary of the potential renaissance of the Commonwealth. Arguing that Poland had fallen prey to the radical
Jacobinism then at high tide in
France, Russian forces invaded the Commonwealth in 1792. In the
War in Defense of the Constitution, pro-Russian conservative Polish
magnates, the
Confederation of Targowica, fought against Polish forces supporting the constitution, believing that Russians would help them restore the
Golden Liberty. Abandoned by their Prussian allies, Polish pro-constitution forces, faced with Targowica units and the regular Russian army, were defeated. Prussia signed a treaty with Russia, agreeing that Polish reforms would be revoked, and both countries would receive chunks of the Commonwealth territory. In 1793, deputies to the
Grodno Sejm, the last Sejm of the Commonwealth, in the presence of the Russian forces, agreed to Russian territorial demands. In the Second Partition, Russia and Prussia helped themselves to enough land so that only one-third of the 1772 population remained in Poland. Prussia named its newly gained province
South Prussia, with
Poznań (and later Warsaw) as the capital of the new province. Targowica confederates, who did not expect another partition, and the king,
Stanisław August Poniatowski, who joined them near the end, both lost much prestige and support. The reformers, on the other hand, were attracting increasing support, and in 1794 the
Kościuszko Uprising began.
Third Partition Kosciuszko's ragtag insurgent armies won some initial successes, but they eventually fell before the superior forces of the Russian Empire. The partitioning powers, seeing the increasing unrest in the remaining Commonwealth, decided to solve the problem by erasing any independent Polish state from the map. On 24 October 1795, their representatives signed a treaty, dividing the remaining territories of the Commonwealth between their three countries. One of Russia's chief foreign policy authors,
Alexander Bezborodko, advised
Catherine II on the Second and Third Partitions of Poland. The Russian part included and 1.2 million people with
Vilnius, the Prussian part (new provinces of
New East Prussia and
New Silesia) and 1 million people with Warsaw, and the Austrian with 1.2 million and
Lublin and Kraków. == Aftermath ==
