The
Partitions of Poland or
Partitions of the Polish Lithuanian Commonwealth[1][2][3] took place in the second half of the
18th century and ended the existence of the
Polish–Lithuanian Commonwealth. The
partitions were carried out by
Prussia,
Russia and
Habsburg Austria dividing up the Commonwealth lands among themselves. Three partitions took place
The less often used term "Fourth Partition of Poland" may refer to any subsequent division of Polish lands, specifically
During the reign of Wladyslaw IV (1632-48), the liberum veto had evolved. This policy of parliamentary procedure was based on the assumption of the political equality of every "gentleman", with the corollary that unanimous consent was required for all measures. A single MP's belief that a measure was injurious to his own constituency (usually simply his own estate), even after the act had already been approved, became sufficient to strike the act. It became increasingly difficult to get action taken. The liberum veto also provided openings for foreign diplomats to get their ways, through bribing nobles to exercise it. Thus one could characterise Poland-Lithuania in its final period (mid-18th century), prior to the partitions as already not a completely sovereign state it could be seen almost as a vassal,[5] or in modern terms, a Russian satellite state, with Russian tsars effectively choosing Polish kings. This applies particularly to the last Commonwealth King Stanislaw August Poniatowski, who for some time had been a lover of Russian Empress Catherine the Great.
In 1730 the neighbours of the Polish-Lithuanian Commonwealth (Rzeczpospolita), namely Prussia, Austria and Russia, signed a secret agreement in order to maintain the status quo 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 Löwenwolde'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, while Prussia was demanding a slice of the northwest in order to unite its Western and Eastern portions, although this would only leave the Commonwealth with a Baltic coast in Latvia and Lithuania. The Commonwealth could never be liquidated unless its longtime ally, Austria, allowed it,[citation needed] and first Catherine had to use diplomacy to win Austria to her side.
