1793

By the 1790s the First Polish Republic had deteriorated into such a helpless condition that it was successfully forced into an alliance with its enemy, Prussia. The alliance was cemented with the Polish–Prussian Pact of 1790.pg 128 – pg 128 – ''The result was the March 1790 Polish–Prussian alliance ... Warsaw's viewpoint the alliance made sense, but the sejm's refusal to pay Prussia's price for it ... made it of problematic value.'' The conditions of the Pact were such that the succeeding and final two partitions of Poland were inevitable. The May Constitution of 1791 enfranchised the bourgeoisie, established the separation of the three branches of government, and eliminated the abuses of Repnin Sejm. Those reforms prompted aggressive actions on the part of Poland's neighbours, wary of a potential renaissance of the Commonwealth. In the second partition, Russia and Prussia took so much territory that only one-third of the 1772 population remained in Poland.pg 101–103 – - ''the Prussians and the Russians signed a second treaty of Partition in St Petersburg on 23 January 1793. Catherine would take a slab of land ... William would acquire a triangle of territory between Silesia and East Prussia.''


1795

Kosciuszko's insurgent armies, who fought to regain Polish territory, won some initial successes but they eventually fell before the 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.

Congress Poland

Congress Poland was created out of the Duchy of Warsaw at the Congress of Vienna in 1815, when European states reorganized Europe following the Napoleonic wars.


Grand Duchy of Posen

The Grand Duchy of Posen was a region in the Kingdom of Prussia in the Polish lands commonly known as "Greater Poland" between the years 1815–1848. According to the Congress of Vienna, it was to have autonomy. In practice, it was subordinated to Prussia and the proclaimed rights for Poles were not respected. The name was unofficially used afterwards for denoting the territory, especially by Poles, and today is used by modern historians to describe different political entities until 1918. Its capital was Posen (Polish:
Poznań Poznań () is a city on the River Warta in west-central Poland, within the Greater Poland region. The city is an important cultural and business centre, and one of Poland's most populous regions with many regional customs such as Saint Joh ...

1848

After the defeat of Congress Poland, many Prussian liberals sympathised with the demand for the restoration of the Polish state. In the spring of 1848 the new liberal Prussian government allowed some autonomy to the Grand Duchy of Posen in the hope of contributing to the cause of a new Polish homeland.pg 107 –

In the spring of 1848 the new liberal Prussian government allowed some autonomy to Posen in the hope of contributing to the cause of restoration.''
Due to a number of factors, including the outrage of the German-speaking minority in Posen, the Prussian government reversed course. By April 1848, the Prussian army had already suppressed the Polish militias and National Committees that emerged in March. By the end of the year the Duchy had lost the last vestiges of its formal autonomy, and was downgraded to a Province of the Prussian kingdom.pg 178 -

Soon after the Battle of Warsaw the Bolsheviks sued for peace.

On the October 5, the Soviets offered amendments to the Polish offer, which Poland accepted.
