Second Partition of Poland
The 1793 Second Partition of Poland was the second of three partitions (or partial annexations) that ended the existence of the Polish–Lithuanian Commonwealth by 1795. The second partition occurred in the aftermath of the Polish–Russian War of 1792 and the Targowica Confederation of 1792, and was approved by its territorial beneficiaries, the Russian Empire and the Kingdom of Prussia.
