The Kościuszko Uprising, also known as the Polish Uprising of 1794 and the Second Polish War, was an uprising against the Russian Empire and the Kingdom of Prussia led by Tadeusz Kościuszko in the Polish–Lithuanian Commonwealth and the Prussian partition in 1794. It was a failed attempt to liberate the Polish–Lithuanian Commonwealth from Russian influence after the Second Partition of Poland (1793) and the creation of the Targowica Confederation. The uprising ended with the Russian occupation of Warsaw.
