Stanisław II August, known also by his regnal Latin name Stanislaus II Augustus, and as Stanisław August Poniatowski, was King of Poland and Grand Duke of Lithuania from 1764 to 1795, and the last monarch of the Polish–Lithuanian Commonwealth.

The Targowica Confederation was a confederation established by Polish and Lithuanian magnates on 27 April 1792, in Saint Petersburg, with the backing of the Russian Empress Catherine II. The confederation opposed the Constitution of 3 May 1791 and fought in the Polish–Russian War of 1792, which led to the Second and Third Partitions of Poland.
