The civil war in Poland (1704–1706) was a part of a larger European conflict, the Great Northern War. It focused on the struggle for the Polish throne between King Stanisław I supported by his Warsaw Confederation and Sweden, and the Russian-backed Sandomierz Confederation of Augustus II the Strong. The war ended with Stanisław's victory and the Treaty of Altranstädt in 1706 in which August II renounced his claims to the Polish throne. Stanisław's triumph would be short-lived, however, as by 1709 he would be forced to give up the throne to Augustus II once again.
