Civil war in Poland (1704–1706)

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.

At the onset of the Great Northern War, Augustus the Strong was king of Poland, Grand Duke of Lithuania and Elector of Saxony, having been elected in 1697. In 1699, he allied with the Russian tsar Peter the Great in the Treaty of Preobrazhenskoye and with Frederik IV of Denmark-Norway in the Treaty of Dresden, and joined their war with the Swedish Empire that followed in 1700 Soon, however, their alliance suffered a number of defeats, and led to Charles XII of Sweden invasion of Poland.
