 Charles XII of Sweden's victory in the Battle of Fraustadt had forced August the Strong of the Electorate of Saxony to drop out of the Great Northern War and abdicate his claims to the Polish crown in the Treaty of Altranstädt, marking an end to the Civil war in Poland (1704-1706).When he learned of the recently arranged treaty while on his travels with Menshikov, Augustus chose to keep the news from him.His decision was based on the Russians' support through generosity in expenses.
