The Tarnogród Confederation was a confederation of szlachta in Polish–Lithuanian Commonwealth, in the years 1715–1716. It was formed on 26 November 1715 in Tarnogród by nobility angered by illegal taxation, levied for Saxon forces operating in Grand Duchy of Lithuania on behalf of Augustus II the Strong, who wanted to introduce absolute monarchy in the Commonwealth. Its marshal was Stanisław Ledóchowski. The confederates and the royal forces did not fight any decisive battles, but they fought numerous smaller skirmishes; several towns and castles were taken. The ensuing negotiations eventually brought Peter I of Russia and Russian Empire forces into the Commonwealth "for peacekeeping and mediation". This event marked the beginning of lasting Russian Empire influence on Commonwealth internal affairs, starting with the Silent Sejm of 1717.
