How did Maria Theresa help end the War of the Bavarian Succession?

Maria Theresa played a decisive role in ending the War of the Bavarian Succession by intervening directly against the wishes of her son and co-regent, Joseph II, and her chancellor, Wenzel Anton von Kaunitz.12

Although she had reluctantly consented to the initial occupation of Bavaria, she became a champion of peace as the conflict progressed. She bypassed her son’s aggressive policies and initiated direct peace negotiations with her old adversary, Frederick II of Prussia.12

These efforts led to the Treaty of Teschen, signed on May 13, 1779, with the assistance of France and Russia as intermediaries. The treaty successfully concluded the war by canceling the proposed exchange of the Austrian Netherlands for Bavaria, resulting in only minor territorial adjustments, specifically the addition of the Inn district to Upper Austria.12
