Based on the terms of the treaty, Maria Theresa ceded most of the Silesian duchies to Prussia except for the Duchy of Teschen, the districts of Troppau and Krnov south of the Opava river as well as the southern part of the Duchy of Nysa, that were all to become the province of Austrian Silesia. Furthermore, Frederick annexed the Bohemian County of Kladsko.


Despite the popular name of the treaty, it was actually signed in Berlin.[1] This treaty, along with the Treaty of Berlin signed on 28 July 1742, officially ended the First Silesian War. Except for the partition of Cieszyn Silesia and the incorporation of the Hlučín Region in 1920, the 1742 demarcation line today still determines the border of the Czech Republic with Poland.
