After the First Silesian War, by the terms of the Treaty of Breslau in 1742, the Opava in the Duchy of Troppau became the border between Austrian and Prussian Silesia (the later Province of Silesia). After World War I the demarcation was confirmed by the 1919 Treaty of Saint-Germain-en-Laye as the border between Czechoslovakia (Czech Silesia) and the Second Polish Republic.
