The Bohemian Crown passed to the House of Habsburg in 1526. In 1742, most of Silesia was annexed by Prussia following the First Silesian War. This was confirmed following the Second Silesian War in 1745 and the Third Silesian War in 1763. Following the dissolution of the Holy Roman Empire, Bohemian Silesia remained a part of the Austrian Empire and Austro-Hungarian Empire down to its dissolution in 1918.
