Upper Saxony
The Second Silesian War () was a war between Prussia and Austria that lasted from 1744 to 1745 and confirmed Prussia's control of the region of Silesia (now in south-western Poland). The war was fought mainly in Silesia, Bohemia, and Upper Saxony and formed one theatre of the wider War of the Austrian Succession. It was the second of three Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria in the mid-18th century, all three of which ended in Prussian control of Silesia.
