シュレージエン戦争
The Silesian Wars () were three wars fought in the mid-18th century between Prussia (under King Frederick the Great) and Habsburg Austria (under Archduchess Maria Theresa) for control of the Central European region of Silesia (now in south-western Poland). The First (1740–1742) and Second (1744–1745) Silesian Wars formed parts of the wider War of the Austrian Succession, in which Prussia was a member of a coalition seeking territorial gain at Austria's expense. The Third Silesian War (1756–1763) was a theatre of the global Seven Years' War, in which Austria in turn led a coalition of powers aiming to seize Prussian territory.
