Premise: The First Silesian War was a theatre of the War of the Austrian Succession. The name is used to describe Prussia's war against Austria between 1740 and 1742, fought mainly in Silesia, Moravia and Bohemia (the lands of the Bohemian Crown). It became the first in a series of three Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria.
Hypothesis: Moravia means the lands of the Bohemian Crown.
