外交革命
The seizure of Silesia made Prussia and Austria into lasting and determined enemies, beginning the Austria–Prussia rivalry that would come to dominate German politics over the next century. Saxony, envious of Prussia's ascendancy and threatened by Prussian Silesia's geostrategic position, also turned its foreign policy firmly against Prussia. Frederick's repeated unilateral withdrawal from his alliances in the War of the Austrian Succession deepened the French royal court's distrust of him, and his next perceived "betrayal" (a defensive alliance with Britain under the 1756 Convention of Westminster) accelerated France's eventual realignment toward Austria in the Diplomatic Revolution of the 1750s.
