Causes
The 1748 Treaty of Aix-la-Chapelle, ending the War of the Austrian Succession, left all parties dissatisfied with the terms.
A diplomatic revolution in Europe subsequently rearranged old alliances. Great Britain, Prussia, and Hanover became allies. France, Austria, and Russia spearheaded an opposing alliance.
Frederick the Great of Prussia saw an opportunity to expand Prussian territory and influence and invaded Saxony in August 1756. Austria immediately moved to reinforce the Saxons.
The Prussian invasion of Saxony began the Seven Years’ War. The conflict ultimately would be fought on three continents—Europe, North America, and Asia.
