Although the Seven Years' War was a global conflict, it acquired a specific intensity in ita European theater as a result of the competition between Frederick II of Prussia, known as Frederick the Great, and Maria Theresa of Austria. Their rivalry dated from 1740, when upon Maria Theresa's ascension, Frederick had attacked and annexed the prosperous province of Silesia. The 1748 Treaty of Aix-la-Chapelle, which concluded War of the Austrian Succession (1740–1748) between Prussia and Maria Theresa's allies, awarded Silesia to Prussia. Maria Theresa had signed the treaty to gain time to rebuild her military forces and forge new alliances and intended to regain her ascendancy in the Holy Roman Empire and to reacquire Silesia. Similarly, France sought to break the British dominance of the Atlantic trade.
