By the Treaty of St. Petersburg (1762) Russia made peace and restored all conquests; Sweden made peace in the same year. Now fighting alone in the east, the Austrians were soundly defeated at Burkersdorf (July, 1762). The French, too, had suffered severe reverses. In America they had lost Louisburg (1758), Quebec (1759), and some possessions in the West Indies; in India, the British victories at Plassey (1757) and Pondichéry (now Puducherry; 1761) had destroyed French power; on the sea, the French took Port Mahón from the British (1757) but were defeated by Hawke in Quiberon Bay (1759). The entry of Spain into the war under the terms of the Family Compact of 1761 was of little help to France, where the war had never been popular.
After protracted negotiations between the war-weary powers, peace was made (Feb., 1763) among Prussia, Austria, and Saxony at Hubertusburg, and among England, France, and Spain at Paris (see Paris, Treaty of, 1763). The treaty of Hubertusburg, though it restored the prewar status quo, marked the ascendancy of Prussia as a leading European power. Through the Treaty of Paris, Great Britain emerged as the world's chief colonial empire, which was its primary goal in the war, and France lost most of its overseas possessions. For Russia the Seven Years War was the first great venture into purely European affairs.
