A great European struggle, which ended twelve years before our Revolution began, had wrought important changes in the political control of North America. The Seven Years' War, identical in time with the French and Indian War in America, was closed in 1763 by numerous treaties to which every great power in Europe was in some sense a party. One of the most striking results of these treaties on this side of the Atlantic was the cession of Florida to Great Britain by Spain in exchange for the release of Cuba, which the English and colonial forces under Lord Albemarle had wrested from Spanish authority the preceding year. England held Florida for twenty years, when among the disasters brought upon her by our Revolution was its retrocession to Spain in 1783,--a result which was accounted by our forefathers a great gain to the new Republic. Still more striking were the losses of France. Fifty years before, by the Treaty of Utrecht, France had surrendered to England the island of Newfoundland, Nova Scotia (then including New Brunswick), and the Hudson-bay Territory. She now gave up Canada and Cape Breton, acknowledged the sovereignty of Great Britain in the original thirteen Colonies as extending to the Mississippi, and, by a separate treaty, surrendered Louisiana on the west side of the Mississippi, with New Orleans on the east side, to Spain. Thus, in 1763, French power disappeared from North American. The last square mile of the most valuable colonial territory ever possessed by a European sovereign was lost under the weak and effeminate rule of Louis XV., a reign not fitted for successful war, but distinguished only, as one of its historians says, for "easy-mannered joyance, and the brilliant charm of fashionable and philosophical society."
