Overview
British North America comprised the colonial territories of the British Empire in North America from 1783 onwards. English colonisation of North America began in the 16th century in Newfoundland, then further south at Roanoke and Jamestown, Virginia, and more substantially with the founding of the Thirteen Colonies along the Atlantic coast of North America.
The British Empire's colonial territories in North America were greatly expanded in connection with the Treaty of Paris (1763), which formally concluded the Seven Years' War, referred to by the English colonies in North America as the French and Indian War, and by the French colonies as . With the ultimate acquisition of most of New France, British territory in North America was more than doubled in size, and the exclusion of France also dramatically altered the political landscape of the continent.
The term British America was used to refer to the British Empire's colonial territories in North America prior to the United States Declaration of Independence, most famously in the 1774 address of Thomas Jefferson to the First Continental Congress entitled: A Summary View of the Rights of British America.
The term British North America was initially used following the subsequent 1783 Treaty of Paris, which concluded the American Revolutionary War and confirmed the independence of Great Britain's Thirteen Colonies that formed the United States of America. The terms British America and British North America continued to be used for Britain's remaining territories in North America, but the term British North America came to be used more consistently in connection with the provinces that would eventually form the Dominion of Canada, following the Report on the Affairs of British North America (1839), called the Durham Report.
