The shifting borders of a vanished empire
Before the United States existed, a vast, ever-changing patchwork of territories known as British North America stretched across the continent. From the wreckage of shipwrecks in Bermuda to the expansion of the Thirteen Colonies, these borders were shaped by war, treaties, and the strategic ambitions of the British Crown.
The map of British North America was never static. While the 16th-century English colonization began in Newfoundland and moved south toward Jamestown, Virginia, the territory's true expansion came through conflict. The 1763 Treaty of Paris, which ended the Seven Years' War (known in the colonies as the French and Indian War), allowed Britain to more than double its North American holdings by acquiring much of New France.
The term 'British America' was used prior to the American Declaration of Independence, notably in Thomas Jefferson's 1774 address. However, following the 1783 Treaty of Paris—which confirmed the independence of the Thirteen Colonies—the term 'British North America' became more common. This designation eventually became closely associated with the provinces that would form Canada, particularly after the 1839 Durham Report.
The empire's reach included diverse regions: the Atlantic archipelago of Bermuda, the Northwest Territory (which later became several Midwestern U.S. states like Ohio and Michigan), and even parts of Florida and the Bahamas. Bermuda itself played a pivotal role; despite its ties to the rebellious southern colonies, its Royal Navy presence kept it aligned with Britain. By the 19th century, Bermuda served as a vital naval headquarters, even launching expeditions during the War of 1812 that reached as far as the Chesapeake Bay.
The political landscape was finalized through significant legislative milestones, such as the British North America Act of 1867. This act facilitated the creation of the Dominion of Canada, uniting New Brunswick, Nova Scotia, and the Province of Canada into a single dominion under the British Crown.
