The land occupied by Canada was inhabited for millennia by various aboriginal people. Beginning in the late 15th century, British and French expeditions explored and later settled the Atlantic coast. France ceded nearly all of its colonies in North America in 1763 after the Seven Years' War. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of additional provinces and territories and a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster in 1931, and culminating in the Canada Act in 1982 which severed the vestiges of legal dependence on the British parliament.
