Canada's founding, on 1 July 1867, looks almost deliberately unlike the founding stories of most other new states of its era. There was no war of independence, no revolutionary declaration, no break with the mother country at all: the British North America Act, passed by the British Parliament at Westminster, united the Province of Canada, splitting back into Ontario and Quebec, with Nova Scotia and New Brunswick into a single self-governing federation that remained a Dominion under the British Crown. The impetus was practical rather than ideological: fear of American expansionism in the aftermath of the United States Civil War, the economic logic of a larger internal market and an intercolonial railway, and a wish among colonial politicians to resolve recurring deadlock in the Province of Canada's own legislature. The result was a new constitutional category, Dominion, that let Canada govern its own domestic affairs, taxation, courts, most legislation, while Britain retained control over foreign policy and constitutional amendment, a halfway status between colony and sovereign nation that no earlier settler colony had held. That negotiated, gradualist character shaped everything that followed: further territory was added by purchase and negotiation rather than conquest, from Rupert's Land in 1870 to Newfoundland as late as 1949, and full legal sovereignty arrived not in one dramatic instant but across decades, through the 1931 Statute of Westminster and finally the 1982 patriation of the constitution.
