The term Manifest Destiny was first used in 1845 by New York City journalist John Louis O’Sullivan. He used the term in the context of America’s annexation of the Republic of Texas. Manifest Destiny represented the idea that it was America’s right — its destiny, in fact — to expand across all of North America. Politicians and citizens in the United States called for the US to expand by claiming control of British territory. This included the Province of Canada (formerly Upper Canada and Lower Canada), New Brunswick and Nova Scotia.
The War Measures Act was a federal law adopted by Parliament on 22 August 1914, after the outbreak of the First World War. It gave broad powers to the Canadian government to maintain security and order during war or insurrection. It was used, controversially, to suspend the civil liberties of people in Canada who were considered “enemy aliens” during both world wars, leading to mass arrest and detention without charge or trial. The Act was also invoked during the 1970 October Crisis in Quebec. It has since been replaced by the more limited Emergencies Act.
The Royal Proclamation of 1763 was issued by King George III on 7 October 1763. It established the basis for governing the North American territories surrendered by France to Britain in the Treaty of Paris, 1763, following the Seven Years’ War. It introduced policies meant to assimilate the French population to British rule. These policies ultimately failed and were replaced by the Quebec Act of 1774 (see alsoThe Conquest of New France). The Royal Proclamation also set the constitutional structure for the negotiation of treaties with the Indigenous inhabitants of large sections of Canada. It is referenced in section 25 of the Constitution Act, 1982. As such, it has been labelled an “Indian Magna Carta” or an “Indian Bill of Rights.” The Proclamation also contributed to the outbreak of the American Revolutionary War in 1775. The Proclamation legally defined the North American interior west of the Appalachian Mountains as a vast Indigenous reserve. This angered people in the Thirteen Colonies who desired western expansion.
