Context: Britain gained control of French Canada and Acadia, colonies containing approximately 80,000 primarily French-speaking Roman Catholic residents. The deportation of Acadians beginning in 1755 made land available to immigrants from Europe and migrants from the colonies to the south. The British resettled many Acadians throughout its North American provinces, but many went to France, and some went to New Orleans, which they had expected to remain French. Some were sent to colonize places as diverse as French Guiana and the Falkland Islands, but these efforts were unsuccessful. Others migrated to places such as Saint-Domingue or fled to New Orleans after the Haitian Revolution. The Louisiana population contributed to the founding of the modern Cajun population. Following the treaty, King George III issued the Royal Proclamation of 1763 on October 7, 1763 which outlined the division and administration of the newly conquered territory, and it continues to govern relations to some extent between the government of modern Canada and the First Nations. Included in its provisions was the reservation of lands west of the Appalachian Mountains to its Indian population, a demarcation that was only a temporary impediment to a rising tide of westward-bound settlers. The proclamation also contained provisions that prevented civic participation by the Roman Catholic Canadians. The Quebec Act addressed this and other issues in 1774, raising concerns in the largely Protestant Thirteen Colonies over the advance of "popery." The Act maintained French Civil law, including the seigneurial system, a medieval code removed from France within a generation by the French Revolution.
