Seven Years%27 War:

The British government was close to bankruptcy, and Britain now faced the delicate task of pacifying its new French-Canadian subjects as well as the many American Indian tribes who had supported France. George III's Proclamation of 1763, which forbade white settlement beyond the crest of the Appalachians, was intended to appease the latter but led to considerable outrage in the Thirteen Colonies, whose inhabitants were eager to acquire native lands. The Quebec Act of 1774, similarly intended to win over the loyalty of French Canadians, also spurred resentment among American colonists. The act protected Catholic religion and French language, which enraged the Americans, but the Québécois remained loyal and did not rebel.
