Throughout the 1750s and 1760s, ordinary colonists challenged the authority of economic and political elites to impose their will on local communities and individual residents. Before and during the French and Indian War, most of these challenges involved conflicts among colonists themselves. Yet in the decade following the war, from 1764 to 1774, common grievances against Britain united colonists on the frontier and along the eastern seaboard, allowing them to launch effective protests against the British government. British policies, like the Proclamation Line of 1763, inspired widespread dissent as poor farmers, large landowners, and speculators sought to expand westward. A second policy, impressment, by which the Royal Navy forced young colonial men into military service, also aroused anger across regions and classes. At the same time, the Great Awakening, for all the upheaval it had engendered, provided colonists with shared ideas about moral principles and new techniques for mass communication. Finally, Britain’s efforts to repay its war debts by taxing colonists and its plan to continue quartering troops in North America led colonists to forge intercolonial protest movements.
