Between 1750 and 1763, three significant events transformed colonial life. First, Britain went to war against the French in America, sparking a worldwide conflict: the Great War for Empire. Second, a surge in trade boosted colonial consumption but caused Americans to become deeply indebted to British creditors. Third, westward migration sparked warfare with Indian peoples, violent disputes between settlers and land speculators, and backcountry rebellions against eastern-controlled governments.
