The French and Indian War is the common American name for the war between Great Britain and France in North America from 1754 to 1763. In 1756, the war erupted into the world-wide conflict known as the Seven Years' War and thus came to be regarded as the North American theater of that war...

 (1754–1763) was a watershed event in the political development of the colonies. The influence of the main rivals of the British Crown in the colonies and Canada, the French and North American Indians, was significantly reduced. Moreover, the war effort resulted in greater political integration of the colonies, as symbolized by Benjamin Franklin's call for the colonies to "Join or Die".

Following Britain's acquisition of French territory in North America, King George III issued the Royal Proclamation of 1763

The British government felt that the colonies were the primary beneficiaries of this military presence, and should pay at least a portion of the expense. The colonists did not share this view. Rather, with the French and Indian threat diminished, the primary outside influence remained that of Britain.

 (1732–1799) proved an excellent organizer and administrator, who worked successfully with Congress and the state governors, selecting and mentoring his senior officers, supporting and training his troops, and maintaining an idealistic Republican Army. His biggest challenge was logistics, since neither Congress nor the states had the funding to provide adequately for the equipment, munitions, clothing, paychecks, or even the food supply of the soldiers. As a battlefield tactician Washington was often outmaneuvered by his British counterparts. As a strategist, however, he had a better idea of how to win the war than they did. The British sent four invasion armies. Washington's strategy forced the first army out of Boston in 1776, and was responsible for the surrender of the second and third armies at Saratoga (1777) and Yorktown (1781). He limited the British control to New York and a few places while keeping Patriot control of the great majority of the population. The Loyalists, whom the British counted upon too heavily, comprised about 20% of the population but never were well organized. As the war ended, Washington watched proudly as the final British army quietly sailed out of New York City in November 1783, taking the Loyalist leadership with them. Washington astonished the world when, instead of seizing power for himself, he retired quietly to his farm in Virginia. Political scientist Seymour Martin Lipset

The main contributions of the U.S. to the Allied war effort comprised money, industrial output, food, petroleum, technological innovation, and (especially 1944-45), soldiers. Much of the focus in Washington was maximizing the economic output of the nation. The overall result was a dramatic increase in GDP, the export of vast quantities of supplies to the Allies and to American forces overseas, the end of unemployment, and a rise in civilian consumption even as 40% of the GDP went to the war effort. This was achieved by tens of millions of workers moving from low-productivity occupations to high efficiency jobs, improvements in productivity through better technology and management, and the move into the active labor force of students, retired people, housewives, and the unemployed, and an increase in hours worked. It was exhausting; leisure activities declined sharply. People tolerated the extra work because of patriotism, the pay, and the confidence it was only "for the duration" and life would return to normal as soon as the war was won. Most durable goods became unavailable, and meat, clothing, and gasoline were tightly rationed. In industrial areas housing was in short supply as people doubled up and lived in cramped quarters. Prices and wages were controlled, and Americans saved a high portion of their incomes, which led to renewed growth after the war instead of a return to depression.
