Q: What was the American Revolution?

The American Revolution —also called the U.S. War of Independence—was the insurrection fought between 1775 and 1783 through which 13 of Great Britain ’s North American colonies threw off British rule to establish the sovereign United States of America, founded with the Declaration of Independence in 1776. British attempts to assert greater control over colonial affairs after a long period of salutary neglect , including the imposition of unpopular taxes, had contributed to growing estrangement between the crown and a large and influential segment of colonists who ultimately saw armed rebellion as their only recourse.

Q: How did the American Revolution begin?

On the ground, fighting in the American Revolution began with the skirmishes between British regulars and American provincials on April 19, 1775 , first at Lexington , where a British force of 700 faced 77 local minutemen , and then at Concord , where an American counterforce of 320 to 400 sent the British scurrying. The British had come to Concord to seize the military stores of the colonists, who had been forewarned of the raid through efficient lines of communication—including the ride of Paul Revere , which is celebrated with poetic license in Longfellow ’s “Paul Revere’s Ride” (1861).

Q: What were the major causes of the American Revolution?

The American Revolution was principally caused by colonial opposition to British attempts to impose greater control over the colonies and to make them repay the crown for its defense of them during the French and Indian War (1754–63). Britain did this primarily by imposing a series of deeply unpopular laws and taxes, including the Sugar Act (1764), the Stamp Act (1765), and the so-called Intolerable Acts (1774).

Q: Which countries fought on the side of the colonies during the American Revolution?

Until early in 1778, the American Revolution was a civil war within the British Empire , but it became an international war as France (in 1778) and Spain (in 1779) joined the colonies against Britain. The Netherlands , which was engaged in its own war with Britain, provided financial support for the Americans as well as official recognition of their independence. The French navy in particular played a key role in bringing about the British surrender at Yorktown , which effectively ended the war.

Q: How was the American Revolution a civil war?

In the early stages of the rebellion by the American colonists, most of them still saw themselves as English subjects who were being denied their rights as such. “Taxation without representation is tyranny,” James Otis reportedly said in protest of the lack of colonial representation in Parliament . What made the American Revolution look most like a civil war , though, was the reality that about one-third of the colonists, known as loyalists (or Tories), continued to support and fought on the side of the crown.

The American Revolution was an insurrection carried out by 13 of Great Britain’s North American colonies that began in 1775 and ended with a peace treaty in 1783. The colonies won political independence and went on to form the United States of America. The war followed more than a decade of growing estrangement between the British crown and a large and influential segment of its North American colonies that was caused by British attempts to assert greater control over colonial affairs after having long adhered to a policy of salutary neglect.
