The Revolutionary War (one of my favorites to study) began in 1775 and ended in 1783. The Revolutionary War included English forces, American Colonial forces, Hessians (defeated Christmas Day when George Washington crossed the Delaware!) and the French (most notably Lafayette, who was thanked and repaid on the beaches of Normandy in the nineteen-forties).
In 1766, the British imposed the Townshend Act, which taxed a great deal of British imports. The Colonists, however, were not represented in England, hence "no taxation without representation." In 1773, frustrated Colonists dressed up as Mohawks and dumped boxes upon boxes of tea (342 chests) into the Boston Harbor. It was repeated in spirit across the country earlier this year.
