The Revolutionary War broke out in the 1770s as American colonists rebelled against British taxation and control over the colonies. Events like the Boston Massacre and Boston Tea Party increased tensions, as the British imposed taxes without representation and closed Boston's port after the tea was destroyed. The British refusal to compromise led the colonies to form the Continental Congress and eventually declare independence, starting the Revolutionary War. Though the British army was better equipped, colonists received aid from the French and used innovative tactics under George Washington to overcome the British forces through guerrilla warfare and ambushes.
