American Revolutionary War [SEP] Introduction
The American Revolutionary War (1775-1783), also known as the American War of Independence, was initiated by the thirteen original colonies in Congress against Great Britain over their objection to Parliament's direct taxation and its lack of colonial representation. From their founding in the 1600s, the colonies were largely left to govern themselves. When France left North America in 1763, the British Empire expanded, and the elected part of the colonial legislatures challenged how the new expenses should be paid. The new 1765 Stamp Act and 1767-1768 Townshend Acts provoked colonial opposition and unrest, leading to the 1770 Boston Massacre and 1773 Boston Tea Party.
