American Revolution
A comprehensive timeline of the American Revolution from 1763 to 1791, covering the political, military, and social transformation that led to American independence and the establishment of the United States.
1763 CE - 1764 CE
End of French and Indian War
The French and Indian War concluded, leaving Britain with massive debt and new territorial responsibilities. This war's aftermath led to increased British taxation and control over the American colonies, setting the stage for colonial discontent and eventual revolution.
Royal Proclamation of 1763
The British government issued the Royal Proclamation designating territory between the Appalachian Mountains and Mississippi River as an Indian Reserve closed to settlement. This angered colonists who wanted to expand westward and failed to stop their migration.

Sugar Act Passed
Parliament passed the Sugar Act, decreasing existing customs duties on sugar and molasses but providing stricter enforcement measures. This was part of Britain's effort to raise revenue from the colonies to help pay for the costs of maintaining troops in North America.
1765 CE - 1766 CE
Stamp Act Passed
Parliament passed the Stamp Act, imposing direct taxes on the colonies for the first time. All official documents, newspapers, and pamphlets required stamps. Colonists objected not to the tax amount but to taxation without representation in Parliament, leading to the formation of the Sons of Liberty.

Stamp Act Congress
Representatives from nine colonies convened in New York City for the Stamp Act Congress. They issued a Declaration of Rights and Grievances arguing that taxation without representation violated their rights as Englishmen, establishing the principle of colonial unity against British policies.
Stamp Act Repealed
Parliament repealed the Stamp Act after colonial resistance and Benjamin Franklin's testimony about colonial contributions to the empire. However, they simultaneously passed the Declaratory Act asserting their right to make laws for the colonies 'in all cases whatsoever.'
1767 CE - 1768 CE
Townshend Acts Passed
Parliament passed the Townshend Acts, placing duties on paper, glass, and tea, and establishing a Board of Customs in Boston. The goal was to assert British authority over the colonies rather than simply collect revenue, leading to renewed colonial resistance and boycotts.

Tea Act Passed
Parliament passed the Tea Act to help the struggling British East India Company by allowing it to sell tea directly to colonists at reduced prices, bypassing colonial merchants. This threatened colonial merchants and was seen as another attempt to assert British control over colonial trade.
Boston Tea Party
Led by Samuel Adams, a group of men disguised as Indigenous people boarded East India Company ships and dumped £10,000 worth of tea into Boston Harbor. This act of defiance against the Tea Act became a symbol of American resistance to British taxation and authority.
