Taxation Without Representation: The Stamp Act
Deep in debt after the Seven Years' War (the French and Indian War), which ended in 1763, Britain looked to its American colonies for revenue. In 1765 Parliament passed the Stamp Act, requiring colonists to buy a government stamp for newspapers, legal documents, and other paper goods. Colonists, who had no representation in Parliament, denounced it as taxation without their consent.
Why it matters: The cry of 'no taxation without representation' united the thirteen colonies in protest for the first time and set colonists and crown on the road to revolution.

The Boston Massacre
On the night of 5 March 1770 a crowd taunted and pelted British soldiers stationed near the Old State House in Boston. The soldiers opened fire, killing five colonists, among them Crispus Attucks, a man of African and Native American descent.
Why it matters: Publicized by patriots as a 'massacre,' the killings inflamed anti-British feeling and became a lasting rallying cry for the growing colonial resistance.

The Boston Tea Party
To protest a tax on tea and the monopoly granted to the East India Company, on the night of 16 December 1773 colonists — some disguised as Mohawk people — boarded three ships at Boston's Griffin's Wharf and dumped 342 chests of tea into the harbor.
Why it matters: The defiant destruction of the tea provoked harsh British reprisals and pushed the colonies toward open confrontation.

The Intolerable Acts and the First Continental Congress
Britain answered the Tea Party with the Coercive Acts of 1774 — called the 'Intolerable Acts' in America — which closed the port of Boston and curtailed Massachusetts self-government. In response, delegates from twelve colonies met in Philadelphia in September 1774 as the First Continental Congress to coordinate resistance and organize a boycott of British goods.
Why it matters: The Intolerable Acts turned a local quarrel into a common cause, and the Continental Congress became the body through which the colonies would soon wage war and declare independence.
- April 19, 1775Reputable sourceWell documented
Lexington and Concord
On 19 April 1775 British troops marched from Boston to seize colonial arms at Concord. Militia met them at Lexington, where a shot — the 'shot heard round the world' — began the fighting, and again at Concord's North Bridge, from which the British were driven back to Boston under fire.
Why it matters: Lexington and Concord were the first battles of the American Revolutionary War, turning a decade of protest into armed rebellion.

The Battle of Bunker Hill
On 17 June 1775 British forces assaulted colonial fortifications overlooking Boston, in fighting centered on Breed's Hill. The British eventually took the ground but suffered heavy casualties against the entrenched Americans.
Why it matters: Though a British victory, Bunker Hill showed that colonial militia could stand and fight against regular troops, stiffening American resolve early in the war.

Thomas Paine's Common Sense
In January 1776 Thomas Paine published Common Sense, a pamphlet that in plain, forceful language argued for a complete break from Britain and for a republic in place of monarchy. It sold in enormous numbers across the colonies.
Why it matters: Common Sense swung public opinion decisively toward independence and prepared the ground for the Declaration six months later.

The Declaration of Independence
On 4 July 1776 the Continental Congress adopted the Declaration of Independence, drafted chiefly by Thomas Jefferson. It proclaimed the thirteen colonies to be free and independent states and asserted that all men are created equal and endowed with unalienable rights to life, liberty, and the pursuit of happiness.
Why it matters: The Declaration announced the birth of the United States and set out an ideal of human equality and government by consent that would echo through American history — and inspire revolutionaries abroad.

Washington Crosses the Delaware
After a demoralizing string of defeats, on the night of 25–26 December 1776 George Washington led the Continental Army across the ice-choked Delaware River in a winter storm and surprised the Hessian garrison at Trenton, New Jersey, the next morning, capturing some 900 soldiers.
Why it matters: The victory at Trenton revived the sinking morale of the army and the cause at one of the war's darkest moments.

The Battle of Saratoga
In the autumn of 1777 American forces halted and surrounded a British army under General John Burgoyne in upstate New York. On 17 October 1777 Burgoyne surrendered his entire force — the first surrender of a British army in the war.
Why it matters: Saratoga is regarded as the turning point of the Revolution: the stunning American victory convinced France to enter the war as an ally.

Valley Forge
From December 1777 to June 1778 Washington's army wintered at Valley Forge, Pennsylvania, building a camp of some 2,000 huts. Disease, not battle, was the great killer, claiming around 2,000 lives; meanwhile the Prussian officer Baron von Steuben drilled the soldiers into a more disciplined force.
Why it matters: The ordeal at Valley Forge became a symbol of American perseverance, and the army that marched out was better trained and more professional than the one that had marched in.

The French Alliance
Persuaded by the American victory at Saratoga, France signed a Treaty of Alliance and a Treaty of Amity and Commerce with the United States on 6 February 1778, negotiated in part by Benjamin Franklin. France recognized American independence and pledged not to make a separate peace with Britain.
Why it matters: French money, troops, and above all naval power transformed the war and proved decisive in the campaign that ended it.

The Siege of Yorktown
In the autumn of 1781 Washington's combined American and French armies trapped General Cornwallis's British force on the Yorktown peninsula in Virginia, while a French fleet cut off escape or rescue by sea. After weeks of bombardment, Cornwallis surrendered more than 7,000 men on 19 October 1781.
Why it matters: The defeat at Yorktown broke Britain's will to continue the war and led directly to peace negotiations.
- September 3, 1783Reputable sourceWell documented
The Treaty of Paris
Negotiated by John Adams, Benjamin Franklin, and John Jay, the Treaty of Paris was signed on 3 September 1783. In it Britain formally recognized the independence of the United States and agreed to generous boundaries stretching west to the Mississippi River.
Why it matters: The treaty ended the Revolutionary War and confirmed the United States as a sovereign nation with room to expand.

The Constitutional Convention
In the summer of 1787 delegates meeting in Philadelphia — gathered originally to revise the weak Articles of Confederation — instead drafted an entirely new framework of government. Signed on 17 September 1787, the Constitution created a federal republic balancing executive, legislative, and judicial powers. Its provisions on representation and slavery were the product of bitter compromise.
Why it matters: The Constitution has governed the United States ever since — but its unresolved compromises over slavery left a fault line that would eventually split the nation in civil war.

The Bill of Rights
To answer fears that the new federal government would trample individual liberties, the First Congress proposed a set of amendments; ten were ratified by the states on 15 December 1791 as the Bill of Rights. They guaranteed freedoms of speech, religion, the press, and assembly, and protections in criminal cases, among other rights.
Why it matters: The Bill of Rights enshrined the fundamental liberties that remain central to American law and identity, completing the founding framework of the republic.
