What made it possible
- The Seven Years' War had doubled Britain's debt and removed France from North America, which encouraged London to make the colonies pay for their own defence.
- The 1765 Stamp Act and the 1767 Townshend duties established the principle of parliamentary taxation of the colonies, which the colonists rejected as unconstitutional rather than merely burdensome.
- The 1773 Tea Act and the Boston Tea Party produced the Coercive Acts of 1774, which closed the port of Boston and revoked Massachusetts's charter.
- The 1775 battles at Lexington and Concord and the appointment of Washington as commander turned a constitutional dispute into an armed conflict before independence was declared.
Who acted
- Thomas Jefferson
- Thirty-three years old when he drafted the declaration; his draft included a clause condemning the slave trade that was removed
- George Washington
- Commander of the Continental Army; kept an army in being for eight years without winning most of its battles
- King George III
- Regarded the rebellion as a conspiracy to be suppressed and rejected the 1775 Olive Branch Petition
- Comte de Rochambeau
- Commanded the French force at Yorktown; French naval control of the Chesapeake decided the campaign
A war for jurisdiction, not for representation alone
The colonists' argument was not that they were unrepresented in a practical sense — several colonies did have agents in London — but that Parliament had no jurisdiction over them because they had their own legislatures. This is why the declaration's list of grievances reads like an indictment: it charges the king with assenting to legislation that dissolved representative assemblies, with transporting accused colonists overseas for trial, and with maintaining standing armies in peacetime.
The declaration was also a diplomatic instrument, written partly for a French audience. The 1778 treaty of alliance that followed Saratoga is what turned the war: French naval power made Yorktown possible, and French loans paid for the army that marched there.
How the war was actually won
Washington lost most of the battles he fought. What he did was keep an army in the field through winters at Valley Forge and Morristown, which prevented the British from ending the war by capturing a single force. The British for their part never found a way to hold territory beyond the ports they garrisoned, and their 1777 plan to isolate New England failed at Saratoga.
The decisive factor was the French alliance and, from 1779, Spanish and Dutch involvement, which stretched the Royal Navy across the Atlantic, the Caribbean and the Indian Ocean. At Yorktown in 1781, about 7,000 British troops surrendered to a combined American and French force after the French fleet closed the Chesapeake — a naval outcome, not an infantry one.

The sentence that outlived the war
The second paragraph's assertions — that all men are created equal and that governments derive their just powers from the consent of the governed — were not new ideas. What was new was the act of founding a state on them in a written document, which made the failure to apply them a permanent political problem rather than a philosophical one.
The abolitionist movement, the women's rights convention at Seneca Falls in 1848, Lincoln's Gettysburg Address and Martin Luther King's 1963 speech all argue from that paragraph against the practice of the government that issued it. That is the declaration's real historical role: it supplied the standard by which the United States has been measured ever since, including by its own citizens.
Consequence: short and long
Immediately
The United States was recognised as an independent state in 1783, and the political vocabulary of the declaration spread through the Atlantic world.
Over the long run
The declaration's practical legacy was constitutional rather than military: it asserted that legitimate government rests on consent, which the 1787 Constitution then had to institutionalise, and which was invoked by the Haitian revolutionaries in 1791, by Latin American independence movements after 1810, and by the Seneca Falls convention in 1848. The document's internal contradiction — declaring equality while the signatories held about 500,000 people in slavery — was noted immediately, including by British pamphleteers and by enslaved petitioners in Massachusetts, and became the central argument of American abolitionism.
The usual misconception
That the declaration was the beginning of the war or that it was universally popular. Fighting had been going on for fourteen months, and the vote on 2 July was contested: New York abstained and the Pennsylvania and South Carolina delegations were split. The document's function was to obtain foreign allies, specifically France, which is why the grievances listed are framed as violations of law rather than as grievances about policy.
