Ken Burns on Why America Really Declared Independence

The Declaration's natural-rights language expanded narrow political disputes into a lasting rights movement because wording like 'all men are created equal' reframed grievances as universal claims that marginalized groups could use to press for abolition and wider enfranchisement over time.

French military intervention made American victory possible because French fleets blocked British relief at the Chesapeake and their forces trapped Cornwallis, enabling the decisive siege at Yorktown.

Washington's vital strategic contribution was keeping the Continental Army alive because by avoiding capture and trading space for time he turned tactical defeats into a war of attrition that drained British resources and political will.

Atlantic distance limited Britain's ability to control the colonies because slow sailing-era communication, long resupply lines, and weak force projection made rapid governance and sustained military response impractical.

Mutual accusations of tyranny radicalized both sides because labels and punishments provoked harsher reactions in turn, creating a self-reinforcing cycle that pushed conflict from dispute to open war.

Imperial taxes mattered less as a pure burden and more because metropolitan levies and trade rules disrupted local economies and smuggling networks that colonists had long relied on, making the taxes feel illegitimate.

Access to land drove American separatism because settlers and new immigrants wanted westward farms and the 1763 Proclamation Line forbidding expansion converted that desire into a direct political grievance.
