Why Britain's Grip on the American Colonies Slipped

Six fractures widened the Atlantic rift:

1. Colonial Maturity — Assemblies, courts, militias, trade networks—self-governance muscle memory.
2. Economic Extraction — Navigation Acts, Sugar Act, Stamp Act, Townshend Acts: revenue for Britain, restraint for colonies.
3. Enlightenment Ideas — Locke, Montesquieu, Paine: consent, rights, representation—colonists read them; Parliament ignored them.
4. No Vote in Westminster — "Virtual representation" satisfied no one in Boston or Philadelphia.
5. Frontier Friction — French & Indian War (1754–63) cost blood and treasure; Proclamation of 1763 blocked western lands colonists fought for.
6. Post-War Heavy Hand — Standing army quartered, writs of assistance, tea monopoly—each act a provocation.

By 1775, the bond was constitutional theory vs. lived reality. The shot at Lexington settled the argument.
