Why were john lockes ideas revolutionary

In his enormously renowned political theory, Locke presented the idea of governmental checks and balances, which became a foundation for the U.S. Constitution. He also argued that revolution in some circumstances is not only a right but an obligation, which also clearly influenced the Founding Fathers.

Locke's critical concept of the social contract, the natural and inalienable rights and that men are born free and equal served the colonists as a basis to justify their revolutionary thoughts and the independence.
