Who came up with the idea all men are born with natural rights?

The idea that all men are born with natural rights is most notably associated with the Enlightenment philosopher john Locke. In his work "Two Treatises of Government," published in 1689, Locke argued that individuals possess inherent rights to life, liberty, and property, which are not granted by governments but are intrinsic to human nature. This concept significantly influenced modern political thought and the development of democratic principles.
