The Enlightenment was a pivotal period beginning in the 17th century that emphasized reason, natural rights, and equality, challenging traditional authority and leading to significant societal changes, including the advocacy for women's rights. Key philosophers like John Locke and Voltaire promoted ideas about government, freedom of speech, and social contracts, which contributed to foundational democratic documents such as the U.S. Constitution and the Declaration of the Rights of Man. This intellectual revolution encouraged individuals to think critically, question established norms, and seek a fair and just society.
