The Enlightenment period was significant in shaping modern political thought as it emphasized reason, individualism, and skepticism of traditional authority. Philosophers like John Locke, Voltaire, and Montesquieu championed ideas such as natural rights, separation of powers, and the social contract, laying the groundwork for democratic governance and civil liberties. The Enlightenment challenged the divine right of kings and absolute power, advocating for the rights of individuals and the importance of reasoned debate. Its impact influenced revolutionary movements, including the American and French Revolutions, ultimately shaping modern democratic ideals and institutions.
