The Enlightenment significantly impacted Western political thought by promoting ideas of reason, individualism, and skepticism towards traditional authority. Philosophers like John Locke argued for natural rights and the social contract, influencing democratic principles and inspiring revolutionary movements. These Enlightenment ideals questioned the divine right of kings and fueled the development of constitutional government, separation of powers, and the notion of government accountability to the governed. This intellectual movement laid the groundwork for modern democracies and influenced key historical events, such as the American and French revolutions, fostering a belief in the capability of human reason to create a more just society.
