The Enlightenment philosophers inspired the American and French Revolutions, advocating for reason, individual liberty, and democratic governance. Their ideas challenged traditional monarchies and inspired citizens to seek self-determination and social reform. In America, Enlightenment principles shaped the Declaration of Independence and Constitution, emphasizing rights such as life, liberty, and the pursuit of happiness. In France, thinkers like Rousseau and Voltaire ignited revolutionary thoughts that culminated in the French Revolution, advocating against feudalism and the absolute monarchy. Thus, the Enlightenment played a crucial role in promoting revolutionary ideals that transformed societies and laid the groundwork for modern democracy.
