The Enlightenment influence on political revolutions 1750-1900 transformed how people thought about government, human rights, and society. This intellectual movement emphasized reason, individual liberty, and progress.
Key figures of the Scientific Revolution like Galileo Galilei, Isaac Newton, and Francis Bacon developed the scientific method and made groundbreaking discoveries about gravity, motion, and the natural world. Their work showed that careful observation and experimentation could reveal nature's laws, challenging traditional authorities and encouraging people to question established beliefs. This new way of thinking spread beyond science to influence politics and society. Philosophers began applying scientific reasoning to understand human nature and government.
John Locke's natural rights and social contract theory had an especially profound impact. He argued that all people are born with natural rights to life, liberty, and property that no government can take away. Locke proposed that legitimate government power comes from the consent of the governed through a social contract - people agree to obey laws in exchange for protection of their rights. These ideas inspired revolutionary movements, including the American and French Revolutions. The Declaration of Independence and U.S. Constitution reflect Enlightenment principles about individual rights and limited government. Similarly, the French Revolution's Declaration of the Rights of Man and Citizen was shaped by Enlightenment ideals about equality and liberty. This period saw old systems of absolute monarchy and inherited privilege give way to new forms of government based on popular sovereignty and constitutionally protected rights. The Enlightenment's emphasis on human reason, progress, and natural rights continues to influence modern democratic values and institutions.
