How did Enlightenment ideas influence revolutions in the 18th and 19th centuries?

• A. Emphasized monarchy and divine right.
• B. Promoted religious tolerance above all.
• C. Encouraged social equality.
• D. Emphasized liberty, equality, and popular sovereignty, inspiring revolutions.

Answer: (D)

Enlightenment thinkers argued that people have natural rights and that governments exist to protect those rights, deriving authority from the consent of the governed. When rulers claimed absolute power or justified rule by birth, these ideas suggested political change could be legitimate. This made revolutions appealing as a way to establish governments based on liberty, equality, and the will of the people. Across the 18th and 19th centuries, such ideals fueled efforts to create constitutional limits on power, representative institutions, and the rule of law, driving movements like the American and French Revolutions and later independence struggles in Latin America and Europe. Religious tolerance and social reform were part of Enlightenment thought, but the longstanding impulse behind revolutions was the push for liberty, equality, and popular sovereignty—government by the people rather than by hereditary claim or divine right.
