Voltaire's Enlightenment ideas influenced eighteenth- and nineteenth-century revolutions by challenging traditional authority and promoting the ideals of liberty, equality, and reason. His writings exposed the flaws and abuses of society, particularly those of the monarchy, the church, and the aristocracy. His advocacy for freedom of thought and expression, religious tolerance, and the separation of church and state fueled the desire for political and social change, inspiring revolutionaries around the world. Additionally, Voltaire's emphasis on reason and scientific inquiry inspired a new wave of intellectual curiosity and served as a catalyst for the development of modern political, social, and economic systems.
