Absolute monarchs during the 1500s-1700s believed in the divine right to rule and governed strictly, causing conflicts and unrest among the people. An example was Louis XIV of France, who spent lavishly on Versailles while the people struggled. During the Enlightenment period from the 1600s-1700s, thinkers developed new ideas about government and individual rights that challenged absolute rule, including John Locke's ideas about natural rights, Montesquieu's separation of powers, and Rousseau's concept of consent of the governed. The spread of these Enlightenment ideas led the people to increasingly question monarchal rule and fight for more freedoms, setting the stage for revolution.
