How would the ideas presented by the philosophers(John Locke, Thomas Hobbes, Jean-Jacques Rousseau) be a motivation for the French people to revolt against the monarchy?

Ideas John Locke, Thomas Hobbes, and Jean-Jacques Rousseau helped popularized the concept of Democracy. (hobbes actually supported absolute monarchy in general, but several of his ideas are implemented in Democracy)

Explanation:

John Locke was known for his ideas about law supremacy. No one should be placed above the law. Even the government officials should be subjected to the same law as the people.

Hobbes presented the idea that The government exist only to represent the interest of the people who form them. Especially to maintain order, economic stability and safety from foreign attack.

Jean-Jacques Rousseau presented the idea that The government should guarantee the freedom of its people.

The combination of these ideas contributed to the democratic ideology that we used today, This exact ideology was held by the people of France when they revolted against the monarchy. They no longer wanted the government ruled by nobles. They wanted the people to be influenced in determining the policies taken by the government.
