The French had really sucky monarchs (like King Louis the Thirteenth), and frankly, they were sick of living in famine and poverty, so it was kinda like being in the right place and at the right time-- they overthrew their monarchy, now aware that they had these rights (inspired by the Enlightenment). "Liberté, Égalité, Fraternité" was the slogan. Liberty, Equality, Brotherhood = everything the monarchy wasn't.
