The main political ideology promoted during the French Revolution was liberalism, emphasizing liberty, equality, and fraternity. The revolution sought to dismantle the feudal system and aristocratic privileges, advocating for individual rights and participation in government. The ideas of John Locke and Jean-Jacques Rousseau heavily influenced revolutionary leaders, leading to the establishment of democracy and secularism in France. The revolution also highlighted class struggles and fueled movements across Europe, representing a dramatic shift from royalist absolutism to modern democratic governance.
