The French Revolution, which began in 1789, caused significant societal upheaval by challenging the established social and political order. It marked the decline of absolute monarchy and the rise of republicanism, fueled by Enlightenment ideals of liberty, equality, and fraternity. The revolution led to widespread political chaos, social reorganization, and violent periods such as the Reign of Terror. It dismantled feudal structures and created a radical shift in power, as ordinary citizens gained political agency. The revolution inspired future democratic movements worldwide, symbolizing both the possibilities and challenges of revolutionary change in society.
