The French Revolution was a 1789 revolution which began the modern era. In a sequence of upheavals, it saw the downfall of King Louis XVI, rise of Robespierre and the Reign of Terror, a chaos wherein thousands were guillotined for political differences.
Radicals saw the Catholic Church as the enemy and promoted in its place a Cult of Reason. The Revolution emerged in part from the rationalism of the Enlightenment which distrusted all established institutions. It inspired fear into European monarchs and aristocrats as well as conservative intellectuals like Edmund Burke in Britain, who mobilized to fight the Revolution, and finally succeeded in 1815.
The revolution was very liberal in nature, and saw a perfect execution of the classical liberal ideas proposed by John Locke. It resulted in chaos, destruction, and radicalization, which were the very ideas that Burke and other classical conservatives had warned about. It gave the world a glimpse of what liberalism was like when put into action. Unlike the American Revolution, it had nothing to do with natural progress or change and launched a series of events that led to Europe becoming more classically liberal. These radical changes would arguably lead to more globalism as well as alliances, giving rise to World War I over a hundred and twenty years after it first began.
