The French Revolution was a period of far-reaching social and political upheaval in France and its colonies that lasted from 1789 until 1799. It was partially carried forward by Napoleon during the later expansion of the French Empire. The Revolution overthrew the monarchy, established a republic, catalyzed violent periods of political turmoil, and finally culminated in a dictatorship under Napoleon who brought many of its principles to areas he conquered in Western Europe and beyond. Inspired by liberal and radical ideas, the Revolution profoundly altered the course of modern history, triggering the global decline of absolute monarchies while replacing them with republics and liberal democracies. Through the Revolutionary Wars, it unleashed a wave of global conflicts that extended from the Caribbean to the Middle East. Historians widely regard the Revolution as one of the most important events in human history.
The causes of the French Revolution are complex and are still debated among historians. Following the Seven Years' War and the American Revolution, the French government was deeply in debt.
