The French Revolution began in 1789 with the storming of the Bastille prison in Paris by revolutionaries. French society was highly unequal, with the majority of the population (the third estate) facing heavy taxation while the nobility and clergy were largely exempt. This, combined with Enlightenment ideas of equality and natural rights, led to growing unrest among commoners and the middle class. The Revolution abolished the monarchy and feudal system of France, establishing a constitutional monarchy then a republic, with the execution of King Louis XVI. A period of violence known as the Reign of Terror followed, led by Robespierre, before a Directory government was established under Napoleon Bonaparte.
