The French Revolution began due to financial crisis and resentment from the Third Estate towards the unequal system dominated by the First and Second Estates. This led commoners to storm the Bastille and establish the National Assembly. The Assembly abolished feudalism and adopted the Declaration of Rights of Man, establishing a constitutional monarchy. However, as unrest grew, the monarchy was overthrown and the radical Reign of Terror installed, during which Robespierre had thousands executed. The Revolution ultimately gave way to the rise of Napoleon Bonaparte as leader of France.
