The French Revolution began in 1788 as King Louis XVI called the Estates-General due to France's bankrupt treasury. This led to conflict between the three estates of French society, and the formation of the National Assembly to represent citizens more equally. On July 14, 1789, the storming of the Bastille fortress by Parisians symbolized the people's growing discontent with the absolute monarchy. The Revolution then spread violence and turmoil across France as radical factions gained influence and instituted the Reign of Terror under Robespierre, sending thousands to the guillotine until his own execution in 1794. The monarchy was abolished, leaving France a democratic republic but still unstable amid conflict with other European nations.
