the execution of Louis XVI by guillotine on Monday, January 21, 1793, followed by the "Reign of Terror", mass executions and the provisional "Directory" form of republican government, and the eventual beginnings of twenty-five years of reform, upheaval, dictatorship, wars and renewal, with the various Napoleonic Wars. Restoration Following the French Revolution (1789–99) and the First French Empire under Napoleon (1804–1814), the monarchy was restored when a coalition of European powers restored by arms the monarchy to the House of Bourbon in 1814. However the deposed Emperor Napoleon I returned triumphantly to Paris from his exile in Elba and ruled France for a short period known as the Hundred Days.

Under his reign, the censorship of newspapers was reinforced, the Anti-Sacrilege Act passed, and compensations to Émigrés were increased. However, the reign also witnessed the French intervention in the Greek Revolution in favour of the Greek rebels, and the first phase of the conquest of Algeria. The absolutist tendencies of the King were disliked by the Doctrinaire majority in the Chamber of Deputies, that on 18 March 1830 sent an address to the King, upholding the rights of the Chamber and in effect supporting a transition to
