Louis-Napoléon saw his opportunity, and organised the French coup of 1851. On the night of 1/2 December 1851, the anniversary of his uncle Napoleon's coronation in 1804 and his victory at Austerlitz in 1805, he dissolved the Chamber, re-established universal suffrage, had all the party leaders arrested, and summoned a new assembly to prolong his term of office for ten years. The deputies who had met under Berryer at the Mairie of the 10th arrondissement to defend the constitution and proclaim the deposition of Louis Napoleon were scattered by the troops at Mazas and Mont Valérien. The resistance organized by the republicans within Paris under Victor Hugo was soon subdued by the intoxicated soldiers. The more serious resistance in the "départements" was crushed by declaring a state of siege and by the "mixed commissions." The plebiscite of 20 December, ratified by a huge majority the "coup d'état" in favour of the prince-president, who alone reaped the benefit of the excesses of the Republicans and the reactionary passions of the monarchists.
