Louis-Eugène Cavaignac, (born Oct. 15, 1802, Paris—died Oct. 28, 1857, Sarthe, Fr.), French general and chief executive during the Revolution of 1848, known for his harsh reprisals against rebelling Parisian workers in June of that year.
Cavaignac’s father, Jean-Baptiste, was a Jacobin member of the Committee of General Security during the French Revolution (1789– 92), and Louis retained his father’s strong republican beliefs. His uncle, Jacques-Marie, served the Bourbons and the July Monarchy, which ruled France in 1830–48, and helped Cavaignac regain his appointment in the army, from which he had been dismissed in 1831 because of his republicanism. Nevertheless, he was sent to the relative isolation of Algeria.
Cavaignac performed with distinction during the French conquest of Algeria in the 1840s, and in 1848 he was appointed governor general. Amid the revolutionary activity of that year, he was elected to the legislature in France and appointed minister of war by the provisional government of the newly formed Second Republic. That June there was a large workers’ revolt in Paris to protest the expulsion of Socialist leaders from the National Assembly and the closing of the national workshops (government-sponsored employment centres). Cavaignac directed the suppression of the revolt, for which he became known as “the butcher of June.” On June 28 the National Assembly named him chief executive of France, but he lost the presidential election to Louis-Napoléon Bonaparte (later Emperor Napoleon III) that December.
Cavaignac remained a leader of the opposition to Bonaparte. He was arrested in 1851, but the next year he was elected to the Corps Législatif. He refused, however, to take an oath of allegiance to the new emperor and thus was denied his seat in the legislature both then and again in 1857.
In 1899 the memoirs and correspondence of Cavaignac and his uncle were published as Les Deux Généraux Cavaignac. Souvenirs et correspondance (1808–1848).
