Alexandre Auguste Ledru-Rollin (2 February 1807 in Paris – 31 December 1874) was a French politician, a champion of the working classes who was forced into exile after the failure of the French Revolution of 1848.
The grandson of Nicolas Philippe Ledru, the celebrated quack doctor known as "Comus" under Louis XV and Louis XVI, Ledru-Rollin was born in Paris. He had just begun to practise at the Parisian bar before the Revolution of July 1830 and was retained for the Republican defence in most of the great political trials of the next ten years. In 1838, he bought for 330,000 francs Désiré Dalloz's place in the Court of Cassation. He was elected deputy for Le Mans in 1841 with little opposition; but the violence of his electoral speeches led to his being tried at Angers and sentenced to four months' imprisonment and a fine, against which he appealed successfully on a technical point.
He made a rich and romantic marriage in 1843 and, in 1846, disposed of his charge at the Court of Cassation to give his time entirely to politics. He was now the recognized leader of the working-men of France. He had more authority in the country than in the Chamber, where the violence of his oratory diminished its effect. He asserted that the fortifications of Paris were directed against liberty, not against foreign invasion, and he stigmatized the law of regency (1842) as an audacious usurpation.
Neither from official liberalism nor from the press did he receive support; even the republican National was opposed to him because of his championship of labour. He therefore founded La Réforme, in which to advance his propaganda. Between Ledru-Rollin and Odilon Barrot with the other chiefs of the "dynastic Left" there were acute differences, hardly dissimulated even during the temporary alliance which produced the campaign of the banquets.
It was the speeches of Ledru-Rollin and Louis Blanc at working-men's banquets in Lille, Dijon and Chalons that really heralded the revolution of 1848 . Ledru-Rollin prevented the appointment of the duchess of Orleans as regent in 1848. He and Alphonse de Lamartine held the tribune in the Chamber of Deputies until the Parisian populace stopped serious discussion by invading the Chamber. He was minister of the interior in the provisional government, and was also a member of the executive committee appointed by the Constituent Assembly, from which Louis Blanc and the extremists were excluded. At the crisis of 15 May, he definitively sided with Lamartine and the party of order against the proletariat.
