ルイ・ブラン
It was the speeches of Ledru-Rollin and Louis Blanc at working-men's banquets in Lille, Dijon and Chalons that 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.
