Of the radical and revolutionary groups in Paris at the time of the Commune, the most conservative were the "radical republicans". This group included the young doctor and future prime minister Georges Clemenceau, who was a member of the National Assembly and Mayor of the 18th arrondissement. Clemenceau tried to negotiate a compromise between the Commune and the government, but neither side trusted him; he was considered extremely radical by the provincial deputies of rural France, but too moderate by the leaders of the Commune.
