Although the Left won the 1906 legislative election, the Socialists did not repeat their alliances with the Radicals and the Radical-Socialists and other Republican forces.
[3] Following the Dreyfus Affair, Pierre Waldeck-Rousseau assembled a "Republican Defense Cabinet" (gouvernement de défense républicaine) in June 1899, which was supported by a parliamentary majority composed of Radicals, Radicals-Socialists and Socialists.
Under Emile Combes's leadership, the new government enacted an anti-clerical policy, passing the 1905 French law on the Separation of the Churches and the State, and opposed itself to the nationalist movement.
[5] "Opportunist Republicans" who opposed the alliance with the Radicals, the Radicals-Socialists and the Socialists, and, for some of them, the defense of the Jewish officer Alfred Dreyfus, founded in November 1903 the Republican Federation (Fédération républicaine), which represented the Republican bourgeoisie, closely connected to business circles and opposed to social reform.
[7] The Socialist ministers thereafter withdrew themselves from the Republican Coalition, which dissolution was completed in October 1906 with the coming of Georges Clemenceau to power.
