Armed conflict broke out in northern Mexico, led by Madero, Pascual Orozco, and Pancho Villa, and with support from portions of the middle class, the peasantry, and organized labor, Díaz was forced out. In the Treaty of Ciudad Juárez, Díaz resigned and went into exile. New elections were held in 1911, and Madero was elected, taking office in November. Opposition to his regime then grew from both the conservatives, who saw him as too weak, and from former revolutionary fighters, who saw him as too conservative.
