So fell the uprising, with great violence upon the rebels, but also with great unity and revolutionary fervor amongst the working classes. The crushing of the revolt was led by General Francisco Franco, who would later lead a rebellion against the republic and become dictator of Spain. The use of the Foreign Legion and the Moorish to kill Spaniards caused public outrage. Captured miners faced torture, rape, mutilation, and execution. This foreshadowed the same brutality seen two years later in the Spanish Civil War. Popular Front With the growth of right-wing political parties (Gil Robles' conservative Spanish Confederation of the Autonomous Right, for example), leftist parties felt the need to join together in a "Popular Front." This included Republicans, Socialists, Communists, and other left parties; Anarchists were not willing to support it but refused to attack it, either, thus helping it get into power. The more radical elements of the CNT-FAI were not satisfied with electoral politics. In the months after the Popular Front's rise to power, strikes, demonstrations, and rebellions broke out throughout Spain. Throughout the countryside, almost 5 km2 of land were taken over by squatters. The Popular Front parties began to lose control. Anarchists would continue to strike even when prudent socialists called it off, taking food from stores when strike funds ran out. The CNT's national congress in May 1936 had an overtly revolutionary tone. Among the topics discussed were sexual freedom, plans for agrarian communes, and the elimination of social hierarchy. Individualist anarchism Spanish individualist anarchism was influenced by American individualist anarchism but it was mainly connected to the French currents. At the start of the 20th century people such as Dorado Montero, Ricardo Mella, Federico Urales, Mariano Gallardo and J. Elizalde translated French and American individualists. Important in this respect were also magazines such as , , , , , , and . The most influential thinkers there were Max Stirner, Émile Armand and Han Ryner. Just as in France, Esperanto, anationalism, anarcho-naturism and free love were present as philosophies and practices within Spanish individualist anarchist circles. Later Armand and Ryner started publishing in the Spanish individualist press. Armand's concept of amorous camaraderie had an important role in motivating polyamory as realization of the individual. Historian Xavier Diez wrote on the subject in . deals with free love thought in . Diez reports that the Spanish individualist anarchist press was widely read by members
