In 1935 she secretly crossed the Spanish border and went to the 7th World Congress of the Communist International held July 25–August 21 in Moscow. At this Congress, Georgi Dimitrov delivered a keynote speech in which he proposed an alliance with "progressive bourgeois" governments against the fascists. Under this doctrine, the Popular Front came to power in France in June 1936, suppressed the revolutionary fervour of the Communist masses and withheld aid from the Spanish Republic during the Spanish Civil War. The Non-Intervention Pact, which sealed the fate of the Republic, was introduced by Léon Blum, president of the French Popular Front, and signed on August 2, 1936, by France, Britain, Russia, Germany and Italy. Ibárruri welcomed Dimitrov's speech as vindication of the PCE's long-standing position and returned home "full of enthusiasm, determined to do the impossible to achieve a consensus among the various workers' and democratic organizations of our country.". At the same venue she was elected deputy member of the ECCI and became the second Communist figure in Spain after José Díaz, the secretary-general of the PCE.
