Countries like the Soviet Union had much more importance
as they were the main supporters of 1934 "Asturias'
revolution" that tried to make Spain a proletarian
dictatorship and URSS satellite. Stalin will influence the
war removing Largo Caballero and putting his lackey Negrin
as leader of the republicans.
Germany also had great influence as they considered
essential not letting his enemy URSS get more power in
Spain.
This is so not true.In fact, the "Asturias Revolution" of 1934 was organized by anarquists (CNT) and social democrats (UGT) and anti-stalinist communist groups like the (BOC).
The pro-russian Communist Party in Spain had little support among Spanish workers, and it only gained power after the country was long into war and the URSS became the only international supporter of the Spanish goverment.
Germany supported the rebellion since early on because of their affiliation with the fascists ideas of the uprising in the 1936 coup-de-etat.
Your views reflect the historical revisionism of the Spanish right wing to paint Franco as someone that saved Spain from the soviets. However, the uprising was motivated by the loss of power from the Church, big land-owners and capitalists during the republic.
