republican democratic goverment

national side, leaded by the fascist general franco

this war became a proxy war in which european powers tested their military equipment. on one side, urss and mexico supported the left-wing republican spanish goverment, while nazi germany and fascist italy supported the national fascist side.

franco managed to win the war in 1939, with the significant contribution of the foreign military support, and became the dictator of spain until his death in 1975.
