Oil

Explanation:

Ever since oil was discovered and used in the world most of it came from the Middle East. Many wars were fought over who controls that area of the world and are still being fought today.

republican democratic goverment

national side, leaded by the fascist general franco

the spanish civil war took place between 1936 and 1939 and was fought after a military coup undertaken on the 17th july 1936 by a group of generals that had seceeded from the spanish republican army, under the leadership of general franco, and who aimed to expel the democractically-elected republican goverment from power.

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.
