One significant war not fought by the US in the 1900s was the Spanish Civil War, which occurred between 1936 and 1939. This conflict involved the Republicans, who were loyal to the Spanish democratic republic, and the Nationalists, led by General Francisco Franco. While several countries provided support to the factions, the US remained officially neutral and did not send troops, although some American volunteers fought on the Republican side as part of the Abraham Lincoln Brigade. The war ended with Franco's victory and established a dictatorship in Spain that lasted until his death in 1975.
