Who was the US President during the Spanish Civil War?

General Francisco Franco, who was a fascist dictator was head of the government, but also declared himself 'regent' ruling on behalf of the King who was not permitted to take the throne. When Franco died, he declared in his will that the monarchy should be restored, which duly happened in 1975 with King Juan Carlos I taking the crown. The King of Spain went about introducing democracy and a constitution and elections were enacted in 1978.
