The nationalist rebels who were being led by Francisco Franco managed to overthrow the government since they had a lot of support from military units that were situated in Morocco, Pamplona, Burgos, Cordova, Cadiz, Valladolid as well as in Seville. However, some key cities such as Madrid, Barcelona, and Valencia were not captured by the rebels but instead remained under the full control of the government resulting into a great division in the country.The nationalist rebels received a lot of military support from Nazi Germany and Fascist Italy who shared similar views with them while the government was backed by the U.S.S.R and Mexico. Some countries such as Britain and France decided to sit on the fence which gave U.S.S.R a lot of influence and ability to expand its control away from its neighboring countries. Despite the fact that Stalin had initially signed the Non-Intervention Agreement together with other nations such as Britain, they went ahead to provide major help to the Republicans thus becoming their main source of military resources. The U.S.S.R had thus contravened the provisions of the League of Nations to which it was party to. At the time United States was going through a lot of difficulty in its efforts to recover from the effects of the Great Depression coupled with the negative effects of World War I which had left the nation in a devastated state. Most of the leaders were of the opinion that the United States should not intervene in the situations. The U.S government at that time was at crossroads on whether to express its support for the idealistic cause of the Spanish Civil war or not to intervene at all.Franklin D. Roosevelt who was the U.S president at that time had shown support to the Republic government but he could not make any move at that time due to the conflicting interests considering the American foreign policy and the effect it will have on the members of the public.
