The Republican faction (Spanish: Bando republicano), also known as the Loyalist faction (Bando leal) or the Government faction (Bando gubernamental), was the side in the Spanish Civil War of 1936 to 1939 that supported the government of the Second Spanish Republic against the Nationalist faction of the military rebellion. The name Republicans (republicanos) was mainly used by its members and supporters, while its opponents used the term Rojos (Reds) to refer to this faction due to its left-leaning ideology, including far-left communist and anarchist groups, and the support it received from the Soviet Union. At the beginning of the war, the Republicans outnumbered the Nationalists by ten-to-one, but by January 1937 that advantage had dropped to four-to-one. Source: Wikipedia (en)
