The document summarizes the key events leading up to and during the Spanish Civil War from the early 1920s to 1936. It discusses the divisions within Spanish society that weakened the government and led to a military coup in 1923. Economic troubles in the late 1920s further destabilized the country and led to a republic being declared in 1931. Attempts at reform sparked opposition and unrest between left and right-wing groups. This political instability resulted in an army revolt in 1936 launching the Civil War, with Nationalists led by Franco fighting Republicans of varied left-wing affiliations.
