The history of modern Spain is dominated by the figure of Francisco Franco, who presided over one of the longest authoritarian regimes of the twentieth century. Between 1936 and the end of the regime in 1975, Franco’s Spain passed through several distinct phases of political, institutional, and economic development, moving from the original semi-fascist regime of 1936–45 to become the Catholic corporatist “organic democracy” under the monarchy from 1945 to 1957. Distinguished historian Stanley G. Payne offers deep insight into the career of this complex and formidable figure and the enormous changes that shaped Spanish history during his regime.
