Thanks to over 30 years of extensive research, the human cost of Franco's crusade against 'communism' and the Republican cleansing of 'fascists' is now broadly known: a maximum of 150,000 were executed in rebel (or 'Nationalist') Spain, including 50,000 after the Civil War, while there were 50–60,000 victims in the Republican rearguard, including over 6000 members of the Catholic clergy.
