In the early 1940s, senior bishops used their influence to stop Franco adopting fully fascist policies. Senior figures in the Church were concerned by the repression that had happened in Nazi Germany and were therefore suspicious of the Falange. Although, the church had supported Franco's use of terror. Catholic clergy even worked with Franco's security services to root out enemies of the new regime. In return, Franco signed a Concordat which gave the Church considerable freedom from government interference.
