I’m not willing to give Franco even that, It was international pressure that pressured Franco and then the king to try a different path. It is just rationalization after the fact that makes many right wingers come with the idea that Franco brought the monarchy to bring democracy back, I have seen enough evidence to say that Franco wanted to bring back the monarchy because he thought it would be the only way to continue his vision of a non-democratic, intolerantly Catholic, and deeply reactionary Spain, with a military dictator as the real power behind the throne. Unfortunately the designed by Franco’s successor was murdered and then Franco died. The King, after seeing the writing on the wall, (lots of unrest in favor of change) then changed his tune.
Democracy finally came to Spain by despising the will of Franco.
