But I see a lot of comments here about what Fanquismo was and wasn't, and I believe it comes out of ignorance about Spanish history. Many comments here make it look like this was a choice between Franquismo/Fascism and personal freedom and democracy. It wasn't. It was a brutal struggle between Fascists and Communists, and good people that wanted freedom were caught in the middle right since the beginning. The choice wasn't between Fascism or Democracy, the choice was just between two major evils: Fascism or Communism and that's why it divided Spanish society
It can be argued that when this happened (1968), the bloody and brutal Spanish Civil War (that started with major violent acts from the communists' side after fair elections, BTW) was long over and the country should already be way on the path to democracy (and I agree if that was the point being made), but let's not pretend that she joined good company and proper people that just wanted to liberate Spain.
People commenting here really need to read about the Spanish Civil War to understand how it went down. Communists were so destructive that in the middle of the war, they started fighting and killing each other instead of fighting against the Fascist forces. Major atrocities were committed on both sides. POWs were routinely rounded up and executed, both by the Communists and by the Fascists.
The only group that seemed to have some sense when it came to defend basic humanity were the anarchists (although they did have a lot of other issues). Read Homage to Catalonia by George Orwell for a beautiful and sad description of a small part of this conflict.
There's this old 6 episodes TV Series from 1983, that really gives a good perspective of how awful it all was: https://www.youtube.com/watch?v=M_I6C-VbFvI
