In the "The Twentieth Century" section the side of Franco is called "Nationalist forces" which is not a correct translation of the spanish term, the correct one would be "National forces". I would also change the statement "under Franco's regime" by "under Franco's dictatorship" and that would be far more true, in order to inform about the period to an unknowing reader in such few lines. 

 A curious fact about early XX century in Spain, the dictatorship of "Primo de Rivera" (here called "autoritarian rule", strange for a government imposed after a military coup) was openly called in that period "dictablanda" as opposed to "dictadura", the spanish for "dictatorship", which from Spanish literally translates as "dictator-hard", so that "dictablanda" means "dictator-soft" because it didn't feel like a true dictatorship. 

 It is sad to have so much dispute about the Civil War's causes and Franco's regime so as to not mention almost anything in this article, very sad. Were I to write it, I'd mention that the Civil War started after very hard political disputes between right and left-wing parties which led to violence in the streets and selective murders of political opposites (remember Europe was immersed in that violence everywhere, Germany was a similar case, with nazis and communists disputing the streets). 

 Truth is the Civil War started with a military coup led by, among other military men, general Francisco Franco. I personally understand why they did it but I can't absolutely agree with anybody attacking a democracy, independently of its frailness. The result was a dictatorship with no democracy and without many freedoms (reunion, information, ...) that lasted from 1939 to 1975 (Franco's death). 

 This "regime" follows to the letter the most pure definition of a dictatorship and nobody can be offended by it and try to deny here that truth. Also to say that the Civil War was started by a military coup against the Republic's left-wing government is undisputable. 
 To discuss the "reasons" why it was done does not avoid saying who started a civil war against the internationally recognized government of Spain before the war (the Republican government). 
 In this Civil War both sides committed abominable crimes, as always happens in Civil Wars were the situation is not one country invading a different one, it is half a country trying to destroy and prevail over the other half, it is an inner war where both sides are fighting for their own country (and political views, we must always remember the immense hatred against opposites in that part of XX century), which makes it fierce and merciless. 

 To be fair it must be stated that under the almost forty years of Franco's dictatorship there was a period of economic growth and construction/modernisation of vital infrastructures (mostly in the later years, after Spain started being seen as an ally against Soviet Union and received important amounts of money from USA). It is also true that after the Civil War Spain was a devastated country (as much as its own soul, it was a true brothers' war), which was also a good reason not to join Hitler and Mussolini's campaigns. 

 Very fierce and inhuman retaliation was conducted by the winners of the civil struggle, the National side, in the early years after the war (which lead to a partisan movement that was joined in 1945 by returning Republican soldiers that had escaped Spain and kept fighting fascism with the Allies, inside French units, as the Leclerc division and the French Foreign Legion). 

 During all the period, fear was widespread among people with political views distinct to that of the regime, and had to act in clandestinity. Censorship was the rule. 

 About Spain's position in WW2 it can be said that not only Spain exported wolfram to Nazi Germany (which was used in anti-tank shells) but also that a military formation of some thousands of volunteers called "División Azul" (Blue Division, as blue was the color of the Nationals, as opposed to the red of the left-wing adversaries in the Civil War) was attached to the German Wehrmacht (Army) and served in the Russian campaign. It was formed mostly by fierce anti-bolshevists and there were also some people whose position, or their families', in the Civil War was doubtful to the view of the winners and volunteered in order to be accepted by the regime. Curiously, having such a different culture than the German Army, Spanish soldiers were not badly regarded in the Russian towns where it mingled in the frontlines.
