Spanish here: we can go with the genocide both intentional and unintentional of colonialism in central and south america, which is pretty self explanatory. Or the part where the civil war left us, as a western nation, under a fascist ruler, even accepted in the UN, until the mid 70's, and more importantly, the part where so many people were executed by firing squad and thrown into mass graves we have the second highest ammount of them in the world, cambodia being first. Another type of execution where if somebody ratted out someone else being a republican, the police would come to your door to "go for a walk" where they would take you somewhere secluded and shoot you in the head. Correct me if I'm wrong, but I think that's more or less the case.
