Cue the Inquisition Deniers. They are FReepers who are Roman Catholic sycophants, convinced that to be Jewish or Protestant in Portugal and Spain was actually a good thing. Or the other tactic is to say the horrors were not instituted by the “church.” Yeah, and ISIS is not Islamic...
We often think of the Roman Inquisition as being far in the past. But it was very active in WWII, and its office in the Papacy remains open even until this very day. The name has been changed. The Concordat was agreed to by Yugoslavia and the Vatican is well documented. This laid the groundwork for the agreement between German, Yugoslavia, and the Vatican.
Toby Green, himself a Catholic and historian is not critical, but is rather dimly a documenter in his book "Inquisition". He documents not only the Spainish and Portugal inquisitions but that of Mexico , central and south America, north Africa, and eastern Asia.
Green states the number of deaths at the direction of the Vatican rivals the number of deaths by Mao and Stalin, albeit over a period of 600 years.
Some consider the Roman Inauisition as the darkest hours of the earth. Green estimated between 50 and 100 million were murdered at the order of the Vatican, although Green (catholic) believes the number to be closer to the higher of those two estimates.
