“The Red Terror death toll has been estimated at 40k to 110k.”
40K is an absurd figure when you realize they have the names of 7K priests alone that were murdered.
Rummel puts the mid-level estimate of Democides for both sides at about 100k each during the war years. Then he has another 275K for Franco 1939-1975, most of which I would guess would be in post-war purges.
I’ve always though Rummel reasonably unbiased by politics.

I was reporting the estimates, not making my own.
