Strangely, Wikipedia quotes Lea, Henry Charles (January 1896). "Ferrand Martinez and the Massacres of 1391". The American Historical Review. 1 in claiming that 100,000 Jews in Aragon converted and 50,000 Jews in Castille alone were killed in the anti-Jewish violence of 1391. I would think these numbers are greatly exaggerated. Are there any current secondary estimates of victims and forced converts from this time other than other than a 123-year-old article?
