Does that count the Crusades and the Spanish Inquisition? I seem to remember they did their best to rid the world of Jews back then.

Inquisition did not physically harm Jews, it just deported them, sort of like what many Tea party COnservatives want to do with illegal immigrants here today. Forcibly deport them back to Mexico. The Spanish Inquisition was secular courts that theologians participated in to determine if someone was an orthodox Catholic or not. Jews, and Muslims were not brought to it. Now, the Muslims were the ones that the Catholic Spaniards were fighting in the war of reconquest, which finally ended in 1492 or there abouts. The Muslims were driven out, the Jews were given 3 months to leave, some converted to Christianity, no Jew was tried in the Inquisition.
Whig History from England. As for the Crusades, they were lawful wars to deal with Muslim aggression, and they were not called to go after Jews. Some of the Crusaders, particularly in Germany, did attack innocent Jews, and they were called out for it. that is the problem with all Wars, sometimes, soldiers do bad things. Most of the Crusaders fought honorably against the Mohamadens.
The Catholic preservation of Jewish Scriptures and worship traditions (such as cantillation) occurred ~1,000 years before the time period you reference.
