Wrong.
The armies of Ferdinand and Isabella that pushed the Muslims out of the Iberian peninsula were funded in large part by the JEWS. There were many pre-Lutheran dissenters, proto-Protestants, if you will, living in Iberia at the time, perhaps as many as 10%, by Torquemada’s own estimate, and they were involved in the fight to free Iberia from Mohammedan occupation.
Neither the Jews nor the dissenters at the time knew that Isabella would betray them.
Actually, the sad thing was that a lot of the Jews did support the Muslims. This was because of their Middle Eastern connection. It was also because the Muslims just saw them as a source of money and usually didn’t care if they converted, although this changed at times and sometimes there was more pressure. For example, Maimonides converted to Islam, only to reconvert to Judaism when he escaped.
Spain before that time had the Roman system: Jews lived in their areas, and since they were not Christians or people from a defined area that paid taxes, they were therefore considered foreigners and paid the foreigner tax. The Romans had done likewise centuries before, and when you look at Spain, you have to remember Rome before the Germanic invasions.
Visigothic law in Spain was very anti-Semitic, but was never enforced. The Visigoths were Arians, that is, not orthodox Christians.
It was also because of the middle-class, low-level nobility uprisings against Jews throughout Spain, since this group perceived Jews as being favored by the Spanish court, particularly by Isabella, and felt that “pure-blood” Spaniards were being ignored.
The court under Isabella and Ferdinand had large numbers of Jews (both conversos and practicing Jews) in important positions, but after the riots, Isabel felt that the Crown simply couldn’t protect the Jews.
The Jews all had to leave but were given appraisals and receipts for their properties. Later on, when the properties were sold, these were made good if the owner could be found.
Protestants had nothing to do with this. That was an entirely different matter. “Luteranos” were perceived as destroying the unity of Christendom, particularly in its fight against Islam, since Luther was actually an admirer of Mohammed and even, at the end of his unhappy life, was in favor of polygamy.
