That would seem a cogent question. I don't know if Jews need be the only one to offer an answer but it does beg an answer.
I know I have found it curious enough to wonder why.
Why did Portugal and Spain turn the Jews out?
Why did England drive out the Jews in 1290?
Why did France push away the Jews in 1306 and again in 1394?
Why did Belgium exile the Jews in 1370 and Czechoslovakia exiles them in 1380?
Why did Holland drive out the Jews in 1444?
Why did Italy turn the Jews out in 1540?
Why did Germany push the Jews out in 1551?
Why did Russia exile the Jews in 1510?
If cogent answers are not forth coming perhaps at least opinions can be shared and discussed. There had to be a reason. We could even discussion why no answers are offered.
Discovering the reason does not mean you have to adopt the reason. It is the mark of an educated mind to be able to entertain a thought without accepting it. Aristotle
Christian anti-Judaism, and a plot to steal Jewish proptery. The only exception is Spain, where the above was true, but Jews were treated the same as Muslims. Spain was to be Catholic only. Jews were viewed as collaborators with the Muslims.
