I also wonder why, throughout the past thousand years why so many countrys have banished jews from their land. Edward I and edward III banished them from england as did spain and france at that time.
Even Ben Franklin wanted them denied entry into the US 200 some years ago.
could it be just pure racism, or maybe something more?
Quite simple. Jews denied and deny that the Roman emperor was a god, Jesus is their savior & that Muhammad is the last & greatest prophet...
If you look at how Christians & Muslims treated & treat eachother, you'll only see 1 difference, namely that Muslims & Christians are capable of defending themselves, whereas Jews weren't before they got their own nation.
Jews were a scattered people who had to settle amongst others who did not share their religion and culture. Since they were a minority & since they weren't part of the larger group, they soon became outcasts.
Add to that that Christianity has always frowned upon profit (except when in concerns the church) and that profit isn't something to look down upon in Judaïsm, plus the fact that Jews couldn't become members of the guilds or work for most Christian companies, Jews had to do that which Christians could not. Banking is a nice example.
They became rich, while Christians didn't. This alone is enough to cause resentment.
Besides, the Catholics weren't very tolerant towards anything or anyone who dared to think differently. Just think of the Cathars, Northern Crusades and Reformists.
