It is said they were very warlike, dishonest, and backstabbing, so they were difficult to control. Their king of the moment was trying to find a way to keep them subservient, so he considered forcing them into one of the authoritarian religions from the middle east. He considered Christianity and Judaism, and basically flipped a coin and chose Judaism.
This is supposed to be the origin of the "White Jews", known as the Ashkenazim.
Many dispute this.
