Jews were forbidden from becoming tax or toll farmers. According to customary practice, anyone could have bought these rights in a specific area for an agreed upon sum to be paid to the king. Despite this ruling, Jews often found this to be one of the few economic possibilities opened to them. This in turn caused resentment from both the local population and Christian tax farmers who saw them as competition. In general, its goal was to cut off contact as much as possible between Christians and Jews both socially and physically (ghetto).
