Jews were eventually welcomed in Poland, whose king declared the Statute of Kalisz to protect them. For example, Christians could not testify against Jews for committing crimes, which commonly had led to unjust accusations and punishments. For many Christians, however, this protection increased their resistance. Many Jews, so-called "Ashkenazim", gathered in Eastern Europe because of this, however. In Spainand Portugal under Muslim rule, the so-called Al Andalus period, Jews were generally accepted although they could not take part in the government. After Christian rule was re-established on the Iberian peninsula, Jews were rejected and persecuted if they stayed. Some sought refuge in the Ottoman Empire, which was then relatively tolerant to Jews and Christians and allowed them to have their own courts and laws, as long as they payed taxes and did not resist Ottoman rule.
