QUES: Non-Muslim groups in the Umayyad Caliphate, which included Christians, Jews, Zoroastrians, and pagan Berbers, were called dhimmis. They were given a legally protected status as second-class citizens as long as they accepted and acknowledged the political supremacy of the ruling Muslims. They were allowed to have their own courts, and were given freedom of their religion within the empire.[citation needed] Although they could not hold the highest public offices in the empire, they had many bureaucratic positions within the government.
