The Abbasid Caliphs
The Abbasid Caliphs were the dynastic rulers of the Islamic world between the middle of the eighth and the tenth centuries. They headed a Muslim empire that extended from Tunisia through Egypt, Syria, Arabia, and Persia to Uzbekistan and the frontiers of India. But unlike previous conquerors, the Abbasid Caliphs presided over a multicultural empire where conversion was a relatively peaceful business.
