Answer:
The Umayyad and Abbasid Dynasties were ruled by caliphs. In general, these Muslim leaders were tolerant toward Jewish and Christian peoples, who had to pay a special tax to continue to practice their religion.
Step-by-step explanation:
The Umayyad and Abbasid Dynasties were powerful caliphates that ruled expanded territories over the Middle East and North of Africa, who altogether ruled over 600 years.
These empires allowed military expansion and enrichment of knowledge in the Muslim world. At first, both empires allowed non-muslims to preserve their faith in exchange for being subject to taxation, which helped to increase numbers in terms of population, administration, and power.
