Final answer:
Christian communities in the Middle East and North Africa from 650 to 1300 were thriving communities connected by inter-regional trade, especially participating in trades like the silk trade. They were generally considered dhimmis and retained their religious identity amidst Islamic cultural adoption, and while at times faced persecution, they often lived within a framework of approximate toleration.
Step-by-step explanation:
Christian communities in the Middle East and North Africa from 650 to 1300 can be described as thriving communities connected by inter-regional trade. Despite being under pressure from the expansion of Islamic power, many Christians, termed as 'Mozarabs', adopted aspects of Islamic culture. Moreover, they were actively involved in trade, as seen with the Armenian Christians in the silk trade, and they lived in approximate tolerance with Muslims and Jews. Dhimmis, or protected non-Muslim minorities, which included Christians, were a part of the economic fabric of the Islamic empires, often being essential to commercial activities due to their specializations and contacts.
There were, however, instances of persecution and marginalization, and the potential for violence by the dominant group always existed. Yet, many Christian communities managed to flourish economically and maintain their religious identity despite periods of adversity.
