WORLD HISTORY

Detailed explanation-1: -Christianity was a major unifying factor between Eastern and Western Europe before the Arab conquests, but the conquest of North Africa sundered maritime connections between those areas. Increasingly the Byzantine Church differed in language, practices, and liturgy from the western Church.

Detailed explanation-2: -The Muslim conquerors eventually came into possession of various Greek and Roman manuscripts. Rather than destroy these works, Muslim scholars carefully preserved them, translating them into Arabic, studying them, and in some cases building on ideas set down by the ancient writers in their own works.
