During the 5th to 9th century, Coptic culture was influenced by Byzantium and Early Orthodox culture, which were the most powerful in Europe and the Mediterranean until the mid 15th century. There is much evidence from literature, architecture, clothing, and religious art which indicates this cultural connection. In addition, we can see from their ceremonies, their trade relations, and lifestyle, that the Coptic culture was very influenced by these two powerful cultures. In about the 8th century, an Arabic invasion resulted in the destruction of Coptic communities.
