The Egyptian Christians are called Copts, a word .
derived from the Greek word for the country, Aegyptos. The new religion quickly spread .
from Alexandria into the hinterland, reaching Upper Egypt by the 2nd century. .

"His life as a merchant in Mecca and on the caravan routes exposed Muhammad to the .
world beyond Arabia and probably made him acutely aware of the clan rivalries that had .
