As fellow People of the Book, early Islam was very tolerant of them. Life under the caliph was pretty good for most jews and christians. The city of Jerusalem fell after a siege of six months.
Under command of Muhammad’s official successor, the caliph, they overran the Byzantine (or Eastern Roman) provinces here.
ĭuring its stellar ascent in the 7th century CE, Islamic forces conquered the medieval Orient – i.e., the Asian and African coastlines of the Mediterrean Sea. Muhammad’s teachings led to a great Islamic empire in the Orient.
