The year is 732. The Muslims have just defeated the Franks at the Battle of Tours and are continuing to expand. A third siege of Constantinople has been successful and the Muslims have conquered the Byzantine Empire. The Muslims conquered both Rûm and Ruma. Christianity was wiped off of the face of the Earth. Subsequent conversions of Slavs led to an Islamic Europe. Eventually, almost every trading partner of the Arabs converted to Islam. However, Islam in Europe, South, and Southeast Asia became ijtihadi, or secular, Muslims.
