Middle Ages [SEP] Rise of Islam
Religious beliefs in the Eastern Roman Empire and Iran were in flux during the late sixth and early seventh centuries. Judaism was an active proselytising faith, and at least one Arab political leader converted to it. Christianity had active missions competing with the Persians' Zoroastrianism in seeking converts, especially among residents of the Arabian Peninsula. All these strands came together with the emergence of Islam in Arabia during the lifetime of Muhammad (d. 632). After his death, Islamic forces conquered much of the Eastern Roman Empire and Persia, starting with Syria in 634–635, continuing with Persia between 637 and 642, reaching Egypt in 640–641, North Africa in the later seventh century, and the Iberian Peninsula in 711.
