jan 1, 700 - Introduction of Islam

Description:

During the 7th century AD the Muslim Arabs conquered Syria soon after the death of Muhammad, establishing a new regime to replace the Romans (or Byzantines as the Eastern Romans are sometimes called). Though Islam and the Arabic language were officially dominant under this new regime, the general populace still took time to convert from Christianity and the Syriac language.
