paragraph_text: Byzantine Empire (Eastern Roman Empire)
  
  The Eastern Roman Empire, today commonly known as the Byzantine Empire, ruling from the Balkans to the Euphrates, became increasingly defined by and dogmatic about Christianity, gradually creating religious rifts between the doctrines dictated by the establishment in Constantinople and believers in many parts of the Middle East. By this time, Greek had become the ' lingua franca ' of the region, although ethnicities such as the Syriacs and the Hebrew continued to exist. Under Byzantine/Greek rule the area of the Levant met an era of stability and prosperity.
