The Great Constantine was the first Christian emperor of the Roman Empire. His mother, Helena, set a great example for him, and they remained close even during Helena's exile. Constantine allowed freedom of religion within the empire and was eventually baptized. He was a great warrior and tried diligently to please his mother. The convening of the bishops at Nicaea, the new creed, and the enforcement of orthodox religion resulted in many of the Christian documents used in Northern Africa to be buried. The discovery of these documents has allowed many to become aware of the great differences that existed within the church during the fourth century. Years after Constantine's death the Christian Religion became the only religion allowed with the Roman Empire and a new set of problems surfaced.
