AD250: Christianity at the time of Decian Persecution

This map shows Christianity at the time of the first General Persecution, by the Emperor Decius. Note the increasing density of the Christian population in Syria and Western Asia Minor, as well as the spread of Christianity in the Western half of the empire.
Middle stage: AD250 - AD406
The maps between 250 and 406 show the increasing spread and density of Christianity throughout the territory of the Roman empire and eventually beyond it. They expand outwards to detail the increasingly large area within which Christianity is now present, including Mesopotamia, Armenia and Ethiopia (whose capital cities, Ctesiphon, Etchmiadzin and Axum, are marked on the final map), as well as a thin spread along the western coast of India.
