Rome warred, and split into three.
War, many emperors, many assassinations.
Sacked by Goths and Vandals, and Juthungi.
Then, that great Persecutor Diocletian
United the Kingdom, and then divided it
Between East and West.
And then Constantine took control
Of all, and issued the Edict of Milan
Making Christianity Legal,
And commissioned the council of Nicea.
