HistoryEdit

The Roman Empire was initially divided into 46 provinces, which were subdivided by Diocletian around 300 AD into 101 provinces, which in turn were grouped into 12 dioceses. At the division of the Empire in 395, the structure was changed into four prefectures, 15 dioceses and 119 provinces. With the conquest of Hispania by the Vandals, Alans, and Suebi in 409 the diocese began to collapse.
