Diocese of Hispania

314 CE – 409 CE (approx.) · capital Emerita Augusta

The late Roman administrative unit that grouped the provinces of Iberia and north-west Africa under a single vicar based at Mérida.

Origins

The diocese was created in Diocletian's reforms around 297 to 314, grouping the provinces of Baetica, Lusitania, Carthaginiensis, Gallaecia and Tarraconensis with Mauretania Tingitana across the Strait. The Balearica province was added around 369. It formed part of the Praetorian Prefecture of the Gauls.

Rule and society

A vicarius at Emerita Augusta oversaw the provincial governors, mainly in justice and taxation, while separate officers commanded the army. Hispania was largely peaceful in the 4th century, a land of rich villas and cities. Christianity grew strong, as the Council of Elvira shows, and the emperor Theodosius I came from Cauca in the north.

Decline and legacy

In 409 Vandals, Alans and Suebi crossed the Pyrenees during the usurpation of Constantine III and his general Gerontius. Rome partly restored control with Visigothic help, but the diocese effectively broke up as barbarian kingdoms took over.
