Mauretania Caesariensis


Mauretania Caesariensis was a Roman province located in what is now Algeria in the Maghreb. The full name refers to its capital Caesarea Mauretaniae.
The province had been part of the Kingdom of Mauretania and named for the Mauri people who lived there. Formerly an independent kingdom, and later a client state of Rome, it was annexed into the Empire formally during the reign of Claudius and divided into two provinces about 42 AD. A third province, named Mauretania Sitifensis, was later split off from the eastern portion during the reign of Diocletian in 293 AD. During and after the Fall of the Western Roman Empire in the 5th century, most of the hinterland area was lost, first to the Vandal Kingdom and later to the Mauro-Roman Kingdom, with Roman administration limited to the capital of Caesarea. The land was reconquered by Rome during the reign of Justinian. In the late 580s, under the emperor Maurice, all of the Maghreb was granted to the Exarchate of Africa, and Mauretania Caesariensis became part of a new province, Mauretania Prima. The Muslim conquest of the Maghreb brought an end to Roman rule in Mauretania, which became ruled by the Umayyad Caliphate as part of Medieval Muslim Algeria.

History

In the middle of 1st century AD, Roman emperor Claudius divided the westernmost Roman province in Africa, named Mauretania, into Mauretania Caesariensis and Mauretania Tingitana.
Mauretania Caesariensis included eight colonies founded by the Emperor Augustus : Cartennas, Gunugu, Igilgili, Rusguniae, Rusazu, Saldae, Zuccabar, Tubusuctu; two by the Emperor Claudius: Caesarea formerly the capital of Juba, who gave it this name in honour of his patron Augustus, and Oppidum Novum; one by the Emperor Nerva: Setifis; and in later times, Arsenaria, Bida, Siga, Aquae Calidae, Quiza Xenitana, Rusucurru, Auzia, Gilva, Icosium and Tipasa in all 21 well-known colonies, besides several municipia and oppida Latina.
Under Diocletian's Tetrarchy reform, the easternmost part was broken off from Mauretania Caesariensis as a separate small province, Mauretania Sitifensis, called after its inland capital Sitifis with a significant port at Saldae.
At the time of Diocletian and Constantine the Great, both Sitifensis and Caesariensis were assigned to the administrative Diocese of Africa, in the praetorian prefecture of Italy, while Tingitana was an outpost of the Diocese of Spain.
After the fall of the Western part of the Roman Empire, a Germanic Vandal Kingdom was founded, but the remaining Eastern Empire recaptured the area around 533, but most of Mauretania Caesariensis remained under the control of local Moorish rulers such as Mastigas, and it was not until the 560s and 570s that Byzantine control was established in the interior.
During the reign of Maurice, the empire was reorganized and a number of Exarchates were founded, among them the Exarchate of Africa which included Mauretania, among other territories. Mauretania Sitifensis was re-merged back into this province, and was granted the name "Mauretania Prima".
The Muslim conquest of the Maghreb for the caliphate under the Umayyad dynasty meant the end of the Byzantine Exarchate of Africa and Late Antique Roman culture there and Mauretania Caesariensis became part of the westernmost Islamic province called Maghreb.

Economy

The principal exports from Caesariensis were purple dyes and valuable woods; and the Amazigh or Mauri were highly regarded by the Romans as soldiers, especially light cavalry. They produced one of Trajan's best generals, Lusius Quietus, and the emperor Macrinus.

Religion

Caesarea was a major center of Judaism before 330, and Sitifis was one of the centres of the soldier cult of Mithraic mysteries. Christianity spread throughout in the 4th and 5th centuries.
Among the ruling class, Trinitarian Christianity was replaced by Arianism under the Germanic kingdom of the Vandals, which was established in 430, when the Vandals crossed the Strait of Gibraltar.
