Mauretania Caesariensis in the context of "Hinterland"

Mauretania (/ˌmɒrɪˈteɪniə, ˌmɔːrɪ-/; Classical Latin: [mau̯.reːˈt̪aː.ni.a]) is the Latin name for a region in the ancient Maghreb. It extended from central present-day Algeria to the Atlantic, encompassing northern present-day Morocco, and from the Mediterranean in the north to the Atlas Mountains. Its native inhabitants, of Berber ancestry, were known to the Romans as the Mauri and the Masaesyli.

In 25 BC, the kings of Mauretania became Roman vassals until about 44 AD, when the area was annexed to Rome and divided into two provinces: Mauretania Tingitana and Mauretania Caesariensis. Christianity spread there from the 3rd century onwards. After the Muslim Arabs subdued the region in the 7th century, Islam became the dominant religion.

The Vandal Kingdom (Latin: Regnum Vandalum) or Kingdom of the Vandals and Alans (Latin: Regnum Vandalorum et Alanorum) was a confederation of Vandals and Alans, which was a barbarian kingdom established under Gaiseric, a Vandalic warlord. It ruled parts of North Africa and the Mediterranean for 99 years from 435 to 534 AD.

In 429 AD, the Vandals, estimated to number 80,000 people, had crossed by boat from Hispania to North Africa. They advanced eastward, conquering the coastal regions of what is now Tunisia, and Algeria. In 435, the Western Roman Empire, then ruling North Africa, allowed the Vandals to settle in the provinces of Numidia and Mauretania when it became clear that the Vandal army could not be defeated by Roman military forces. In 439, the Vandals renewed their advance eastward and captured Carthage, the most important city of North Africa. The fledgling kingdom then conquered the Roman-ruled islands of Mallorca, Sicily, Sardinia, and Corsica in the western Mediterranean. In the 460s, the Romans launched two unsuccessful military expeditions by sea in an attempt to overthrow the Vandals and reclaim North Africa. The conquest of North Africa by the Vandals was a blow to the beleaguered Western Roman Empire, as North Africa was a major source of revenue and a supplier of grain (mostly wheat) to the city of Rome.

Marcus Opellius Macrinus (/məˈkrɪnəs/; c. 165 – June 218) was a Roman emperor who reigned from April 217 to June 218, jointly with his young son Diadumenianus. Born in Caesarea (now called Cherchell, in modern Algeria), in the Roman province of Mauretania Caesariensis to an equestrian family of Berber origins, he became the first emperor who did not hail from the senatorial class and also the first emperor who never visited Rome during his reign. Before becoming emperor, Macrinus served under Emperor Caracalla as a praetorian prefect and dealt with Rome's civil affairs. He later conspired against Caracalla and had him murdered in a bid to protect his own life and succeeded Caracalla as emperor.

Macrinus was proclaimed emperor of Rome by 11 April 217 while in the eastern provinces of the empire and was subsequently confirmed as such by the Senate; however, for the duration of his reign, he never had the opportunity to return to Rome. His predecessor's policies had left Rome's coffers empty and the empire at war with several kingdoms, including Parthia, Armenia, and Dacia. As emperor, Macrinus first attempted to enact reform to restore economic and diplomatic stability in Rome. While Macrinus' diplomatic actions brought about peace with each of the individual kingdoms, the additional monetary costs and subsequent fiscal reforms generated unrest in the Roman military.

Siga was a Berber and Roman port located near what is now Aïn Témouchent, Algeria. Under the Roman Empire, it was part of western Mauretania Caesariensis, bordering Mauretania Tingitana.

Mauri (from which derives the English term "Moors") was the Latin designation for the Berber population of Mauretania, located in the west side of North Africa on the shores of the Mediterranean Sea, Mauretania Tingitana and Mauretania Caesariensis, in the North of present-day Morocco and north western Algeria.

The Kingdom of Altava was an independent Christian Berber kingdom centered on the city of Altava in present-day northern Algeria. The Kingdom of Altava was a successor state of the previous Mauro-Roman Kingdom which had controlled much of the ancient Roman province of Mauretania Caesariensis. During the reign of Kusaila, it extended from Volubilis in the west to the Aurès and later Kairaouan and the interior of Ifriqiya in the east. This Kingdom collapsed following Eastern Roman military campaigns to decrease its influence and power after Garmul invaded the Exarchate of Africa.

The collapse of the Mauro-Roman Kingdom lead to the rise of several petty berber kingdoms in the region, including the Kingdom of Altava, which was centered on the capital of the older kingdom. The kingdom continued to exist in the Maghreb until the conquest of the region by the Umayyad Caliphate in the seventh and eighth centuries.

Caesarea in Mauretania (Latin: Caesarea Mauretaniae, meaning "Caesarea of Mauretania") was a Roman colony in Roman-Berber North Africa. It was the capital of Mauretania Caesariensis and is now called Cherchell, in modern Algeria.

In the present time Caesarea is used as a titular see for Catholic and Eastern Orthodox bishops.
