Spanish enclaves). Mauretania Caesariensis was named after its capital Caesarea (now Cherchell); and comprised western and central Algeria. Mauretania gave the empire one emperor, the equestrian Macrinus. He seized power after the assassination of Caracalla in 217 but was himself defeated and executed by Elagabalus the next year. Emperor Diocletian's Tetrarchy reform (293) further divided the area into three provinces, as the small, easternmost region of Sitifensis was split off from Mauretania Caesariensis. The Notitia Dignitatum (c. 400) mentions themas still existing, two being under the authority of the Vicarius of the diocese of Africa: A Dux et praeses provinciae Mauritaniae et Caesariensis, i.e. a Roman governor of the rank of Vir spectabilis, who also held the high military command of dux, as the superior of eight border garrison commanders, each styled Praepositus limitis ..., followed by (genitive forms) Columnatensis, Vidensis, inferioris (i.e. lower border), Fortensis, Muticitani, Audiensis, Caputcellensis and Augustensis. A (civilian) Praeses in the province of Mauretania Sitifensis. And, under the authority of the Vicarius of the diocese of Hispaniae: Late Antiquity Roman-Moorish kingdoms During the crisis of the 3rd century, parts of Mauretania were reconquered by Berber tribes. Direct Roman rule became confined to a few coastal cities (such as Septem in Mauretania Tingitana and Cherchell in Mauretania Caesariensis) by the late 3rd century. Historical sources about inland areas are sparse, but these were apparently controlled by local Berber rulers who, however, maintained a degree of Roman culture, including the local cities, and usually nominally acknowledged the suzerainty of the Roman Emperors. In an inscription from Altava in western Algeria, one of these rulers, Masuna, described himself as rex gentium Maurorum et Romanorum (king of the Roman and Moorish peoples). Altava was later the capital of another ruler, Garmul or Garmules, who resisted Byzantine rule in Africa but was finally defeated in 578. The Byzantine historian Procopius also mentions another independent ruler, Mastigas, who controlled most of Mauretania Caesariensis in the 530s. In the 7th century there were eight Romano-Moorish kingdoms: Altava, Ouarsenis, Hodna, Aures, Nemenchas, Capsa, Dorsale and Cabaon. The last resistance against the Arab invasion was sustained in the second half of the 7th century mainly by the Roman-Moorish kingdoms -with the last Byzantine troops in the region- under the leadership of the Christian king of Altava Caecilius, but later ended in complete defeat in 703 AD (when the queen Kahina died in battle).
