As a historical figure, little is known about Count Julian. The earliest extant source describing Julian is
Ibn 'Abd al-Hakam's 9th-century
Kitāb futuḥ misr wa akhbārihā (
The History of the Conquests of Egypt, North Africa, and Spain), which claims that Julian first resisted the
Muslim conquest of the Maghreb, and then joined the
Umayyad conquest of Hispania. Other details, such as the existence of a daughter known as
La Cava, appear in the 11th century. The debate concerning Julian's historicity ranges at least to the 19th century; by the 21st century, the academic consensus seemed to lean toward Julian being ahistorical, with most scholars since the 1980s agreeing with Roger Collins that the portions of the story concerning Florinda la Cava are fantastical and that arguments for even Julian's existence are weak, while not entirely excluding the possibility that he was a real personage.
Byzantine and native resistance and the importance of Ceuta Byzantine strategy at the time, as articulated by
John Troglita, a Byzantine general under
Justinian I, advocated dispersal and retreat back to artificially or naturally fortified places and ambush tactics against a superior foe. The Exarchate of Africa was divided into ducates led by a duke (, ), also called
strategos (στρατηγός).
Disintegration and Mauretanisation of the Byzantine exarchate The Arab conquest of North Africa was quite rapid. The Umayyads faced an internally weakened Byzantine state, one of whose emperors,
Constans II, was assassinated in his bath in the midst of an army revolt and another,
Justinian II, who had been deposed, mutilated and exiled in 695, only a few years before the Arabs broke through into the province of Africa in 697. For a while, a Byzantine expeditionary force under
John the Patrician was able to re-supply coastal garrisons and in some cases aid in the reconquest of lost territory, especially the important city of
Carthage, but the next year the Arabs sent in their own reinforcements after an appeal to the caliph by
Hasan ibn al-Nu'man, and forced the Byzantines to yield most of the province. After losing the subsequent
Battle of Carthage outside the walls, the expeditionary force retreated to its island naval bases to re-group, whereupon the
Droungarios of the
Cibyrrhaeot Theme, Apsimar, seized control of the fleet's remnants after a
mutiny by naval officers. The emperor
Leontius was himself deposed and mutilated, to be replaced by Apsimar, now calling himself
Tiberius III.
Identification of "Julian" The earliest extant source for Julian is a chapter in
Ibn 'Abd al-Hakam's work
Futuḥ misr headed
Dhikr Fatḥ Al-Andalus (
Chapter on the Conquest of Spain). Its 19th-century translator into English, John Harris Jones, noted that Julian is usually called يليان (
Ilyan) by later Arabic authors, while in the manuscripts available to Jones he is called بليان (
Bilian). A better manuscript with vowels was available to
Torrey, who in his critical edition of the Arabic text, gave the least corrupt form as بؙلْيان (
Bulyan), which he supposed should be corrected to يُلْيان (
Yulyan). Jones disputes
Juan Francisco Masdeu and "most [contemporary] Spanish critics", who held that Julian was a fictional character, as well as
Pascual de Gayangos y Arce's assertion that no sources prior to the 11th century mention any quarrel with
Roderic on Julian's part; Jones replies that these only seem true if one consults Christian sources, and names both Ibn 'Abd al-Hakam and
Ibn al-Qūṭiyya as 9th-century historians who mention both Julian and his rift with Roderic. in in Indeed, historically
Ceuta (then called "Septem") and the surrounding territories were the last area of
Byzantine Africa to be occupied by the Arabs: around 708 AD, as Muslim armies approached the city, its Byzantine governor, Julian (described as "King of the Ghomara"), changed his allegiance and exhorted the Muslims to invade the
Iberian Peninsula. After Julian's death, the Arabs took direct control of the city, which the indigenous
Berber tribes resented. They destroyed Septem during the
Kharijite rebellion led by
Maysara al-Matghari in 740 AD, but Christian Berbers remained there (even if harshly persecuted in the next centuries). in ==Role in the conquest of Hispania==
