Le Vie della conquista araba nell'Africa del nord

The research suggests a study of the viability of northern Africa in the phase of transition from Late Antiquity and Byzantine age, to Arab period. In 647 A.D. Byzacena suffers the first attack by muslim armies, and in 698 A.D., the annexation of Maghrib area to "dār al Islam" is completed. The study of the routes used by muslim armies, and the following changement of viability in Medieval age represent the starting point for a dyacronic analysis of evolution of communications from Roman age to first Medieval age. The introduction specifies the chronological phases: The Bizantine age, from the conquest of Giustinianus, to exarchate and the second half of VII century A.D. The study of the evolution of communication routes in Roman age is the key to specify continuities and differences concerning viability in Medieval age (in particular until XI century A.D.). Literary and epigraphic sources, especially arabic sources, represent the main support of the research. The main subject of the research concerns different aspects on viability from major routes to frontier ways. In particular southern routes, used before for defence and control of Roman Empire, in VII century are used as means for diffusion of Islam and way of military operations in the West (Maghrib). Continuity with Roman route system and its evolution refered to new islamic capitals, together with gradual movement toward south Africa, constitutes the result and the synthesis of transition between the two systems.
