The phenomenon of tribal alliances of Nomadic peoples against Roman expansion on the Saharan borders of the Maghreb. “Roman administrative border versus local socio-cultural extensions”
Abstract
This study examines a specific moment of nomadic resistance to Roman expansion on the edge of the North African desert, manifested by tribal coalitions aimed at eradicating Roman tactics of military and cultural subjugation. It focuses primarily on the desert regions of Proconsular Africa (Libya and Tunisia), Numidia, and Mauretania Caesariensis (Algeria), but from an unusual perspective: that of the vast tribal coalitions formed through large-scale and geographically dispersed uprisings among the region's most prominent groups, such as the Garamantes, Gaetuli, Musulami, and Moors.
The central question of this research is to examine the historical reality of these tribal alliances against Roman expansion on the desert frontiers and their repercussions on the Maghreb countries. This has raised the following questions: What were their causes, circumstances, and true contexts? What were their main results at the local level? How can we explain the success of these tribal alliances, even if temporary, despite their political rivalries? Can this success be attributed to the depth and entrenchment of the socio-cultural fabric and its integration within the Maghreb population?
This study adopts a descriptive historical approach to understand the reality of these alliances, complemented by an analytical approach that examines their context and evolution. It notably highlights the link between Roman administrative policy on the desert borders of the Maghreb and the peoples who opposed it. The aim was to geographically fragment the region along a north-south axis. This fragmentation was followed by a policy of Romanization aimed at cultural fragmentation for the purposes of economic exploitation. The study also examines the reaction of the local population (nomads), which manifested itself on the ground as military resistance evolving from isolated tribal revolts to broader tribal alliances encompassing various ethnic groups. Finally, the study offers a synthesis of the findings.
The study concludes with a set of findings that primarily highlight the success of tribal alliances among the inhabitants of the borderlands and their role in weakening Roman influence in the mid-3rd century. This led to a decline in Roman territorial control and forced a retreat northward. This situation was reflected in the military and security reforms of Emperor Diocletian. On the ground, this manifested itself in the deployment of a new, intensive, and fortified army, as well as in the incursion of nomadic tribes into the Tell Atlas region. Furthermore, the study noted the persistence of activity in centers abandoned by the Romans, indicating a return of the region to the socio-economic character inherited from the Romans. These developments prompted the Roman authorities to revise their military and social strategies in the region.
Key words: Tribal alliances – Nomadic Bedouins – the Maghreb – Roman occupation.
