Patriarcat, califat et réseaux : le moment Ḥarrān au cœur de l’Empire (126/744-140/758)

Abstract

Abstract This paper offers a cross-analysis of Syriac and Arabic sources related to the Jazīra, the northern province of the caliphate, during the second/eighth century. Specifically, it delves into what the author refers to as the “Ḥarrān moment”. It pertains to the period when this regional town was turned to the last capital of the Umayyads, and immediately to the centre of the provincial government of the future caliph al-Manṣūr, prior to his ascent to power in 754-755 CE. The study views the Abbasid revolution as part of a single decade of civil war (fitna) (744-755) and emphasises the continuity between two dynasties, challenging the traditional historiographical divide of the “Abbasid revolution.” The “Ḥarrān moment” marked a significant shift in central political (and ecclesiastical) power from Umayyad Damascus to Abbasid Baghdad. Syriac sources underscore the centrality of the Jazīra and its capital, as well as the similarities in the political and military history before and after 132/750. Moreover, local ecclesiastical chronicles highlight how Ḥarrān became the centre of the Church at that time, partly by chance and partly due to geopolitical and geo-ecclesiological co-construction. It is argued that this results from a period when prelates and patriarchs became more courtiers, and both Marwān II and al-Manṣūr initiated a policy of affiliation of the Syrian Orthodox Church to the Caliphate, particularly through the issuance of diplomas (sigillions). This article demonstrates that the physical encounter of these two central powers, civil and ecclesiastical, in this strategic location during this critical time of interconnected political-military and ecclesiological turmoil and changes of the 740s-750s, is the key to understanding this process. The study specifically examines the similarities between monastic and tribal provincial and infra-provincial networks, which arise from the same political constraints, to explore the formation and crystallisation of parallel regional ecclesiastical and political blocks during the mid-eighth century CE.
