This paper presents one of the early outcomes of the NOMOS project, focusing on inheritance law within the Syriac legal traditions. In Syriac Christianity, from the sixth to the eleventh century and beyond, inheritance law constituted one of the two principal areas of concern for jurist-bishops, alongside family law. In the patriarchal culture of the late antique Near East, including Syriac Christianity, legal norms of inheritance and succession served two closely related domestic aims: the transmission of household property to the next generation and the perpetuation of the household head's name, that is, family identity, through offspring. In a period marked by intense intellectual exchange, religious competition, and conversion, these domestic aims assumed broader communal significance. Inheritance law became a mechanism for retaining property within the community and preserving a distinct communal identity across generations. Given the strongly patriarchal framework, this continuity was largely dependent on male lineage; any disruption therefore generated legal and social tension. Three recurrent scenarios in particular provoked such crises: the death of a household head without sons, the conversion of a potential heir to another religion (mainly Zoroastrianism and then Islam), and disputes over a widow's inheritance rights. Against this background, the paper examines the formation of inheritance law in the Syriac legal traditions through an analysis of how Syriac authors responded to these situations in dialogue with Zoroastrian and Islamic legal systems. It draws on selected passages from the Syriac legal corpus, ranging from Simeon of Rewardashir (c. 650) to Yoḥannan bar Abgare (d. 905). These texts, edited with the assistance of AI technology, are analyzed to trace how Syriac inheritance law(s) evolved from a rigid religious to quasi-civil rulings in response to shifting social relations, economic conditions, and religious contestations.
