Available essays on Pashtunwali describe this system of customary laws and ethics for the most part as a static model of ideal conduct, without a diachronic perspective. Offering a historical approach to Pashtunwali, this article introduces and analyzes fragmentary data on the nənawāte custom from early modern Pashto sources—historiographical narratives of the Khatak chieftains in the Tarikh-i Murassaʿ (finished 1724) and the romantic poem Adam Khan aw Durkhaney (1706/7). Recorded cases of resorting to nənawāte, considered among the main pillars of Pashtunwali but still variously interpreted, prove that this is a complex legal custom based on the right to appeal for protection, mediation, and reconciliation. As a common means of dispute settlement, nənawāte originates with a binding request for help and favor in a conflict situation. The discussion of nənawāte is preceded by a brief overview of the existing scholarly definitions of Pashtunwali, underscoring its emic perception as an ethnic identity marker.
