In the year 250/864–65, Baghdad’s governor Muḥammad b. ʿAbd Allāh b. Ṭāhir ordered the defilement of a prisoner’s corpse and grave site. The prisoner, Isḥāq b. Jināḥ, had been a criminal magistrate serving the rebel leader Yaḥyā b. ʿUmar, who had led a failed revolt in Kufa against the Abbasid caliphate (132–650/750–1258). According to the fourth/tenth-century historian al-Iṣbahānī, the governor demanded that the deceased Isḥāq b. Jināh not receive a funerary prayer, corpse-washing, or a burial shroud. Moreover, he ordered the corpse to be immersed in water in a grave and buried at a Jewish ruin. The governor’s intentional neglect of proper Islamic funerary rituals is shocking but not entirely surprising. Medieval Islamic political chronicles, biographical dictionaries, and social commentaries abound with darkly salacious reports of corpse neglect and even violence, shining a light on the efforts of the living to affect the dead. Why would anyone seek to “harm” a corpse? And what purpose did medieval Islamic historical narratives of necroaggression serve? This article addresses the narrative power of corpse violence in Greater Iraq during the mid-third/ninth and early fourth/tenth centuries, investigating the political meanings inscribed on bodies unmade by others. Viewing necroaggression as a type of performative political act, the article examines a vibrant polemical discourse that toyed with administrative concerns over coercion as well as popular anxieties over possible sensations experienced postmortem.
