Stories of fallen Kurdish revolutionaries who return to the living in dreams, and of Druze souls who circulate across securitized borders gesture at forms of vitality and animation that persist beyond biological death. In this article, we have put forward the concept of “insurgent immortality” to make sense of the political potency of revolutionary martyrs and past lives among Kurdish communities from Turkey and Syrian Druze communities in the Israeli-occupied Golan Heights. By insisting on the immortality of their dead, we argue, these stateless communities articulate a claim to counter-sovereignty. What makes these communities’ practices aimed at mastering and transcending death different from the sovereignty claimed by nation-states is that apparitions of dead martyrs and past lives work as expansive, boundary-crossing mechanisms, rather than the territorializing logics of enclosure and containment that mark state sovereignty. The immortality we describe in this article is insurgent because it relies on the recognition and cultivation of long-term exchange relations between the living and the dead, through which debt becomes a modality of generative expansion across both this and otherworldly times and spaces. The resulting sense of generalized indebtedness opens up spaces of liminality in which the dead come alive as both inspiring and unsettling figures. We develop insurgent immortality as a comparative concept that emerges from the specific ethnography of each case yet reaches across their contextual boundedness. In this way, we hope to inspire renewed conversation about shared trajectories of resistance, including its ambivalences, that arise in contexts of statelessness, occupation, and disenfranchisement.
