The term vulnerability has become increasingly integral to humanitarian legislation, policies, discourse, and procedures in contexts of displacement. While people categorized as “vulnerable persons” are ostensibly entitled to specialized care, this categorization is widely used to divide people into those “legitimate” and “illegitimate” to receive basic rights and care. Critical feminist scholarship has highlighted how gender is the dominant lens through which vulnerability is constructed and recognized. This affects all people during displacement. However, here we address the implications of this framework for men’s experiences of displacement, exploring as a case study the issue of housing for displaced people in Greece. Drawing on our independent fieldwork and interviews with humanitarians and displaced men, we demonstrate how gendered conceptions of vulnerability are not only integrated into institutionalized immigration apparatuses but also circulate in the everyday discourses, practices, and affective economies that constitute the Greek care regime. The result is that a form of necropolitics is exercised against men, forcing them to reside in conditions of slow violence and permanent injury. We address the gendered nature of this necropolitics as well as the gender-specific consequences for men at Europe’s borders.
