Mbembe names necropolitics as the organisation of sovereignty through the power to expose populations to death, injury and uninhabitable life. The essay extends biopolitical analysis by insisting that colonial occupation, racialisation, slavery and contemporary warfare cannot be understood solely through the administration of life. Its conceptual operation is spatial: plantations, colonies, occupied territories and camps are analysed as infrastructures in which legal order, territorial fragmentation and lethal force converge. Methodologically, Mbembe combines political philosophy with colonial history to reveal how exceptional violence becomes ordinary governance. The work’s wider bridge reaches urbanism, border studies and environmental justice because the distribution of vulnerability is always materialised through walls, checkpoints, extraction zones and differentiated access to mobility, care and security. Necropolitics therefore identifies death not as the failure of political systems but as a condition actively designed into them, exposing the spatial and institutional mechanisms by which some lives are protected while others are rendered disposable.
