Born out of the merger of Ebb Magazine and Prometheus Journal, both post-2019 creations that spoke to distinct but overlapping strains of revolutionary politics, Prometheus Magazine will be a regular physical magazine and online publication that draws on Marxist traditions that have been enriched by Black Radicalism, (Trans-)Feminism, Eco-Socialism, Abolitionist politics, and the theorisations of class consciousness and cultural hegemony to offer a revolutionary publication that facilitates strategic and programmatic development through analysis, critical reportage, and comradely debate. As a combined project, Prometheus Magazine embraces the premise that the revolutionary party has and continues to represent the most important – though not the sole – institution of the revolutionary movement. Since the epochal socialist defeats of the 1980s, the left in Britain has tried and failed again and again to cohere a political subject into a significant and unified entity. Now, the fractured afterlives of Corbynism have produced a new set of tendencies among the British left that we must engage and address.
