This article challenges the well-established presentation within conflict studies of paramilitary organizations as state-manipulated death squads or self-defence groups, and argues that some present-day militias extend their functions well beyond the role of shadowy pro-regime enforcers. Drawing its empirical insights from Ukrainian pro-government volunteer battalions and supporting its findings with empirical observations from other parts of the world, the article posits that the rise of powerful militia organizations acting in parallel with the state makes it imperative to revisit the theory and typology of paramilitary violence. The key theoretical argument of the article is that ‘state-parallel’ militias differ qualitatively from the ‘state-manipulated’ paramilitaries that are typical of the Cold War period. The article shows that although ‘state-parallel’ paramilitaries are not a new phenomenon, they have thus far remained critically understudied and undertheorized.
