Abstract/Summary

This article proposes a new theoretical framework based on conflict escalation theory and the concept of critical junctures to facilitate a more transparent analysis of the war in Ukraine’s Donbas. It argues that researchers have proposed a variety of causes of the outbreak of violence in the region. However, in the absence of an overarching theoretical framework, it remains difficult to analyse the interplay of these causes and compare their explanatory power. In response, this article develops a theory-guided escalation sequence model. According to this model, the conflict’s formative phase consisted of an escalation sequence that lasted from April until August 2014 and comprised six critical junctures. This article argues that attempts to explain the conflict should be evaluated and compared in terms of their ability to explain these critical junctures. It concludes that similar escalation sequence models could improve research on armed conflict beyond the case of the Donbas.
