This article focuses on unilateral sovereignty referendums pursued by territorial autonomies. Due to their unilateral character, such referendums are unlikely to gain external recognition and, as a result, fail to effect or prevent any de jure change in sovereignty. However, they are still pursued despite these constraints, suggesting that they serve purposes other than formal changes in sovereignty. To explain this phenomenon, the article proposes a framework of seven potential motivations. The framework is examined through the case of Gagauzia’s 2014 referendums, which addressed two key issues: Moldova’s foreign alignment and Gagauzia’s deferred independence. The analysis follows three referendum stages — proposal, initiation, and implementation — focusing on the dual leadership of the executive and legislative branches. Drawing primarily on newspapers affiliated with these branches, the study finds empirical support for three key motivations: advancing the individual and collective political interests of autonomy leadership, strengthening Gagauzia’s ties with its patron (Russia), and empowering the territorial autonomy vis-à-vis the parent state (Moldova). This article contributes a framework of motivations for unilateral sovereignty referendums tailored specifically to territorial autonomies, going beyond existing explanations developed for all polities. It also provides a detailed account of one of the most significant political events in Gagauzia’s history.
