Comparing Independence Referendums: Why Do Some States Accept Them while Others Do Not?

Abstract

ABSTRACT This article aims to explain why some central governments accept to hold independence referendums while others refuse to do so. For this purpose, this investigation assesses a series of seven hypotheses on 131 international cases of secession consultations from 1944 to 2021 extracted from an updated version of the Contested sovereignty dataset. The results of the logistic regression model identify four relevant variables. In the first place, the competition/proximity model and the time variable explain the support brought by central governments for the organisation of self-determination referendums. Additionally, the study shows that the quality of democracy influences the decision to allow minorities to hold independence consultations. Finally, and with a lower level of significance, it is also argued that periods of previous violence incite host state authorities to agree to hold self-determination referendums.
