Abstract

The proposition that security threats can drive states to pool their sovereignty has been around for some time. The existence of these threats, according to William Riker, is a necessary condition for political unification. A less common argument centers on linguistic homogeneity; it asserts that states must be sufficiently similar and speak the same language before they can successfully imagine a common state. This paper tests both hypotheses in a large-N analysis that identifies all instances of voluntary political unification between 1816 and 2001. It takes the form of a falsification probe and examines whether any unification happened in the absence of either an external security threat or a common language. It finds that political unification has occurred in relatively tranquil settings, but that all unifying dyads have shared a common language. Security threats are not a necessary condition, but a common language may well be. Adapted from the source document.
