Abstract
The paradox of federalism is about whether self-rule accommodates or exacerbates ethnic divisions. A federal arrangement that formally recognizes ethno-linguistic diversity to help manage divisions can also pave the way for eventual disintegration. In this introductory piece, the editors of this Special Issue highlight a number of common reference points for the study of the secession-inducing and secession-preventing features of federalism: First, the political will of the secessionists and their capacity to mobilize to this end; secondly, the characteristics of federal institutional/constitutional design; and, thirdly, economic and sociological uncodified factors that have a bearing upon these questions.
