Social science scholars have repeatedly predicted the demise of regional (or peripheral) nationalism, from the late nineteenth century to the post-World War II period and in the 1990s. However, all suggestions about the death of regional nationalism have been proven wrong. On the contrary, nationalist movements in the West have not only survived advanced capitalist development in liberal democratic contexts but have thrived as well. In the developing world, decolonization gave rise to a variety of regional nationalist movements that frequently spiraled into violent conflict and secessionist attempts. To deal with regional nationalism, states often turned to devolution, resulting in the implementation of various schemes of autonomy, most of which came under the guise of federalism. Three trends characterize the literature on regional nationalism and its management through devolution: a change in the way regional nationalism is viewed; a transformation in the type of political, institutional, and constitutional response scholars have suggested toward regional nationalism; and a willingness to accept, or even favor, secession as a possible solution to conflict in multinational and/or multiethnic countries. At the same time, there are at least two challenges in the study of regional nationalism and its management: objectivity and the need to develop a greater comparative perspective.
