Theories of Secession [PDF ebook] 

Theories of Secession presents a systematic analysis of the recent rise of secessionist movements in global politics. Bringing together some of the most respected scholars in their field, this study locates the right to secede in the context of contemporary political theory. The chapters deal with problems of nationalism and federalism, special rights to secede, conditions of ethnic and cultural pluralism and asks if constitutions should include a right to secede.
