Abstract
This chapter argues that the principle of nationality offers a perspective on the secession issue that avoids condoning a secessionist free‐for‐all without forcing us to defend existing state boundaries regardless. It suggests the need for a contextual approach to secession, examining the extent to which different groups have or have not evolved separate national identities, how minorities are likely to fare under various possible regimes, and whether partial autonomy regimes might be more justified than secession.
