This book develops a systematic understanding of the conceptual, ethical, political and theoretical dimensions of intervention in an empirical/historical context. More specifically, the book aims to provide advanced undergraduate and postgraduate students with a systematic and critical understanding of ‘intervention/non-intervention’ through examination of the doctrine’s conceptual, theoretical and normative underpinnings; the theory and practice of intervention in different historical periods; and the notion of ‘intervention’ as a (problematic) mode of governance that raises important theoretical as well as practical issues given contemporary conditions of globalisation. The book will focus primarily on the theory and practice of intervention as pertaining to the nexus between democracy/democracies and international society, but will extend beyond this core focus as appropriate.
