This fourth edition of Politics in the Developing World, just like the previous editions, has benefited substantially from feedback by referees and readers. The editors wish to thank all those who offered comments and also Oxford University Press for its decision to commission a fourth edition. We would also like to thank Vegard Vibe, University of Bergen, for excellent research assistance throughout this fourth edition of Politics in the Developing World, as well as for help with the online resources. Thanks are also due to Ane Thea Djuve Galaasen for research assistance on Chapter II. On a sadder note, we must relate that Adrian Leftwich died while we were assembling this edition; he has been an outstanding scholar in the field, as well as a key contributor to this volume, and will be greatly missed.
