The Commonwealth consists of only a quarter of the world's states and yet the Commonwealth Secretariat and Foundation have made and continue to make a significant contribution to global politics. This book provides the most up-to-date and comprehensive overview of this key international institution. The book: explains the history, structure and future of the Commonwealth; demonstrates the central role that the Commonwealth has played in advancing decolonization and supporting multiculturalism, democracy and human rights; details the significant links between Commonwealth institutions and myriad networks concerned with, education, development, gender, health, islands, literature, media and sport; examines the Commonwealth within the context of wider debates about 'global' governance and globalization. "Commonwealth" is a superb examination of an often neglected but crucial force in world affairs. It will be of considerable interest to students of international organizations, international relations, development and North-South relations.
