Thoroughly updated in its fifth edition, World Politics in a New Era is a comprehensive and thought-provoking text for introductory courses on world politics. Reflecting the changes that have occurred worldwide since the collapse of the Berlin Wall--including recent upheavals in the financial sphere--the book integrates coverage of the competing threads of globalization and fragmentation, examining how they tangle and weave through studies of global politics, economics, and culture. It provides a uniquely in-depth treatment of the field by introducing key contemporary issues with theory; supporting these issues with historical context; and giving students the analytical tools to apply the theories to current issues. The text is enhanced by numerous pedagogical features and a comprehensive supplement package.
