The fifth edition of this bestselling textbook offers a comprehensive and engaging introduction to International relations and has been fully updated to cover the dramatic changes in recent world politics. Written in the author?s unique and engaging style, the text explores everything from foreign policy and security to global governance and the global economy, to show how the theories and concepts Brown outlines are the only way to make sense of contemporary issues and events. With reference to such diverse events as Brexit, the Russian armed conflict in Ukraine, the financial crisis, the rise of China, and the challenges of identity politics, the author expertly shows how the range of theories presented in the book allow for an understanding of the destabilising events and developments that characterise global politics today, and will continue to do so in the future.
