From the war on terror to the global financial crisis, traditional concepts of world politics are being challenged on a daily basis. In these uncertain times, the study of international relations and the forces that shape them have never been more important. Written specifically for students who are approaching this subject for the first time, World Politics is the most accessible, coherent and up-to-date account of the field available. It covers the historical backdrop to today's political situations, the complex interactions of states and non-state actors, the role of political economy, human security in all its forms, and the ways in which culture, religion and identity influence events. World Politics takes a new approach that challenges traditional interpretations, and will equip students with the knowledge and the confidence needed to tackle the big issues.
