This course examines the international history of the post-9/11 September era. Almost two decades have elapsed since the 11 September 2001 terrorist attacks on the United States. In the aftermath of these events, the world has entered a period characterised by a number of distinct dynamics which have persisted and have significantly impacted the configuration of the global order. What is the nature of these changes, notably the militarisation of international relations, the securitisation of social affairs, the rise of cultural and religious tensions and the crisis of democracy? What explains their materialisation and resilience? The course aims at providing students with a comprehensive understanding of what already constitutes an international history of the most recent period in global affairs and to enhance their critical ability to assess and write in situ history.
