Abstract
This chapter examines the origins and development of the field of peace studies after the Second World War, initially in relation to the East–West confrontation and the nuclear arms race. It analyses how peace studies responded to the issues of socio-economic disparities and environmental constraints as they became apparent in the 1970s, and explores its development as an interdisciplinary and problem-oriented field of study, often in the midst of controversy. The chapter then assesses the state of peace studies now, before concluding by examining how it is especially relevant to the new security challenges facing the world.
