ABSTRACT
International Relations theory has been an independent discipline for nearly a century: the first Chair was conferred to Alfred Zimmern in 1919, by the University College of Wales, Aberystwith.1 The discipline has European origins and a universal vocation, but it is the United States who (due to its unique place in the world after 1945) largely determined its recent academic development. The first objective of this book is to construct a critical panorama of the knowledge and theories accumulated in international relations.
