Аннотация:Until recently, the relationship between theories of international anarchy and anarchism has been ignored. Very recent work has started to bridge the gap between International Relations theory and the usefulness of anarchism and anarchist theory for the understanding of global politics. This article takes this discussion one step further by examining the relationship between classical anarchism (1860s–1940s), cosmopolitanism, post-anarchism and the global justice movement. It then investigates the linkages between the works of the 19th- and 20th-century anarchists, Rudolf Rocker and Gustav Landauer, and contemporary examinations of the linkages between cultural nationalism, cosmopolitanism and the classical and post-anarchist projects.
