Authors such as Eric Hobsbawm, Carlton J. H. Hayes, Hans Kohn, Elie Kedourie, John Hutchinson, Ernest Gellner, Karl Deutsch, Walker Connor, Anthony D. Smith, and Benedict Anderson laid the foundation for nationalism studies in the post-war period. In the early 1990s their ideas were enthusiastically taken up by academics, journalists, and others looking to understand and explain the apparent resurgence of nationalism marked by events such as the collapse of the Soviet Union, the Rwanda genocide, and the Yugoslav Wars.
