Nationalism studies is an interdisciplinary academic field devoted to the study of nationalism and related issues. While nationalism has been the subject of scholarly discussion since at least the late eighteenth century, it is only since the early 1990s that it has received enough attention for a distinct field to emerge.
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.
The development of the field can be divided into four stages: (I) the late eighteenth and nineteenth centuries, when nationalism first emerged, and most interest in it was philosophical; (II) the period from the First World War until the end of the Second, when nationalism became a subject of formal academic inquiry; (III) the post-war period from 1945 to the late 1980s, when several sociologists and political scientists developed general theories of nationalism in the context of worldwide decolonization and the 'ethnic revival' in the West; and (IV) the period following the fall of communism in 1989, which led to a surge of interest in nationalism and the crystallization of nationalism studies as a field.
"Up to the First World War," Umut Özkirimli explains, "interest in nationalism was largely ethical and philosophical. The scholars of this period, predominantly historians and social philosophers, were more concerned with the 'merits and defects' of the doctrine than with the origins and spread of national phenomena." The nation-state was seen as a progressive stage in the historical development of human societies, and both liberals and Marxists expected that nationalism would eventually give way to a cosmopolitan world order.
