Anthony D. Smith in the context of "Interdisciplinarity"

A nation is a type of social organization where a collective identity, a national identity, has emerged from a combination of shared features across a given population, such as language, history, ethnicity, culture, territory, or society. Some nations are constructed around ethnicity (see ethnic nationalism) while others are bound by political constitutions (see civic nationalism).

A nation is generally more overtly political than an ethnic group. Benedict Anderson defines a nation as "an imagined political community […] imagined because the members of even the smallest nation will never know most of their fellow-members, meet them, or even hear of them, yet in the minds of each lives the image of their communion", while Anthony D. Smith defines nations as cultural-political communities that have become conscious of their autonomy, unity and particular interests. Black's Law Dictionary also defines nation as a community of people inhabiting a defined territory and organized under an independent government. Thus, nation can be synonymous with state or country. Indeed, according to Thomas Hylland Eriksen, what distinguishes nations from other forms of collective identity, like ethnicity, is this very relationship with the state.

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.

Walker F. Connor (June 19, 1926 – February 28, 2017) was Distinguished Visiting Professor of Political Science at Middlebury College (Middlebury, Vermont, USA). Connor is best known for his work on nationalism, and is considered one of the founders of the interdisciplinary field of nationalism studies.

Before the collapse of European communism that began in the late 1980s, nationalism was not a subject of significant academic study and was generally neglected, with the exception of some major contributions by authors such as Ernest Gellner, Benedict Anderson, and Anthony D. Smith. Connor’s work is another exception to this rule, and today he is regarded as “one of the scholars of nationalism and ethnic conflict who has contributed most towards establishing a conceptual grounding” for the study of nationalism.
