Theories of political behavior, as an aspect of political science, attempt to quantify and explain the influences that define a person's political views, ideology, and levels of political participation, especially in relation to the role of politicians and their impact on public opinion . Political behavior is the subset of human behavior that involves politics and power. Theorists who have had an influence on this field include Karl Deutsch and Theodor Adorno.

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.
