Marxist concepts of
class consciousness can be considered a root of one form of political collective identity. The identity of the class was tied to its values and interests, and includes
solidarity. This idea of solidarity is shared by
Émile Durkheim, who argues that collective identity helps create bonds between individuals through shared morals and goals.
Max Weber, in his book "
Economy and Society", published posthumously in 1922, critiqued Marx's focus on production and instead suggests that class, status, and party form the three sources of collective identity.
Alexander Wendt is well known for his writings on constructivist political theory, in which collective identity play a prominent role as identity is a major determining factor in the role of states in the international order. His approach focuses on group and individual identity, at the domestic and international level. This application of collective identity to explaining and describing the international system is the basis of constructivism.
Constructivism has a strong focus on the social discourse that create these identities, which not only designate a country as a collective actor but possible alliances as collective groups. By grouping together countries, either by their own decision or by third parties, new alliances or blocs form through the collective identity assigned to them, even if sometimes this assignment is based on inaccurate binary groupings. Regardless of accuracy of grouping, the very act of grouping these countries together affects how the international system views them and thus treats them, which in return causes the countries to identify with each other in terms of their common position internationally. Further work on collective identity in international relations has been conducted by
Richard Ned Lebow, who has argued that states view themselves and others as parts of collective power groups of states, such as rising and falling powers, and simply their sense of belonging to certain power groups or aspiring to be in others affects their interactions with other states, irrespective of the "reality" of their power statuses. That is the case, very often. ==Evolutionary function==
