Collective identity is the shared sense of belonging to a group.
In 1989, Alberto Melucci published Nomads of the Present, which introduces his model of collective identity based on studies of the social movements of the 1980s. Melucci based his ideas on the writings by Touraine and Pizzorno, specifically their ideas on social movements and collective action respectively.
Alberto Melucci writes, “collective identity is an interactive and shared definition produced by several interacting individuals who are concerned with the orientation of their action as well as the field of opportunities and constraints in which their action takes place.” Unsatisfied with the gap between theories on how collective actions form and how individuals find motivation, Melucci defines an intermediate process, in which individuals recognize that they share certain orientations in common and on that basis decide to act together. He considers collective identity as a process that is negotiated over time with three parts: cognitive definition,active relationship, and emotional investments.
Melucci, in his writing "The Process of Collective Identity" argues for collective identity as a useful analytical tool to explain social movements. It addresses not only the processes within the system of the collective actor such as leadership models, ideologies, or communication methods, but also external relations with allies and competitors which all shape the collective actor. He goes on to state that it can help better understand the development of modern collective action, distinct from formal organizations, amidst the rapid development of the field of social science research. In addition, it makes collective groups as systematic collectives and not entities of ideology or defined simple value sets that could antagonize or glorify certain groups. For conflict analysis, this distinction can change the language and nature of analysis completely.
Social psychologists had interest in concepts of identity and individuality since its early days, tracing as far back as the work of George Mead. His theories focused on the relationship between individual identity and society. He theorizes a chicken-and-egg relationship between society and identity. Preexisting social structure and conditions shape a person’s identity, which in turn, interacts with others and shapes the new and emerging social structure.
More contemporarily, Polletta and Jasper defined collective identity as “an individual’s cognitive, moral, and emotional connections with a broader community, category, practice, or institution.” The collective identity of a group are often expressed through the group’s cultures and traditions. The origin of the identity can be from within the group or outside the group, but ultimately, a collective identity is only formed upon the group members’ acceptance of the identity.Though defining collective identity to be a self-central concept, they emphasize on its distinction from concepts like ideology, motivation, and personal identity.
