Collective identities significantly shape political movements. Movements often unite individuals around shared characteristics, such as race, ethnicity, or ideology, creating a sense of belonging and purpose. This collective identity galvanizes participants, driving mobilization and advocacy for social change. For instance, civil rights movements leverage shared experiences of oppression to demand justice and policy reforms. Additionally, collective identities can inspire solidarity, as seen in protests or grassroots campaigns. However, they can also lead to polarization if identifiers are used to exclude or demonize others. Understanding these dynamics is essential for analyzing contemporary political landscapes and social movements.
