Collective identities significantly influence social movements by uniting individuals under shared beliefs, experiences, or goals. These identities, shaped by factors such as race, ethnicity, gender, or socioeconomic status, create a sense of belonging and solidarity. By fostering connections within a group, collective identities motivate individuals to engage in activism and advocate for change. When people see themselves as part of a larger community struggling for a common cause, they are more likely to mobilize resources and participate in protests, campaigns, or other forms of political action. This unity amplifies their voices and can lead to significant societal transformations.
