Communication activism is a research field and academic concept that examines the strategic use of communication processes and practices by individuals, groups, and organizations to challenge existing power structures and effect social or political change. This field investigates the diverse communication strategies, tactics, and platforms employed in activist efforts, including persuasive rhetoric, media production, digital mobilization, and the construction of collective identities and narratives. Characterized by its focus on the instrumental role of communication in advocacy, resistance, and collective action aimed at transforming social norms, policies, or institutions, its significance lies in providing critical insights into the dynamics of social movements, the interplay of communication and power, and the potential for communication to serve as a tool for emancipation and social transformation.
