Colonization and decolonization continue to be debated both in terms of their meaning and their efficacy in Communication Studies scholarship and across related fields of inquiry. Colonization is part of ongoing processes of subjugation that are linked to other forms of oppression including labor, occupation, and resource extraction. Inquiries about processes of colonization also involve examining corresponding efforts in decolonization processes. Decolonization entails an effort to critically reflect on colonialism and its impact upon colonized people and environments, it involves processes entangled with issues of sovereignty, self-determination, and territory, and so on. Indigenous Studies scholarship helps to foreground Indigeneity as a place from which broader inquiries on colonization and decolonization may be launched. The legitimacy of colonialism and its communicative dimensions has been a concern for scholars. Within the field of Communication, it notes particular contexts of colonization inquiry that overlap across topics and various areas of the discipline. Research on colonialism and its influence spans throughout rhetorical theory and critical/cultural studies to organizational communication and global communication. This scholarship has employed expansive methodologies from applied research to theoretical work and considered a wide range of issues from domestic, international, and transnational perspectives. The study of these powerful structures in rhetoric draws on interdisciplinary fields and raises challenges to intellectual traditions of the West, which have maintained the rhetoric canon. Rhetorical scholars call for the need to examine artifacts that exist at the “margins” and “outside” the imperial centers. They have theorized methods of rhetorical analysis that attend to the colonial and decolonial elements of discourse, power, and identity.
