<p>This paper proposes a theoretical extension and empirical application of the concept and theory of the collective, including class, unconscious as a socio-psychological conception originating in the sociology of knowledge. It first extends this socio-psychological concept beyond the sociology of knowledge to the theory of social behavior, process, structure and change, specifically to the theory of social coercion and related phenomena, as the first or rare explicit endeavor in the literature. It posits that the collective, especially class, unconscious is a causal determinant or a process in the social determination of collective coercion and related phenomena. Then it empirically applies the concept and theory to a specific social setting, such as the American South, as also the first or rare explicit attempt in the literature. It proposes and shows that the collective, notably class, unconscious determines or influences social, including class/economic, political, individual/civic and cultural-religious, coercion and relatedly control, domination, and exclusion in the region. The paper suggests further theoretical extensions and empirical applications of the concept and theory of the collective unconscious to social theory and society.</p>
