The coloniality of power is a concept interrelating the practices and legacies of European colonialism in social orders and forms of knowledge, advanced in postcolonial studies, decoloniality, and Latin American subaltern studies, most prominently by Anibal Quijano. It identifies and describes the living legacy of colonialism in contemporary societies in the form of social discrimination that outlived formal colonialism and became integrated in succeeding social orders. The concept identifies the racial, political and social hierarchical orders imposed by European colonialism in Latin America that prescribed value to certain peoples/societies while disenfranchising others. Quijano argues that the colonial structure of power resulted in a caste system, where Spaniards were ranked at the top and those that they conquered at the bottom due to their different phenotypic traits and a culture presumed to be inferior. This categorization resulted in a persistent categorical and discriminatory discourse that was reflected in the social and economic structure of the colony, and that continues to be reflected in the structure of modern postcolonial societies. Maria Lugones expands the definition of coloniality of power by noting that it imposes values and expectations on gender as well, in particular related to the European ranking of women as inferior to men. The concept was also expanded upon by Ramón Grosfoguel, Walter Mignolo, Sylvia Wynter, Nelson Maldonado-Torres, Santiago Castro-Gómez, Catherine Walsh, and Roberto Hernández. Quijano's work on the subject "had wide repercussions among Latin American decolonial scholars in the North American academy." The Grupo modernidad/colonialidad modernity/coloniality group is an active network of intellectuals spanning generations and disciplines that are expanding on this work. Coloniality of power takes three forms: systems of hierarchies, systems of knowledge, and cultural systems. The important distinction in the concept of coloniality of power is the ways that this heterogeneous structural process shaped the modern world.
