In this racial structure inferiority and superiority was ascribed based on phenotypes and skin colors, what colonialists claimed to be innate biological traits. This system was the outcome of a Eurocentric view that reinforced the justification for the domination of Europeans, overriding the previously used gender-based domination systems. As Lugones points out, however, the gender-based domination system did not disappear, but was integrated into the race-based hierarchical domination system. The importance of the systems of hierarchies was not merely symbolic, but was instead economic. A racial division of labor was built around the hierarchies created, resulting in a system of serfdom for the majority of native people. Existing differences were exploited in the formation of these hierarchies. Quijano (p. 536) notes that: "In some cases, the Indian nobility, a reduced minority, was exempted from serfdom and received special treatment owing to their roles as intermediaries with the dominant race... However, blacks were reduced to slavery." Coloniality of power is based on a Eurocentric system of knowledge, in which race is seen as "naturalization of colonial relations between Europeans and non-Europeans. The Eurocentric system of knowledge assigned production of knowledge to Europeans and prioritized the use of European ways of knowledge production. Quijano writes, "Europe’s hegemony over the new model of global power concentrated all forms of the control of subjectivity, culture,and especially knowledge and the production of knowledge under its hegemony." This resulted in a simultaneous denial of knowledge production to the conquered peoples and repression of traditional modes of knowledge production, on the basis of the superiority/inferiority relationship enforced by the hierarchical structure. The third element of coloniality of power is the creation of cultural systems that revolve around a Eurocentric hierarchy and that enforce Eurocentric economic and knowledge production systems. The concept of coloniality of power as illustrated by Quijano, Grosfuguel and others describes the existing global neoliberal system of capital and labor and locates its roots in the racist, patriarchal logic of the colonial system. The cultural systems created under coloniality of power presume that European cultures are the only truly modern cultures, based on characteristics of modernity like capitalist economic systems, rationality, neoliberalism, and science. These cultural systems enforce Eurocentric norms through the use of the state and the economic system. One example of this type of repression is the Chilean Mapuche culture, in which genders are interchangeable and combinable, not static and prescribed like in Chilean mainstream culture (reflective of incas norms) The enforcement of the gender binary by the state, which correlates the masculine with the political sphere and the feminine with the private sphere, has had the effect of repressing the Machi gender expression.
