Enrique Dussel argues that the theme of epistemological decolonization has originated from a group of Latin American thinkers.[7] Although the notion of decolonization of knowledge has been an academic topic since the seventies, Walter Mignolo argues that it was the ingenious work of Peruvian sociologist Anibal Quijano that "explicitly linked coloniality of power in the political and economic spheres with the coloniality of knowledge."[8] It developed as "an elaboration of a problematic" that began because of a number of critical positions such as postcolonialism, subaltern studies and postmodernism.
