(Martinique, France, 1925 – Maryland, United States, 1965): Caribbean thinker, psychiatrist, and socialist activist. Over many travels, he developed a prolific writing and visionary thinking. In his theoretical works, developed around the 1950s, he reflected on the decolonization processes, the liberation struggles, and African nationalisms; his book Black Skin, White Masks (1952) is one of his most important writings. In it, he theorizes about the subjugating relationships that oppressed peoples suffer because of their racial status, and how the internalization of strange forms of life systematically affects and compromises the ways of thinking, feeling, saying, and making their lives. In addition, Fanon reveals the logic of subjugation, while critically expounding the reasons for the complex process of the alienation cycle and the reasons for the 'cultural whitening’ that the oppressed exert in the configuration of their subjectivity. He also emphasizes the need to build emancipation by embracing a lucid and critical conscience. In addition, he insists on explaining that the development of productive forces updates and sophisticates the various forms of exploitation of modern society. Nowadays, Fanon is known as a key radical thinker for understanding the decolonial movement and developing the psychopathology of colonization.
