Black Skin, White Masks offers a radical analysis of the psychological effects of colonization on the colonized. Fanon witnessed the effects of colonization first hand both in his birthplace, Martinique, and again later in life when he worked as a psychiatrist in another French colony, Algeria. His text is uncompromising in form and argument. He dissects the dehumanizing effects of colonialism, arguing that it destroys the native sense of identity, forcing people to adapt to an alien set of values—including a core belief that they are inferior. This results in deep psychological trauma. Fanon's work played a pivotal role in the civil rights movements of the 1960s.
