Black Buck
Black Buck is a stereotype of an African American male: large, violent, and voraciously attracted to white women. It is closely related to the African American stereotype of the black brute.
According to the National Museum of African American History and Culture, the stereotype originated as White Americans feared freed African American males would attempt to exact revenge for slavery against white men by having sex with their daughters, while Riché Richardson says it was created at the end of the 19th century to justify lynching African Americans.
The stereotype has been depicted in films to reflect negatively on African Americans such as The Birth of a Nation (1915) and to reflect positively such as Sweet Sweetback's Baadasssss Song (1971), although it has been challenged by some in the African American community as to whether these depictions are good.
