However, during the late 1950s and early 1960s, the word Negro began to be criticized as having been imposed by white people, and having connotations of racial subservience and Uncle Tomism. The term Black, in contrast, denoted pride, power, and a rejection of the past. It took root first in more militant groups such as the Black Muslims and Black Panthers, and by 1967, SNCC leader Stokeley Carmichael pushed for the abandonment of Negro.
