political and social movement prominent in the 1960s and early '70s in the United States among some African Americans. The movement, which can be traced back to Marcus Garvey (Garvey, Marcus)'s Universal Negro Improvement Association of the 1920s, sought to acquire economic power and to infuse among blacks a sense of community and group feeling. Many adherents to black nationalism assumed the eventual creation of a separate black nation by African Americans. As an alternative to being assimilated by the American nation, which is predominantly white, black nationalists sought to maintain and promote their separate identity as a people of black ancestry. With such slogans as “black power” and “black is beautiful,” they also sought to inculcate a sense of pride among blacks.
