Critical race theory
American legal scholars started CRT in the mid-1970s. Derrick Bell, Alan Freeman, Kimberlé Crenshaw, Richard Delgado, Cheryl Harris, Charles R. Lawrence III, Mari Matsuda, and Patricia J. Williams wrote about it. It became a movement by the 1980s.  Critical race theory included some theories of critical legal studies (CLS) but it put more focus on race. CRT uses critical theory and scholars Antonio Gramsci, Sojourner Truth, Frederick Douglass, and W. E. B. DuBois are in it, as well as the Black Power, Chicano, and radical feminist movements from the 1960s and 1970s.
