This chapter provides an overview of how critical race theory (CRT) has provided an important context for the racial disparities in the criminal justice system. CRT has promoted teaching the history of the criminal justice system in the United States of America (USA) and abroad from a racial perceptive. CRT scholars emphasize race because of how race and racism have shaped and impacted our society and institutions. CRT has been used to understand issues from police violence, sentencing disparities, school-to-prison pipeline, prison abolitionism, and much more. The CRT framework is especially important when it comes to understanding the disparities and history of the American criminal justice and legal system which was based on racist beliefs, institutions, and laws.
