Historically Black colleges and universities (HBCUs) are institutions of higher education in the United States that were established before the Civil Rights Act of 1964 with the intention of serving African American students. Most are in the Southern United States and were founded during the Reconstruction era (1865–1877) following the American Civil War. Their original purpose was to provide education for African Americans in an era when most colleges and universities in the United States did not allow Black students to enroll.
During the Reconstruction era, most historically Black colleges were founded by Protestant religious organizations. This changed in 1890 with the U.S. Congress' passage of the Second Morrill Act, which required segregated Southern states to provide African Americans with public higher education schools in order to receive the Act's benefits. Separately, during the late 20th century, either after expanding their inclusion of Black people and African Americans into their institutions or gaining the status of minority-serving institution, some institutions came to be called predominantly Black institutions (PBIs).
