Atlanta University, founded in 1865 by the American Missionary Association, with later assistance from the Freedmen’s Bureau, was, before consolidation, the nation’s oldest graduate institution serving a predominantly African-American student body. By the late 1870s, Atlanta College had begun granting bachelor’s degrees and supplying black teachers and librarians to the public schools of the South.

In 1929-30, it began offering graduate education exclusively in various liberal arts areas, and in the social and natural sciences. It gradually added professional programs in social work, library science, and business administration. At this same time, Atlanta University affiliated with Morehouse College and Spelman College in a university plan known as the Atlanta University Center.

The campus was moved to its present site, and the modern organization of the Atlanta University Center emerged, with Clark College, Morris Brown College, and the Interdenominational Theological Center joining the affiliation later. The story of the Atlanta University over the next twenty years from 1930 includes many significant developments. Graduate Schools of Library Science, Education, and Business Administration were established in 1941, 1944, and 1946, respectively.

The Atlanta School of Social Work, long associated with the university, gave up its charter in 1947 to become an integral part of the university. In 1957, the controlling Boards of the six institutions (Atlanta University; Clark, Morehouse, Morris Brown and Spelman Colleges; and Gammon Theological Seminary) ratified new Articles of Affiliation. The new contract created the Atlanta University Center. The influence of Atlanta University has been extended through professional journals and organizations, including Phylon. Through Dr. W. E. B. Du Bois, a member of the faculty, the university was also associated with the National Association for the Advancement of Colored People (NAACP).

Clark Atlanta University is a private, historically black university in Atlanta, in the U.S. state of Georgia. It was formed in 1988 with the consolidation of Clark College (founded in 1869) and Atlanta University (founded in 1865). Clark Atlanta University is a member of the United Negro College Fund (UNCF).
