For who did the educational system in the South benefit?

African Americans

Explanation:

The educational system in the South limited to the whites as they were superior in society. Before the Civil War, education only provided for the whites. Southerners went to boarding schools and colleges in North America or Europe to get higher education.

African Americans were slaves and part of the slavery system, which forced them to be the property of their master. After the Civil War, everything changed in the South. The slaves were freed and demanded formal education. The first postwar schools opened in 1865, and it was overflowing with the crowd. Northern freedmen's aid organizations began establishing schools in mid-1865 in the South.
