Because of the Union forces, Pine Bluff attracted many refugees and freedmen after the Emancipation Proclamation was issued in early 1863. The Union forces set up a contraband camp there to house the runaway slaves and refugees behind Confederate lines. After the war, freed slaves worked with the American Missionary Association to start schools for the education of blacks, who had been prohibited from learning to read and write by southern laws. Both adults and children eagerly started learning. By September 1872, Professor Joseph C. Corbin opened the Branch Normal School of the Arkansas Industrial University, a historically black college. Founded as Arkansas's first black public college, today it is the University of Arkansas at Pine Bluff.
