Aberdeen was established prior to the Civil War in 1837. During slavery, there were several free blacks that lived in the community. Laws were then passed in Mississippi that would discourage free blacks from living in town before the Civil War. This caused many blacks to leave the town out of fear. However, for those who could not leave until after the war or those who did not want to leave, there developed a settlement below Burnett Street. This community was first called “Freedman’s Town,”then later “Out South”.
