Georgia was the last Southern state to rejoin the Union after the Civil War, in 1870, following its compliance with Reconstruction requirements.

Georgia was the final Southern state to be readmitted to the Union on July 15, 1870, after the Civil War. Its delay was due to political turmoil and resistance to Reconstruction-era policies, including ratifying the 14th Amendment, which granted citizenship and equal rights to formerly enslaved people. Georgia's initial readmission in 1868 was reversed when it expelled Black legislators from its state assembly. Federal intervention and compliance with Reconstruction mandates eventually led to its reinstatement. The state’s reentry marked the conclusion of the Southern states' reintegration into the Union, formally ending the Reconstruction period in the United States.
