Post-WWII, Georgia saw major agricultural and economic transformations as people moved away from small farms to cities and suburbs. Atlanta in particular grew significantly, establishing itself as a regional center for business, medicine, and entertainment. Under progressive mayors like William Hartsfield and Ivan Allen Jr., Atlanta pursued policies of racial integration and urban development, building new infrastructure like Hartsfield Airport and MARTA. These changes modernized Georgia and fueled Atlanta's rise as a dominant Southern city.
