Georgia's capital shifted five times before settling in Atlanta (1868): Savannah (1777) → Augusta (1778) → Louisville (1796) → Augusta (1796) → Milledgeville (1804) → Atlanta (1868). Key drivers:
As settlement expanded inland from the coast, Savannah became peripheral. Augusta, Louisville, and Milledgeville successively better reflected the population center.
Rivalry between eastern (coastal) and western (frontier) factions made the capital a bargaining chip. Moving it appeased competing power bases.
Milledgeville sat in a thriving cotton belt. Later, Atlanta's railroad hub status (Terminus → Marthasville → Atlanta) made it the economic engine, rendering Milledgeville obsolete.
Railroads shrank distances, enabling a centrally located capital (Atlanta) to govern the whole state effectively—impossible in the river/horse era.
Atlanta's capture in 1864 (Civil War) and its postwar boom cemented its role as the permanent capital of the New South.
