Columbia is the capital of the U.S. state of South Carolina and the second-most populous city in the state. With an estimated population of 147,035 in 2025, it is the principal city of the Columbia metropolitan area, the second-largest metropolitan area in South Carolina, with an estimated population of 879,918 in 2025. Columbia serves as the county seat of Richland County, while portions of the city extend into neighboring Lexington and Kershaw counties. The city's name derives from "Columbia", a historic poetic personification of the United States, and is commonly shortened to "Cola", inspiring the nickname "Soda City".
Located near the geographic center of South Carolina at the fall line, Columbia developed at the confluence of the Broad and Saluda rivers, which form the Congaree River. Established in 1786 as South Carolina's first planned capital city, it has served as the seat of state government for more than two centuries and is home to the South Carolina State House. During the American Civil War, much of the city was destroyed in the burning of Columbia in 1865 before being rebuilt during Reconstruction.
Columbia is home to the University of South Carolina, the state's flagship public university, and Fort Jackson, the U.S. Army's largest basic combat training installation. State government, higher education, healthcare, military activities, insurance, and manufacturing form the foundation of the regional economy, while recent decades have seen significant investment in the Congaree Vista, Main Street, and the BullStreet District.
The city is a major cultural center for South Carolina, with institutions including the South Carolina State Museum, Columbia Museum of Art, and Riverbanks Zoo & Garden. Columbia also serves as a regional center for collegiate athletics through the University of South Carolina and provides access to outdoor recreation along the Three Rivers Greenway, Congaree National Park, and Lake Murray.
In May 1540, a Spanish expedition led by Hernando de Soto traversed what is now Columbia while exploring the interior of the southeastern United States. The expedition produced the earliest surviving written account of the area, then part of the regional Cofitachequi chiefdom of the Mississippian culture.
During the colonial era, the Congaree inhabited several villages along the Congaree River, where the Broad and Saluda rivers converge to form the Congaree River. As English settlement expanded into the South Carolina backcountry during the eighteenth century, colonists established Congaree Fort on the river's west bank as a frontier outpost and trading post. In 1754, the colonial government of the Province of South Carolina established a ferry connecting the fort with the growing settlements on the east bank, encouraging further settlement in the surrounding area.
The settlement occupied a strategic location at the fall line, where rivers descending from the Piedmont become difficult to navigate farther upstream. As the head of navigation on the Santee River system and a natural crossing point between South Carolina's coastal and interior regions, the area developed into an important transportation and trading center long before the General Assembly selected the site for the new state capital in 1786.
Following the American Revolutionary War, South Carolina leaders sought a more centrally located capital than Charleston. State Senator John Lewis Gervais of Ninety Six introduced legislation establishing a new state capital, which was approved by the General Assembly on March 22, 1786. The site, known as Taylor's Hill, was selected for its central location within the state and its position along the Congaree River at the head of navigation on the Santee River system.
Surveyor John Guignard laid out Columbia as one of the first planned cities in the United States, five years before Pierre Charles L'Enfant's plan for Washington, D.C. The city was organized as a two-mile-square grid of 400 blocks with unusually broad streets and avenues. Assembly and Senate streets were each 150 feet (46 m) wide, while the remaining streets measured 100 feet (30 m). Blocks were divided into half-acre lots that were sold to prospective residents, with commissioners reserving prominent sites for public buildings, including the State House.
Construction of Columbia's first State House began in 1786, and the General Assembly first met in the new capital in 1790. The city continued to expand its role as South Carolina's political and educational center with the founding of South Carolina College (now the University of South Carolina) in 1801. The college was intended to help unite the state's Upcountry and Lowcountry populations after the Revolution, and for many years its commencement exercises were held while the General Assembly was in session.
Transportation improvements accelerated Columbia's growth during the early nineteenth century. The Santee Canal, completed in 1800, established a direct inland water route to Charleston and was among the earliest canals constructed in the United States. By the 1840s, railroads had largely supplanted canal traffic, transforming Columbia into a transportation hub for central South Carolina and strengthening its commercial connections with regional and national markets.
Columbia was incorporated as a town in 1805, with John Taylor serving as its first elected intendant, and was chartered as a city in 1854. Throughout the antebellum period, Columbia grew steadily as a center of government, commerce, and education. Cotton became the city's principal commodity, with railroads carrying bales to Charleston for export to textile mills in the northeastern United States and Europe. Like much of South Carolina's economy, the city's prosperity depended upon enslaved labor. Around 1,500 enslaved people lived and worked in Columbia in 1830; by 1860 that number had grown to approximately 3,300. Enslaved laborers worked in households, businesses, government institutions, and South Carolina College, where many were hired out by their owners.
Columbia was of considerable importance to the Confederacy during the American Civil War as South Carolina's capital and a center of government, transportation, and military production. Columbia was the site of the first Southern secession convention, which assembled in the First Baptist Church on December 17, 1860. Secession may have been declared in Columbia, were it not for a smallpox outbreak that moved the convention to Charleston, where South Carolina became the first state to secede from the Union on December 20.
A considerable military infrastructure sprang up in Columbia during the war. The state arsenal was located in the city, along with the state military academy, while the University of South Carolina grounds were converted into a military hospital after nearly its entire student body volunteered for the Confederate Army. Numerous industrial facilities produced war materiel, and by 1865 Columbia had also become the Confederacy's last major breadbasket. These factors made it the next target for General William T. Sherman following his successful March to the Sea and capture of Savannah, Georgia.
The Union Army under Sherman captured Columbia on February 17, 1865. Much of the city was destroyed by fire between February 17 and 18. The idea that Sherman deliberately ordered the burning of Columbia has persisted as part of the Lost Cause of the Confederacy narrative; however, modern historians have concluded that no single cause led to the fire and that Sherman did not order the city burned. Rather, retreating Confederates, burning cotton bales, strong winds, and the chaotic conditions following the city's capture combined to create the conditions that allowed the fire to spread. As a newspaper columnist observed in 1874, "the war burned Columbia."
During the Reconstruction era, Columbia became the center of South Carolina's Republican state government. Reporters, journalists, travelers, and tourists flocked to the city to observe a legislature whose members included formerly enslaved African Americans as well as free people of color. The city also began rebuilding from the destruction of 1865; a modest construction boom, together with the repair of railroads serving the city, restored Columbia's commercial district and laid the foundation for its late nineteenth-century industrial growth.
