What is the capital of South Carolina?

The capital of South Carolina is Columbia. Established as the state capital in 1786, Columbia was chosen for its central location within the state, making it more accessible to all residents. This decision was also influenced by the desire to create a new capital that would be an inland site, as Charleston, the previous capital, was located on the coast and faced issues related to trade and security. Columbia is home to the state government, including the governor's office and the South Carolina State House, which houses the legislature. This historical significance and the city's role in the state's governance further solidify its status as the capital.

Other options such as Charleston and Greenville are important cities in South Carolina, known for their rich history and cultural heritage, but they do not serve as the state capital. Columbia City is not an official designation of any city within the state, making it an incorrect choice as well.
