What was the most important industry in South Carolina during reconstruction?

During Reconstruction, the most important industry in South Carolina was agriculture, particularly cotton production. The state's economy was heavily dependent on cotton farming, and the majority of labor in the state was provided by newly freed African Americans who were often sharecroppers or tenant farmers working on plantations. The agricultural industry in South Carolina played a crucial role in the state's economy and continued to be the dominant industry in the years following the Civil War.
