The Carolina League is a Minor League Baseball affiliation which operates along the Atlantic Coast of the United States. It is classified as a "Class A-Advanced" league. The organization that later became the Carolina League formed in 1945, just as World War II was ending, and consisted of only two teams based in southern Virginia. Historically, however, as many as 12 teams in a given year have competed in the Carolina League. Today, the league consists of ten teams in a region stretching from Delaware to South Carolina, and is divided into a Northern Division and a Southern Division.
