How was the colony originally known as Carolina governed and how did it become divided into what we know as north and south carolina

Carolina was governed by 8 nobles who received a royal charter from Charles II to settle there and do as they wish. Carolina acted as a buffer between spanish controlled Florida and the British Colonies until Georgia was founded. It was divided into two separate colonies due to significant differences in government, population, and internal disputes between the 8 nobles. North Carolina progressed a little slower than South Carolina, but after the Civil War it was North Carolina who grew the fastest, being the most progressive of the southern states. Tobacco, Rice and Indigo were the Carolina's most major crops and exports.
