The state boundaries between North Carolina and South Carolina were formally resolved after numerous disputes and adjustments over several centuries. Here is a brief overview of how the boundaries were officially settled:

1. Early Separation and Initial Disputes: The Carolinas were split into North and South Carolina in 1712. However, boundary disputes soon arose due to vague and inaccurate surveys.

2. 18th and 19th Century Efforts: Throughout the 18th and 19th centuries, several attempts were made to survey and establish a definite boundary line. Governors from both colonies met in London in 1730 with British commissioners to discuss boundary issues (South Carolina Historical Society).

3. 20th Century Re-Survey: The boundary line was resurveyed multiple times, each survey attempting to correct previous errors. By the 20th century, discrepancies in the border necessitated a more comprehensive solution.

4. Recent Efforts and Completion in 2013: A significant effort to re-establish the 334-mile-long boundary began in 1995. This process involved modern surveying techniques to accurately map the boundary line. The re-survey was completed on May 3, 2013. This final re-survey helped resolve long-standing ambiguities (South Carolina Geodetic Survey).
