Due to the maintenance of the imbalanced apportionment scheme, many Upstate residents proved dissatisfied with the constitution. In 1794, a number of prominent Upstate residents, including Wade Hampton I and John Kershaw, formed the Representative Reform Association to challenge the system. Initially, the Lowcountry-dominated legislature rejected their appeals. However, the Upcountry residents, aligned with the newly ascendant Democratic-Republican Party, eventually prevailed. In 1808, the constitution was amended to create an apportionment system based on the total white population, substantially alleviating many of the issues. Further amendments to the constitution were later adopted. Most significantly, in 1810, an amendment granted the suffrage to all white men over the age of twenty-one.
