During colonial times, agriculture was the basis of society in South Carolina. The head-right method and the availability of slave labor contributed to the establishment of large plantations. By 1860, South Carolina had the highest percentage of slaveholders in the nation. It is important to note that most South Carolinian's lived on family or subsistence farms. Most did not own slaves. The majority of slave owners in South Carolina owned only one or two slaves and often worked beside their slaves in the fields. Few slave owners owned large plantations. However, the economic, social, and political systems in South Carolina were based on the institution of slavery.
