full_context: Document 1: North Carolina: On November 21, 1789, North Carolina became the twelfth state to ratify the Constitution. In 1840, it completed the state capitol building in Raleigh, still standing today. Most of North Carolina's slave owners and large plantations were located in the eastern portion of the state. Although North Carolina's plantation system was smaller and less cohesive than that of Virginia, Georgia, or South Carolina, significant numbers of planters were concentrated in the counties around the port cities of Wilmington and Edenton, as well as suburban planters around the cities of Raleigh, Charlotte, and Durham in the Piedmont. Planters owning large estates wielded significant political and socio - economic power in antebellum North Carolina, which was a slave society. They placed their interests above those of the generally non-slave - holding ``yeoman ''farmers of western North Carolina. In mid-century, the state's rural and commercial areas were connected by the construction of a 129 - mile (208 km) wooden plank road, known as a`` farmer's railroad'', from Fayetteville in the east to Bethania (northwest of Winston - Salem).

Document 3: North Carolina: After 1800, cotton and tobacco became important export crops. The eastern half of the state, especially the Tidewater region, developed a slave society based on a plantation system and slave labor. Many free people of color migrated to the frontier along with their European-American neighbors, where the social system was looser. By 1810, nearly 3 percent of the free population consisted of free people of color, who numbered slightly more than 10,000. The western areas were dominated by white families, especially Scots-Irish, who operated small subsistence farms. In the early national period, the state became a center of Jeffersonian and Jacksonian democracy, with a strong Whig presence, especially in the West. After Nat Turner's slave uprising in 1831, North Carolina and other southern states reduced the rights of free blacks. In 1835 the legislature withdrew their right to vote.
