Chatham County, North Carolina in 1771 from Orange County. It had been named in 1758 for William Pitt, 1st Earl of Chatham, who served as British Prime Minister from 1766 to 1768 and opposed harsh colonial policies. In 1907, parts of Chatham County and Moore County were combined to form Lee County. While not devoted to large plantations, the county was developed for small farms, where slave labor was integral to the owners' productivity and success. By 1860 one-third of the county population were African Americans, chiefly enslaved. George Moses Horton, Historic Poet Laureate of Chatham County, (1797?-1883) lived most of his life enslaved
William Pitt, 1st Earl of Chatham from 1756 to 1761 (with a brief interlude in 1757), during the Seven Years' War (known as the French and Indian War in the United States). He again led the ministry, holding the official title of Lord Privy Seal, between 1766 and 1768. Much of his power came from his brilliant oratory. He was out of power for most of his career and became well known for his attacks on the government, such as those on Walpole's corruption in the 1730s, Hanoverian subsidies in the 1740s, peace with France in the 1760s, and the uncompromising policy towards the American colonies
