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
John Pitt, 2nd Earl of Chatham recalled in disgrace. His appearance before a parliamentary enquiry did him no favours, particularly when it emerged that he had presented the King with a private memorandum which ought to have gone to the Secretary of State for War first. Spencer Perceval's government withdrew its support from Chatham and he was forced to resign from the Ordnance in May 1810. Chatham's political and military reputation was ruined. A poem circulated making fun of his inactivity and the lack of co-operation between the army and navy: Chatham did not serve actively again, but was promoted to full General in January 1812.
