Pre-Civil War slave rebellions were not uncommon in North Carolina. Across northeastern North Carolina in the spring of 1802 rumors of a slave uprising abounded. \"The Coleraine Letter\"Â and other plots, real or imagined, launched the worst insurrection panic in North Carolina history. The plot, however, was uncovered. Trials in Hertford and Bertie counties resulted in the hanging of eleven slaves and the whipping and deportation of others.
