North Carolina was one of the thirteen British colonies that engaged in the North American Rebellion, and was incorporated into the Southern Confederation of the Confederation of North America.
Like most of the southern colonies, North Carolina was largely loyalist and escaped the organized fighting of the Rebellion. With the Trans-Oceanic War, it extended its boundary westward to the Mississippi River and its militia were involved in actions across it, even before war was declared. After the war its plantation economy prospered until exhaustion of soil led to a decline in cotton production in the 1820's. Howard's Rebellion in 1815 (which also affected Virginia and South Carolina), and further slave insurrections in 1821 and 1829, led to a vigorous debate over slavery, ending in the S.C.'s manumission bill of 1840.
In 1841 Liberal representatives from the N.C., S.C., Indiana, and Quebec met in the North Carolina city of Concordia to coordinate national policy. In August of that year this meeting issued proposals that developed into the Second Britannic Design in 1842.
North Carolina's was one of three provincial legislatures captured by the People's Coalition in the election of 1873, presaging that party's emergence as one of the two principal forces in C.N.A. politics.
