The colony of Carolina was settled by English settlers, mostly from Barbados, sent by the Lords Proprietors in 1670, followed by French Huguenots. The Carolina upcountry was settled largely by Scots-Irish migrants from Pennsylvania and Virginia, following the Great Wagon Road. The formal colony of "The Carolinas" split into two in 1712. South Carolina became a royal colony in 1729. The state declared its independence from Great Britain and set up its own government on March 15, 1776. On February 5, 1778, South Carolina became the first state to ratify the first constitution of the United States - the Articles of Confederation. South Carolina became the 8th state on May 23, 1788. South Carolina was the first state to secede from the Union on December 20, 1860. On April 12, 1861, Confederate batteries began shelling Fort Sumter and the American Civil War began. Edmund Ruffin is usually credited with firing the first shot from Battery Park (Charleston). Charleston was effectively blockaded and the Union Navy seized the Sea Islands, driving off the plantation owners and setting up an experiment in freedom for the ex-slaves. South Carolina troops participated in the major Confederate campaigns, but no major battles were fought inland. General William Tecumseh Sherman marched through the state in early 1865, destroying numerous plantations, and captured the state capital of Columbia on February 17. Fires began that night and by next morning, most of the central city was destroyed. After the war, South Carolina was reincorporated into the United States during Reconstruction. Under presidential Reconstruction (1865-66) Freedmen (former slaves) were given limited rights. Under Radical reconstruction (1867-1877), a Republican coalition of Freedmen, Carpetbaggers and Scalawags were in control, supported by Union army forces. The withdrawal of Union soldiers as part of the Compromise of 1877 ended Reconstruction and brought an era where conservative white "Redeemers" and pro-business Bourbon Democrats were in control. The state became a hotbed of racial and economic tensions during the Populist and Agrarian movements of the 1890s. Blacks were disfranchised in 1890, and "Pitchfork Ben Tillman" controlled state politics from the 1890s to 1910 with a base among poor white farmers.
