One of the leading families of colonial South Carolina and the early republic, the Pinckneys of Charleston were witnesses to—and often active participants in—many of the defining customs and transforming events of the early national South. This digital resource collects, for the first time, the papers of three of the most notable Pinckneys: brothers Charles Cotesworth Pinckney (1746–1825) and Thomas Pinckney (1750–1828) and their cousin Charles Pinckney (1757–1824). They served variously as young officers during the American Revolution, governors of the state of South Carolina, delegates to the Constitutional Convention, leading lawyers and businessmen in Charleston, and diplomats to England, France, and Spain.
