Within thirteen years of the convention, Pinckney forsook his heritage and broke with his familymost of whom were staunch Federaliststo support the Democratic-Republican Thomas Jefferson in the pivotal election of 1800. Pinckneys efforts on Jeffersons behalf helped propel the Virginian into the presidency and changed the course of American political history. As a reward, Pinckney was named minister to Spain, where he served until 1806 before returning home and to state and to national politics. Soon after suffering financial ruin in his personal life, Pinckney was elected to the U.S. House of Representatives and served during the Missouri Controversy of 1820. Pinckneys impassioned speeches in Congress helped lay the groundwork for the states rights ideology that eventually would dominate South Carolina and her southern neighbors, leading them to rebellion and civil war in 1861.
Pinckneys importance has been long overshadowed by that of luminaries such as James Madison and even by other members of the Pinckney family. In Forgotten Founder, Marty D. Matthews addresses the reasons for such oversights and examines Pinckneys many important contributions to the founding of the American republic.
