During Reconstruction, New Orleans was within the Fifth Military District of the United States. Louisiana was readmitted to the Union in 1868, and its Constitution of 1868 granted universal manhood suffrage. Both blacks and whites were elected to local and state offices. In 1872, then-lieutenant governor P.B.S. Pinchback succeeded Henry Clay Warmouth as governor of Louisiana, becoming the first non-white governor of a U.S. state, and the last African American to lead a U.S. state until Douglas Wilder's election in Virginia, 117 years later. In New Orleans, Reconstruction was marked by the Mechanics Institute race riot (1866). The city operated successfully a racially integrated public school system. Damage to levees and cities along the Mississippi River adversely affected southern crops and trade for the port city for some time, as the government tried to restore infrastructure. The nationwide Panic of 1873 also slowed economic recovery.
