COLUMBIA, S.C. — What began as scattered calls for removing the Confederate battle flag from a single state capitol intensified with striking speed and scope on Tuesday into an emotional, nationwide movement to strip symbols of the Confederacy from public parks and buildings, license plates, Internet shopping sites and retail stores.

The South Carolina legislature, less than a week after nine parishioners were shot to death in a black church in Charleston, voted overwhelmingly on Tuesday to debate removing the Confederate flag from its State House grounds.

In Charleston, the board that governs the Citadel, the state’s 173-year-old military academy, voted, 9 to 3, to remove the Confederate Naval Jack from the campus chapel, saying that a Citadel graduate and the relatives of six employees were killed in the attack on the church.

In Tennessee, political leaders from both parties said a bust of Nathan Bedford Forrest, a Confederate general and an early Ku Klux Klan leader, should be moved out of the State House. In Virginia, Gov. Terry McAuliffe, a Democrat, ordered that the Confederate flag no longer appear on license plates, and political leaders in Maryland, North Carolina and Tennessee vowed to do the same.
