Lamar is a town in Darlington County, South Carolina, United States. The population was 1,015 at the 2000 census. It is part of the Florence Metropolitan Statistical Area. Lamar was named for a family of early settlers.
In February 1970, during a rally opposing busing of pupils for the promotion of school desegregation, militants in Lamar, armed with baseball bats and ax handles, tipped over two buses in defiance of a court order. No one was seriously injured, but police used tear gas to restore order. The incident became an issue in the 1970 gubernatorial election between Republican then U.S. Representative Albert Watson and his successful Democratic opponent, then Lieutenant Governor John C. West. Prior to the violence, Watson had told a "freedom-of-choice" rally in Lamar that the parents should "ignore those who call you racists, bigots, and hard-core rednecks." Watson adopted the slogan "Your Kind of Man"; West had warned that "no reasonable alternative [to desegregation] was feasible." Some believe the incident in Lamar contributed to West's victory in the November general election.
