History

Lamar was laid out in 1856. It was named for Mirabeau B. Lamar, second president of the Republic of Texas. The city suffered multiple attacks by rebels during the Civil War.

On May 28, 1919, a 28-year-old white man, Jay Lynch, was lynched in Lamar for the murders of Barton County Sheriff John Marion Harlow Jr., and his son, Dick.

Lamar was considered to be a sundown town prior to the Civil Rights era.
