Gregg County is a county situated in the eastern part of the state of Texas. Longview is the county seat of Gregg County. John Gregg is the namesake of the county. He was a Confederate general who died during the American Civil War. The county itself was officially organized in 1873 from different portions of other counties. The oil boom of the county began in 1920 with the discovery of oil near the town of Kilgore. This drew many workers to the county so the population rose immensely.
