Dickinson is a city in Galveston County, Texas within the HoustonSugar LandBaytown metropolitan area. The population was 17,093 at the 2000 census. The Dickinson Land and Improvement Association was organised in the 1890s by Fred M. Nichols and eight other businessmen. It marketed to potential farmers with claims of the soil's suitability for food crops, and socialites with the creation of the Dickinson Picnic Grounds and other attractions. Dickinson is located on a tract of land granted to John Dickinson in 1824, and named after him. A settlement had been established in this area on Dickinson Bayou before 1850. The Galveston, Houston, and Henderson Railroad was built directly through Dickinson. This line was used in the American Civil War to successfully retake Galveston.
