Grand Prairie was originally settled by settlers who came for the Republic of Texas land grants offered by investors in the mid-19th century. The city was established first as Dechman by Alexander Dechman in 1863. The post office opened in 1877 under the name Deckman instead of Dechman as postal workers had difficulty reading the form. There was also confusion about a T&P Railroad designation “Grand Prairie” as the name was based on maps from the 1850s labeling the area between Fort Worth and Dallas as “the grand prairie of Texas.” To clear up the confusion, the post office was then named “Grand Prairie.”
By 1909, Grand Prairie was incorporated as a city with a population of 994. Since World War I, Grand Prairie has had a history involving aviation and defense. Grand Prairie experienced the greatest increase in population between 1940 and 1970. The population grew from just 1,600 in 1940 to 14,500 in 1950 and 30,300 in 1960. The city council of Grand Prairie tried to annex undeveloped, unincorporated land in 1953 that was strongly opposed by Irving and Arlington; the measure eventually failed and Grand Prairie’s boundaries remained unchanged.
