The city of Cooper /ˈkuːpər/ is the county seat of Delta County, in the U.S. state of Texas. Located between the north and south forks of the Sulphur River, Cooper is the largest settlement within Delta County. As of the U.S. Census of 2010, Cooper had a population of 1,969.First inhabited by native people, Cooper was founded around 1870, at the same time that Delta County was established. Cooper grew rapidly and it quickly became the center of local events. The city's economy relied primarily on agricultural farming and the shipping of local goods. In the mid-1890s, a railroad line was built through the city, assisting in Cooper's growth. The city continued to grow through the 1910s, and into the early 1920s. In 1926, however, the region's cotton crop failed, devastating the local economy. Many businesses were forced to close, including the railroad, and the city's population plummeted.
