Founded as a freedmen's town just after the Civil War, Alpha was located on land that had been a part of Farmers Branch, Texas, on the main transportation route between Farmers Branch and Garland. The town gained a post office in 1893 and a general store in 1895. While the post office closed in 1904 as Alpha's population stood at 111, by 1933 that figure fell to 50 residents. This population would remain essentially unchanged at the 1980 census and through 1987 when the town was delisted as a community.
