Tennessee Colony was established in 1847 by settlers from
Tennessee and
Alabama, who named their settlement for one of their home states. The first settlers who settled in the community had the last names Shelton, Avant, Hank, and Seagler. The community's fertile soil and moist climate made it feasible to grow
cotton, and several plantations were established, including the Jackson Plantation, which, at one time, was one of the largest
plantations in
East Texas. They were extremely successful. A post office was established at Tennessee Colony in 1852. Before the
Civil War, as well as after, the community fell victim to racial tensions. Two white men from
Mississippi named Cable and Wyrick were accused of plotting a
slave uprising in 1860, suspected of encouraging slaves to kill most of the community's white residents by poisoning the water supply in the settlement. They were tried and hanged soon after. The nearby city of
Palestine had the community's first railroad built there. As of 1884, Tennessee Colony boasted a population of 200 and three churches, a steam-powered
gristmill, and a
cotton gin. As the community's businesses moved to the nearby city of
Palestine, the community's population plummeted over the next few decades. There were a few grocers and
cotton gins in the area, and it eventually received a telephone connection. It functioned as a small cultural port in the 20th century. The population declined to just 100 people by 1914, rose again to 300 in 1927, but again declined during the 1930s. In 1941 there were 150 people in Tennessee Colony. A total of 21,000 acres of land was purchased just southwest of the settlement by the
Texas Department of Corrections in 1965, and the first medium-security
prison facility named the
Coffield Unit was built in the community and held approximately 2,000 prisoners. It reached its population zenith of 400 by that year. Then the
Beto Unit, the community's second prison, was finished in 1984. There were factories built for fabricating metal, as well as building concrete blocks and highway signs, in these prison facilities. It also had thriving
agricultural and
livestock operations. It had a steady population of 120 from the 1970s to 1990. It had a population of 300 in 2000. It currently has two historical markers, with one honoring the community, and the other commemorating the community's cemetery. It was reported that the community's first businesses included a general store, a
blacksmith shop, and a cabinet shop. Cotton was shipped on a ferry on the
Trinity River. The community traded goods to cities as far as
Dallas.
Circuit riders held church services in their homes before the first log church was built, presumably in 1838. Another was built later on. A
Masonic lodge was established in 1857. Another building that was used as a church, a school, and lodge was completed in 1860 and closed in 1948. Most of the community's current residents are descendants of the original settlers. Although Tennessee Colony is unincorporated, it has a post office, with the
ZIP code of 75861. On November 15, 2015, a deadly
mass shooting took place at a campsite between Tennessee Colony and Palestine, where
six people were killed by an intoxicated neighbor upset about losing his family's land. The shooter, William Mitchell Hudson, was charged with capital murder and was sentenced to death by a
Brazos County court on November 15, 2017. The
Los Mexicles street gang was founded in the community. ==Geography==
