A new Atascosito District developed in Mexican Texas when settlers established an independent colony in 1826. Local administration of the area was conducted at Atascosito until 1831. In the battle for allegiance, some residents of the Liberty area supported the Mexican government and participated in quelling the Fredonian Rebellion.qv But the Law of April 6, 1830,qv which prohibited further American immigration, pushed settlers too far. When the Mexican government failed to recognize titles given by the Galveston Bay and Texas Land Company, settlers and squatters in the coastal area petitioned the commander-in-chief of Coahuila and Texasqv for land titles and organization of a local government. In 1831 land commissioner José Francisco Madero organized a municipality known as Villa de la Santísima Trinidad de la Libertad, which embraced most of Southeast Texas; it was bounded on the east by the Sabine River, on the west by the San Jacinto, by Nacogdoches Municipality on the north, and by the Gulf of Mexico to the south. The new seat of government, called Liberty by the Anglo-Americans, was located about three miles southwest of old Atascosito. In activities that led to the Anahuac disturbances of 1832, John Davis Bradburn, commander of the fort at Anahuac, attempted to annul the act, arrested Madero and the land commissioners who had given titles in the Liberty area, and attempted to dissolve the municipality. Nonetheless, the territory between the San Jacinto and Sabine rivers continued to be known as Liberty and functioned as a municipality. Liberty County, formed and organized in 1836 in the new Republic of Texas,qv originally included all of the future Tyler County and parts of what later became Hardin, Chambers, San Jacinto, and Polk counties. Liberty was named county seat and incorporated in 1837.
