History of Caldwell County
Around 8000 BC, Paleo-Indians hunter-gatherers inhabited the area, and later Tonkawa, Karankawa and Comanche peoples became the first identified inhabitants. Caldwell County, of Green DeWitt's petition for a land grant to establish a colony in Texas, was approved by the Mexican government in 1825. In 1839, Edmund Bellinger became the first settler of Prairie Lea, the county's oldest town. Sam Houston named the town for his future wife Margaret Lea Houston. The legislature formed Caldwell County from Bastrop and Gonzales counties in March 1845. Lockhart was named as the county seat. By 1860, the county population was 2,871, with 1,610 slaves. The community of Fentress was established, originally as Riverside, but later changed to honor the town's first physician, James Fentress. The next year, the county voted 434–188 in favor of secession from the Union.
