Mills County is located in Texas, United States. It was created on March 15, 1887, from parts of four existing counties in Central Texas—Brown, Comanche, Hamilton, and Lampasas—and named after John T. Mills. The 2020 census reported a population of 4,456. Its county seat is Goldthwaite. A long-time resident of the county quipped that residing here is the closest a person could get to living in Mayberry.
History
The Clovis are the earliest known people to inhabit the territory before Mills County, though recent discoveries indicate that people were living in the area as far back as 15,000 to 20,000 years. More recently, the Tonkawa occupied it, and numerous vestiges from their campsites remain across the county, including cooking middens. Thought to be the first White man to explore the area, Pedro Vial, visited in 1786 and 1789 while traveling between San Antonio and Santa Fe. Captain Henry S. Brown, believed to be the first white visitor, led a group to the area in 1825 to recover stolen stock. Between 1835 and 1850, the eastern part of what was to become Mills County was once encompassed by the Mexican municipality Milam (originally Viesca Municipality); the western part of the county was once a part of Bexar County between 1839 and 1848, then within Travis County between 1848 and 1852.
The Comanche regularly hunted in what became Mills County, since it was located along the southeastern edge of a large buffalo range. Native tribes moved through the area via what locals called the Comanche Trail, which led to South Texas. Starting in the 1840s, aggressive groups of Comanche and Apache pushed the Tonkawa out and raided the area in an effort to keep control of it as late as 1850, frequently stealing horses and scalping settlers who had started to move there in significant numbers after 1855. The earliest settlers arrived when the area had no fences and land was free.
Eventually, the Apache moved west, leaving the Comanche in control. Earlier, in 1835, the general council of Texas sent the first Texas Rangers to aid settlers. In 1854, the Texas Legislature appropriated land located on the Texas frontier, built a series of reservations, and moved the natives there starting in 1855, yet native incursions into White settlements continued. By the mid-1870s, native violence began to diminish, yet leading up to the 1880s, Comanche and Kiowa continued to attack the area. Comanches raided Williams Ranch in the late 1870s, the last recorded assault in the area.
The earliest communities in were Center City and Hanna Valley, both organized in 1854. One source identifies the David Morris Sr., and Dick Jenkins families as the first pioneers in the area, who settled south of present-day Center City in 1852. Killed by the natives, Dick Jenkins is thought to be the first person buried in what was to become Mills County.
Williams Ranch, established in 1855 in Brown County, was the first community that developed into a large, dynamic town after establishing trade with Mexico and serving as a major center for cattle business, capitalizing on its location near the Western Cattle Trail. The town served as the "headquarters" of the West Texas frontier and was expected to serve as the county seat. Old Fort Phantom Hill Road, the only military route that crossed Mills County, passed through Williams Ranch, connecting Austin and Fort Phantom Hill, located north of Abilene. In 1876, a telegraph line was built along the road, later to be known as the "Wire Road". The Florida Hotel (locally referred to as the Hutch Hotel) at Williams Ranch hosted a telegraph office operated by Hallie Hutchinson, the first woman telegraph operator in the U.S. The telegraph line connected Austin and Fort Concho. It was eventually replaced by a telephone line that was thought to be the longest in the United States.
A federal military facility, Camp Colorado, was established in 1856 near the community of Ebony. Numerous wagon and stage coach trails crisscrossed the area during this time. Phantom Hill Road, a military transportation and communications route that connected Fort Phantom Hill with Army headquarters in Austin, also passed through the territory.
During the Civil War and following Reconstruction, an unprecedented number of people moved west looking for a better life, attracted by plentiful and inexpensive land. Some of them settled in the area before Mills County formed and helped establish the early communities. Records demonstrate that 1876 marked the largest influx of immigrants into the area.
Most of the early settlers lived according to Christian principles they brought with them that were reinforced by religious leaders in their new communities. That said, gun altercations to settle differences were common, and legal repercussions were usually immaterial.
This isolated part of Texas, popularly referred to as a no-man's land, also attracted a variety of criminals, and minimal and often corrupt law enforcement allowed crime to surge. The first law officer was W.W. Queen, who took his position in 1883 before Mills County formed; no reliable records document the existence of law enforcement officers before then. Other sustained problems roiled the area, including native incursions, conflicts related to the cattle business, community feuds, agrarian discontent, and political unrest. This tumultuous environment was a crucible for violence. Only a few pioneers joined the Confederate Army during the Civil War because they were needed at home to fight their own "war" against the attacks of natives and outlaws.
Originally organized to protect settlers, vigilante "committees" formed with the tacit approval of law officials that degenerated into thieving, vindictive, and murderous groups that terrorized the area, killing an estimated 100 people during their reign in Central Texas. Also known as The Assembly, they were veiled in secrecy and bound by a strict code of silence, which heightened settlers' fear. The earliest one started at Williams Ranch in 1869, called the Honest Man's Club, that was supposed to rid the town of criminals. Soon, a feud erupted between it and the Trigger Mountain Mob, which was the salvo that launched the mob's rule. Groups operating in Mills County were sometimes collectively referred to as the Mills County Mob. The mob's control of the area started to subside with the arrival of the railroad in 1887, which helped usher in civilization. The Texas Rangers were eventually called to the territory in 1890 to quell the mob's depravities, though its activity continued into the early 20th century.
By 1885, the area had reached a population of 6,493 and had become civilized enough to justify forming a new county. At the time, the only significant communities were Center City, Mullin, Star, and Williams Ranch. Both Goldthwaite and Mullin were only tent villages.
Known as the Father of Mills County, district representative and Williams Ranch resident Phil H. Clements (1854–1932) lobbied in Austin for a new county in 1887, though planning for the county had started in 1885. Clements served as the first Mills County clerk and later served as county judge, county commissioner, and postmaster in Goldthwaite. He once wrote that Mills County was "the best all-the-year-round section of Texas." Opposition to creating the new county arose; Brown County, in particular, fought against it.
In an action of the 20th Texas Legislature, Governor L.S. "Sul" Ross approved H.S.S.B. No. 85 on March 15, 1887, which carved Mills County out of parts of Brown, Comanche, Hamilton, and Lampasas Counties—all of which were created much earlier in the mid-to-late 1850s. It was named after John T. Mills, honoring his service as a Republic of Texas Supreme Court justice. The bill provided directions for conducting an election to determine government leaders and the location of the county seat.
Brown County Commissioners Court met on July 25, 1887, with Brown County Judge R.P. Conner presiding, to began organizing the government of Mills County. The court created five justices' precincts and four commissioners' precincts, and assigned 10 residents to carry out the county's first election of its officials. The 10 voting places and election administrators were: Mullin, M.C. Kirkpatrick; Jon Ward's house, A.N. Perkins; Center City, F.M. Ragsdale; Parson Priddy's house, A.P. Kelly; Goldthwaite, John James; Pleasant Grove School house on Sims Creek, Phil McCormick; Big Valley, M.V. Nowell; Rock Springs, J.E. McGowan; Regency, Sam Jones; and Buffalo School house, H.G. Ratliff. The winners of the election met with Judge Conner on Monday, September 12, 1887, in Goldthwaite, to take oaths and began their duties. September 12, 1887, is recognized as the date the county was organized. The first elected officials of county were: J.B. Head, county judge; G.H. Dalton, commissioner, precinct 1; D.S. Kelly, commissioner, precinct 3; S.M. Moore, commissioner, precinct 4; George W. Cunningham, sheriff; and Phil H. Clements, county clerk. A special election held on October 10, 1889, determined Goldthwaite as the county seat, beating Mullin and Pegtown. The first legal actions at the Mills County clerk's office was to issue a marriage license and to file a divorce suit, and both transactions were instigated by Black couples.
An earlier piece of legislation, House Bill No. 421, would have created a county with a similar boundary as Mills called Key, but the bill was defeated on February 21, 1881. An early General Land Office map dated March 10, 1879, references Mills County and names a place in the center of the county, Winona.
Geography and Natural Features Located in west-central Texas near the center of the state, Mills County incorporates portions of the Limestone Cut Plain and Western Cross Timber subregions of the Cross Plains ecoregion. According to the U.S. Census Bureau, the county has a total area of , of which (0.2%) are covered by water. Elevation varies from 1,200 to 1,750 ft above meal sea level.

The county's major aquifer is the Trinity, but others include the Hickory and the Ellenberger-San Saba (southern Mills County) and the Cross Timbers (western Mills County). The Colorado River marks the county's distinctive southwestern border and creates these fertile farming valleys: Big Valley, Jones Valley, and Hanna Valley. The Pecan Bayou enters the western part of the county from Brown County, then flows east and south towards the Colorado River; Blanket and Brown Creeks unite into the Pecan Bayou along the way. From west to east, these streams drain into the Colorado River: Comanche Creek, Buffalo Creek, Rough Creek, King Creek, Pecan Bayou, Prescott Creek, Bull Creek, Nabors Creek, and Shaw Creek. North and South Bennett Creeks and Simms Creek, all in the eastern part of the county, drain into the Lampasas River. The northern parts of the county have Mountain Creek, Cowhouse Creek, and Washboard Creek that eventually drain into the Brazos River.
