Oldham County, Texas

Oldham County is a county located in the U.S. state of Texas. As of the 2020 census, its population was 1,758. Its county seat is Vega. The county was created in 1876 and organized in 1881. Oldham County is included in the Amarillo, TX Metropolitan Statistical Area.

History
Oldham County was formed in 1876 and organized in 1881, and named for Williamson Simpson Oldham, Sr., a Texas pioneer and Confederate Senator. At the time of its organization, about half of the county was a part of the XIT Ranch. The county seat was originally at the town of Tascosa, Texas, which in the 1880s was one of the largest towns in the Panhandle. As the railroads came through the county, however, they bypassed Tascosa; several new towns and farms sprang up along the rail lines, and by 1915 Tascosa had a courthouse and almost no residents; the county seat was moved to Vega that year. Oldham County is primarily ranch and farm land, with many thousands of acres planted in wheat, the major crop. The county also has some petroleum production and large wind farms.

Geography
According to the U.S. Census Bureau, the county has a total area of 1501 sqmi, of which 1501 sqmi is land and 0.9 sqmi (0.06%) is water. A southern strip of the county, including the county seat, Vega, is located on top of the Llano Estacado (Staked Plains). The next stretch, comprising approximately 12 miles, slopes down to the Canadian River. The former county seat of Tascosa is located at a crossing of the Canadian River, north of Vega. The terrain then slopes up from the Canadian River, passing the county line at approximately six miles and reaching the top of the High Plains a further four miles north.

Border dispute with New Mexico
For years, there has been a simmering dispute over a strip of land running north and south, including an abandoned part of Glenrio at the western end of Oldham County, as to which state it is lawfully a part of. The border between the two states was originally defined as the 103rd meridian, but the 1859 survey that was supposed to mark that boundary mistakenly set the border between 2.29 and 3.77 miles too far west of that line, making the current towns of Farwell, Texline and the eastern part of Glenrio appear to be within the State of Texas. New Mexico's short border with Oklahoma, in contrast, was surveyed on the correct meridian. New Mexico's draft constitution in 1910 stated that the border is on the 103rd meridian as intended. The disputed strip, hundreds of miles long, includes parts of valuable oilfields of the Permian Basin. A bill was passed in the New Mexico Senate to fund and file a lawsuit in the U.S. Supreme Court to recover the strip from Texas, but the bill did not become law.

The question was once settled in favor of Texas by the intervention of President William Howard Taft, at the request of Senator John Villiers Farwell, whose three-million-acre XIT Ranch would have been diminished by New Mexico's claim. With Taft's support, on February 16, 1911, the Joint Resolution of Congress on admitting New Mexico as a state declared that any provision of New Mexico's constitution that "...in any way tends to annul or change the boundary lines between the State of Texas and Territory of New Mexico shall be of no force and effect."

Today, land in the strip is included in Texas land surveys, and the land and towns (the east part of Glenrio in Deaf Smith and Oldham Counties) for all purposes are taxed and governed by the State of Texas.
