Texas Counties

Texas is divided into two hundred and fifty-four counties, more than any other state. Texas was originally divided into municipalities, a unit of local government under Spanish and Mexican rule. When the Republic of Texas gained its independence in 1836, there were 23 municipalities, which became the original Texas counties. Many of these would later be divided into new counties. The most recent county to be created was Kenedy County in 1921. The most recent county to be organized was Loving County in 1931

Cattle and sheep thrived on the well-watered range. John Arden brought the first flock of sheep from California in 1876, and in 1880 the 7D Ranch was established by Billy Childress with longhorn cattle from Atascosa County. Beginning in the 1880s a few pioneer farmers built small irrigation systems, and several ranchmen planted hay and grain. Underground water resources were tapped with windmill-driven pumps; the first cotton crop was planted in 1886 by W. H. White. In 1889 the Texas legislature formed Irion County from Tom Green County, and that same year the county was organized with Sherwood county seat. By 1890, 118 farms and ranches, encompassing 193,000 acres, had been established in the county. Though fourteen of these were larger than 1,000 acres, many were relatively small holdings; the average size was 1,627 acres. Nevertheless, ranching dominated the local economy; almost 64,000 cattle and over 42,000 sheep were reported in the county that year, when only 218 acres was planted in corn (the county's most important crop) and fourteen in cotton. The United States census counted 870 residents that year. By 1900 the number of farms and ranches declined to fifty-two, and the population dropped to 848 More at
