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

Castro County History

The county was originally created  from Bexar County on August 21, 1876. It was organized in 1891, and a courthouse was built about the town square. Temporary county office space, meanwhile, was obtained from businessman J.N. Morrison. The ornate two-story courthouse was completed but was destroyed by lightning in 1906. It is named for Henri Castro, who was consul general to France for the Republic of Texas and founder of a colony in Texas. The seat of the county is Dimmitt.

Handbook of Texas Online
The area now known as Castro County was once occupied by Apaches, who were forced out of the region by Comanches around 1720. The Comanches ruled the Panhandle-Plains area until they were defeated by the United States Army in the Red River War of 1874. The Indians were confined to reservations in Indian Territory during 1875 and 1876. Buffalo hunters arrived in the region in 1876 and by the early 1880s had eliminated the last remnants of the formerly huge herds. The Texas legislature established Castro County in 1876. More at
