Spaniards first introduced the Catholic faith into this region when conquistador Francisco Vasquez de Coronado passed through in a 1540s expedition to conquer the fabled cities of gold, and he and his men rested at a campsite in Blanco Canyon, southeast of present-day Floydada. The South Plains later came under the care of the Mexican Diocese of Linares, and after this became United States territory, the area came under the jurisdiction of an American bishop who extended direct pastoral care. In 1890, the Catholic Church created the Dallas Diocese, which attended to this region. By the early 1900s, Father David H. Dunn ministered to area Catholics, many of whom were immigrants responding to the availability of land in West Texas, while other Catholics arrived from Mexico during the Mexican Revolution. By 1908, the first Catholic church in the future Diocese of Lubbock was built in Hermleigh, and soon circuit-riding priests ministered in the area. In 1926, the Catholic Church established the Diocese of Amarillo, and church growth continued in the following decades. The 1950s was the most productive decade of area church building, partially attributed to the Bracero program, in which hundreds of thousands of workers emigrated from Mexico into the U.S. each year, and church building continued at a high rate into the 1970s. In 1983, the Vatican established the Diocese of Lubbock, formed from 20 counties of the Diocese of Amarillo and five from the Diocese of San Angelo, which was created in 1961. Today, the Diocese of Lubbock continues to serve the spiritual needs of Catholics in the region.
