Immigrant Joseph Cotulla, who was reared in Silesia, then a part of Prussia, migrated to the United States in the 1850s. He allied the Union Army in Brownsville, Texas. He lived in Atascosa County, but arrived in La Salle County in 1868 to encourage what became a large ranching operation. After learning that the International-Great Northern Railroad intended to lay tracks in La Salle County, he worked to sustain the town that bears his name.

In 1881, Cotulla donated 120 acres of his house to the railroad, and in 1882, a depot was constructed there. In 1883, the town was approved a broadcast office. The similar year, Cotulla became the county seat by special election.

Joseph Cotulla’s great-grandson, William Lawrence Cotulla (born in the region of 1936), a former storekeeper in Cotulla, is a rancher in La Salle, Dimmit, and Webb Counties. In a 2013 interview gone the Laredo Morning Times, William Cotulla noted the community of his birth has changed unconditionally in less than 80 years, having taking into account through several phases, beginning afterward emphasis upon farming, then ranching, thereafter hunting leases, and now petroleum and natural gas through the Eagle Ford Shale boom. With declining gasoline prices, though, the Eagle Ford boom took a rasping downturn by the fall of 2015.
