Tejano History
Starr County has deep Tejano and Spanish ranching roots
Spanish settlement in 1749 built a ranching culture that shaped Starr County's land, economy, and Hispanic majority population for generations.
Spanish colonizer José de Escandón led settlement efforts in this region in 1749. Francisco de la Garza Martínez founded one of the first settlements here in 1763. Ranching — cattle and sheep — was the backbone of the local economy from the start.
The county's population has been predominantly Hispanic since at least the 1870s. By 1985, Mexican Americans made up about 97 percent of the county's population. The county is named for James Harper Starr, a Republic of Texas official. But the culture and daily life here have always reflected its Spanish and Mexican heritage.
Rio Grande City was founded in 1847 by Henry Clay Davis. Davis was a Kentucky frontiersman who survived the Mier Expedition and married into the local Garza family. The Handbook of Texas covers this history in detail.
