Tejanos have been central to Bexar County from its founding through the Texas Revolution

Tejano history starts early in Bexar County. TSHA traces Mission San Antonio de Valero and the San Antonio de Béxar presidio to 1718. It traces the Canary Islanders' arrival to 1731.

Juan Nepomuceno Seguín was born in San Antonio in 1806. After Gonzales, Stephen F. Austin made him a captain. He entered the Alamo with the Texan force, left as a courier, and later fought at San Jacinto with his Tejano company.

Seguín accepted the Mexican surrender of San Antonio. He served as military commander, won election to the Texas Senate, and later became mayor. His story keeps Bexar County history tied to local families, not just landmarks.
