City History
Seguin: Named for a Tejano Hero of the Republic
Seguin was founded in 1838 and renamed in 1839 to honor Juan N. Seguín, a Tejano leader who fought for Texas independence.
A group of Texas Rangers and settlers laid out the town in August 1838 on the Guadalupe River. They first called it Walnut Springs. In 1839 the town was renamed Seguin to honor Juan N. Seguín, a San Antonio native who served as an officer during the Texas Revolution and later as mayor of San Antonio.
Seguin incorporated in 1853 and became the Guadalupe County seat. The town grew as a cotton and trade center. By the late 1800s it had become a regional hub with railroad access, schools, and churches.
