How Guadalupe County Was Created
Settlers along the Guadalupe River asked the Republic of Texas Congress to create a new county. Congress set one up in 1842 and called it Guadalupe. But the Texas Supreme Court ruled that kind of county was not allowed, and the county was shut down that same year.
After Texas joined the United States, the state legislature created the current Guadalupe County in March 1846. It was carved from parts of Bexar and Gonzales counties, with Seguin as the county seat.
The county was named for the Guadalupe River. The river runs right through its center. Spanish explorer Álvar Núñez Cabeza de Vaca may have passed through the area as early as 1534. Anglo settlers came through Stephen F. Austin's and Green DeWitt's colonies in the 1820s and 1830s.
