History
Formed in 1848 from Bexar County and Nueces County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Webb County was created from Bexar and Nueces on January 28, 1848, though it was not fully organized until March 16, 1848. The county went through several boundary changes, losing territory to the creation of Zapata County in 1858 and losing land to Dimmit, Encinal, and La Salle in 1858 as well. Over the following decades, Webb's borders were adjusted through gains and losses with neighboring counties including Bexar, Zapata, and La Salle, with some jurisdictional attachments for judicial purposes.
