History

Formed in 1858 from Maverick County and Uvalde County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Zavala County was named after Lorenzo de Zavala. Created in 1858 from Maverick, Uvalde, and Bexar Land District, Zavala was not fully organized at first and was attached to other counties for judicial purposes for several decades. The county gained territory from Maverick in 1866 and was fully organized in 1884 when it detached from Frio County.
