History

Formed in 1856 from Kinney County

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

Maverick County was created from Kinney County but was not fully organized initially, remaining attached to Kinney for judicial and county purposes. Over the following decades, the county experienced multiple boundary adjustments, losing and gaining territory to neighboring counties including Dimmit, Zavala, Uvalde, and Kinney. Maverick was fully organized and detached from Uvalde on September 4, 1871, and Dimmit fully organized and detached from Maverick on November 2, 1880.
