History

Formed in 1854 from Bexar County, De Witt County, Goliad County and San Patricio County

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

Karnes County was created on February 4, 1854, from parts of Bexar, De Witt, Goliad, and San Patricio counties, and was fully organized on February 27, 1854. The county lost territory in 1857 with the creation of Bee County and again in 1860 with the creation of Wilson County.
