History

Formed in 1835 from Jasper County

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

Jefferson County was created from Jasper on December 9, 1835, as a municipality by the Provisional Government of Texas. It became a county in the Republic of Texas in 1836 and later a county in the state of Texas in 1845. Over the following decades, Jefferson County lost territory to the creation of several new counties: Orange in 1852, Hardin in 1858, and Chambers in 1858.
