History

Formed in 1841 from Robertson County and Washington County

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

Brazos County was created from Robertson and Washington counties and named after the Brazos River. Originally established as Navasoto in 1841, the county was renamed Brazos the following year and fully organized in 1843. Brazos became a county in the newly-established state of Texas in 1845.
