History

Formed in 1837 from Austin County, Brazoria County, Harrisburg County and Harris County

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

Fort Bend County was created on December 29, 1837, from Austin, Brazoria, Harrisburg (now Harris), and Harris counties, and was fully organized on January 13, 1838. The county became part of the newly-established state of Texas on December 29, 1845. Over the following decades, Fort Bend gained and lost territory through boundary adjustments with neighboring counties, including a boundary dispute with Austin and Brazoria settled in 1931.
