County History
Robertson County Has Had Five Different County Seats
Robertson County was founded in 1837 and moved its county seat five times before settling in Franklin — a history tied to early Texas settlement and Reconstruction.
The Texas Congress created Robertson County on December 14, 1837. It was named for Sterling Robertson, a land agent who brought settlers to the region in the 1820s. The county was formed from parts of Milam, Bexar, and Nacogdoches counties.
The county seat — the town where the county government meets — moved five times. It started at Old Franklin in 1838. Then it moved to Wheelock in 1850, Owensville in 1856, and Calvert in 1870. Finally, it moved to a new town called Morgan, which was later renamed Franklin — the name was chosen to honor the original county seat. The Handbook of Texas says the rename happened when the community applied for its post office.
After the Civil War, cotton and the Houston and Texas Central Railway drove the county's growth. Cattle ranching became a key part of the local economy in later decades.
