The county of Robertson, located in the east-central region of the Texas State, was established in 1837 and organized in 1838. It was named after Sterling Clack Robertson, an empresario and a signatory in the Texas Declaration of Independence. Robertson County has been economically dependent on its agriculture and oil industries; beef cattle, poultry, cotton, corn, and hay were its major agricultural products. It also features interesting historical and recreational sites from the Hearne Railroad Museum Depot to the Lake Limestone and Twin Oaks Reservoir. Hence, tourism also plays a significant role in its economy; the city of Hearne holds an annual county fair and the city of Calvert hosts an annual Maypole Festival. Furthermore, the county of Robertson offers a variety of food selection from steaks, seafood, barbecues, and other Greek, Korean, Mexican, and Italian specialties.
