The county was established by the state legislature on March 13, 1874, and named afterThomas Green, a Texas revolutionary and aConfederatebrigadier general. It originally comprised an area over 60,000 sq mi (160,000 km2).
The original county seat was the town ofBen Ficklin. In 1882, flood waters of theConcho River destroyed the town and drowned 65 people. The county seat was moved to Santa Angela. In 1883, the town's name was officially changed toSan Angelo by theUnited States Post Office. Following completion of theSanta Fe Railway in September 1888, the county increased its cattle production to an estimated export of 3,500 to 5,000railroad cars. In 1889, San Angelo became incorporated to a city, andFort Concho shut down after 22 years of operation.[4]
Tom Green County has a long, narrow strip of land extending to the west. This unusual feature is becauseReagan County to the west used to be part of Tom Green County, and the state of Texas required that all counties have a contiguous land route to their county seat. The small strip of land served to connect the two main regions. In 1903, the residents of the western section voted to form Reagan County, while the same vote decided that the connecting strip would remain part of Tom Green County.[5]
