About Texas State Historical Markers
As one of the most visible programs of the Texas Historical Commission (THC), historical markers commemorate diverse topics in Texas history, including: the history and architecture of houses, commercial and public buildings, religious congregations, and military sites; events that changed the course of local and state history; and individuals who have made lasting contributions to the state, community organizations, and businesses.
Texas has been a major oil-producing state for over a century. The first big oil discovery in Texas was the Spindletop field near Beaumont in 1901, which set off a massive oil boom that transformed the state's economy and made Texas one of the wealthiest states in the country.
