What do Texas call themselves?

Excuse me, could you clarify what you mean by "What do Texas call themselves?"? Texas is a state in the United States of America, not a person or group that would have a self-proclaimed name or title. Perhaps you're asking about the nickname or common moniker used to describe Texas or its residents? If so, Texas is often referred to as the "Lone Star State" due to the single star on its flag, which represents the state's independence and resilience. Is that the information you were seeking?
