“The Lone Star State — Independent Spirit, American Power”
Texas carries a unique and proud story: it was an independent republic before joining the United States in 1845. The Alamo and the Texas Revolution stand as defining moments of American courage and determination. Texas-born Lyndon Johnson signed the Civil Rights Act and Voting Rights Act, landmark legislation that extended equal rights and voting protections to all Americans. Today Texas is a dynamic crossroads of culture and enterprise, home to NASA’s Mission Control in Houston, a world-leading energy industry, and a rapidly growing economy that has made it one of America’s most important and influential states. Its diverse communities, vast landscapes, and entrepreneurial spirit make Texas an enduring symbol of American ambition.

Role in the Founding Era
Texas was under Spanish and then Mexican rule during the founding era. It won independence from Mexico in 1836 as the Republic of Texas and was annexed by the United States in 1845 — a controversial act that contributed to the Mexican-American War.

About Texas
Texas is the second-largest state by both area and population, with deserts, plains, pine forests, Hill Country, Gulf Coast, and large metropolitan regions. Austin is the capital, while Houston, Dallas, San Antonio, Fort Worth, and El Paso are major cities. Its size gives it strong regional variety.
The region has deep Indigenous history and was later claimed by Spain, Mexico, the Republic of Texas, and the United States. Texas won independence from Mexico in 1836, existed as an independent republic, and joined the Union in 1845. Its borderland history remains central to its identity.
Texas developed through ranching, cotton, railroads, oil, military installations, and urban growth. The discovery of oil at Spindletop in 1901 helped transform the state and the nation. Texas also became a major center for space exploration through NASA's Johnson Space Center in Houston.
Today, Texas has one of the largest state economies in the country, with strengths in energy, technology, health care, aerospace, agriculture, logistics, and international trade. It is highly diverse and fast-growing. Water, border policy, energy transition, housing, and urban expansion are major modern issues.
