Texas, situated in the South Central United States, was first inhabited by a number of Native American tribes, such as the Comanche, Caddo, and Apache. Other smaller American Indian tribes that settled in the area included the Cherokee, Tonkawa, Atakapan, Bidai, Kiowa, Wichita, Hueco, and the Karankawa of Galveston. The first European country to claim the territory of Texas was Spain. Other European and American immigrants started arriving in the area in the 1820s.
After Mexico declared its independence from Spain, the territory of Texas declared its independence from Mexico on March 2, 1836. It then existed as the independent Republic of Texas for almost ten years. Texas was added to the Union as the 28th U. S. State in the year 1845. In fact, Texas was one of the only four independent states that joined the US Federation. Annexation of Texas not only led to the Mexican-American War, but also sowed seeds for the U.S. Civil War. The Mexican-American War led to the Mexican Cession. During the American Civil War, Texas joined the Confederate States of America and was the 7th U. S. State to do so.
In the 20th century, Texas observed an economic boom owing to the discovery of oil in the state. It soon became economically diversified, with an ever-growing base in high technology. In 1994, Texas was declared the second largest state of the U.S. in terms of population. Thus, the State of Texas has a dynamic history. ‘Six Flags’ have flown over its soil until date. These include the national flags of Spain, the Fleur-de-lis of France, Mexico, the Republic of Texas, the Confederate States of America, and the United States of America. Even today, Texas is home to three major federally recognized Native American tribes, including the Alabama-Coushatta Tribe of Texas, the Kickapoo Traditional Tribe of Texas, and the Ysleta Del Sur Pueblo of Texas.
