Texas is the second most populous and the second most extensive of the 50 states in the United States of America, and the most extensive state of the 48 contiguous United States. Located in the South Central United States, Texas shares an international border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south, and borders the US states of New Mexico to the west, Oklahoma to the north, Arkansas to the northeast, and Louisiana to the east. Texas has an area of 268,820 square miles, and a growing population of 25.7 million residents.

Houston is the largest city in Texas and the fourth-largest in the United States, while San Antonio is the second largest in the state and seventh largest in the United States. Dallas–Fort Worth and Greater Houston are the fourth and fifth largest United States metropolitan areas, respectively. Other major cities include El Paso and Austin—the state capital. Texas is nicknamed the Lone Star State to signify Texas as a former independent republic and as a reminder of the state's struggle for independence from Mexico. The "Lone Star" can be found on the Texas state flag and on the Texas state seal today.

Due to its size and geologic features such as the Balcones Fault, Texas contains diverse landscapes that resemble both the American South and Southwest. Although Texas is popularly associated with the Southwestern deserts, less than 10% of the land area is desert. Most of the population centers are located in areas of former prairies, grasslands, forests, and the coastline. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, and finally the desert and mountains of the Big Bend.

The term "six flags over Texas" came from the several nations that had ruled over the territory. Spain was the first European country to claim the area of Texas. France held a short-lived colony in Texas. Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845 it joined the United States as the 28th state. The state's annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state, Texas declared its secession from the United States in early 1861, joining the Confederate States of America during the American Civil War. After the war and its restoration to the Union, Texas entered a long period of economic stagnation.

One Texas industry that thrived after the Civil War was cattle. Due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The state's economic fortunes changed in the early 20th century, when oil discoveries initiated an economic boom in the state. With strong investments in universities, Texas developed a diversified economy and high tech industry in the mid-20th century. As of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the state leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace, and biomedical sciences. It leads the nation in export revenue since 2002 and has the second-highest gross state product.
