Samuel Houston ( (listen), HEW-stən; March 2, 1793 – July 26, 1863) was an American general and statesman who played an important role in the Texas Revolution. He served as the first and third president of the Republic of Texas and was one of the first two individuals to represent Texas in the United States Senate. He also served as the sixth governor of Tennessee and the seventh governor of Texas, the only individual to be elected governor of two different states in the United States.

Born in Rockbridge County, Virginia, Houston and his family migrated to Maryville, Tennessee, when Houston was a teenager. Houston later ran away from home and spent about three years living with the Cherokee, becoming known as Raven. He served under General Andrew Jackson in the War of 1812, and after the war, he presided over the removal of many Cherokee from Tennessee. With the support of Jackson and others, Houston won election to the United States House of Representatives in 1823. He strongly supported Jackson's presidential candidacies, and in 1827, Houston was elected as the governor of Tennessee. In 1829, after divorcing his first wife, Houston resigned from office, and moved to Arkansas Territory.

Houston settled in Texas in 1832. After the Battle of Gonzales, he helped organize Texas's provisional government and was selected as the top-ranking official in the Texian Army. He led the Texan Army to victory at the Battle of San Jacinto, the decisive battle in Texas's war for independence against Mexico. After the war, Houston won election in the 1836 Texas presidential election. He left office due to term limits in 1838 but won election to another term in the 1841 Texas presidential election. Houston played a key role in the annexation of Texas by the United States in 1845, and in 1846, he was elected to represent Texas in the United States Senate. He joined the Democratic Party and supported President James K. Polk's prosecution of the Mexican–American War.

His Senate record was marked by his unionism and opposition to extremists from both the

North and South. He voted for the Compromise of 1850, which settled many of the territorial issues left over from the Mexican–American War and the annexation of Texas. He later voted against the Kansas–Nebraska Act because he believed it would lead to increased sectional tensions over slavery, and his opposition to that act led him to leave the Democratic Party. He was an unsuccessful candidate for the presidential nomination of the American Party in the 1856 presidential election and the Constitutional Union Party in the 1860 presidential election. In 1859, Houston won election as the governor of Texas. In this role, he opposed secession and unsuccessfully sought to keep Texas out of the Confederate States of America. He was forced out of office in 1861 and died in 1863. Houston's name has been honored in numerous ways, and he is the eponym of the city of Houston, the fourth most populous city in the United States.
