1836 – Sam Houston is inaugurated as the first President of the Republic of Texas
. Samuel "Sam" Houston (March 2, 1793 – July 26, 1863) was an American politician and soldier, best known for his role in bringing Texas into the United States as a constituent state. His victory at the Battle of San Jacinto secured the independence of Texas from Mexico in one of the shortest decisive battles in modern history. After the war, Houston became a key figure in Texas and was elected as the first and third President of the Republic of Texas. He supported annexation by the United States and upon achieving it in 1845, he became a U.S. Senator and finally a governor of the State of Texas in 1859. The only American to be elected governor of two states (as opposed to territories or indirect selection), Houston was also the only governor within a future Confederate state to oppose secession (which led to the outbreak of the American Civil War) and to refuse an oath of allegiance to the Confederacy, a decision that led to his removal from office by the Texas secession convention.
