The Alamo was founded in the 18th century as a Roman Catholic mission and fortress compound, and today is part of the San Antonio Missions World Heritage Site in San Antonio, TX. It was the site of the Battle of the Alamo in 1836, and is now a museum in the Alamo Plaza Historic District.
The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna reclaimed the Alamo Mission near San Antonio de Béxar (modern-day San Antonio) killing most of the Texians and Tejanos inside. Santa Anna’s cruelty during the battle inspired many Texians and Tejanos to join the Texian Army. Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the rebellion in favor of the newly-formed Republic of Texas.
