The Battle of San Jacinto, fought on April 21, 1836, in present-day Harris County, Texas, was the decisive battle of the Texas Revolution. Led by General Sam Houston, the Texian Army engaged and defeated General Antonio López de Santa Anna's Mexican army in a fight that lasted just 18 minutes.

Santa Anna, the President of Mexico, was captured and surrendered the following day and held as a prisoner of war. Three weeks later, he signed the peace treaty that dictated that the Mexican army leave the region, paving the way for the Republic of Texas to become an independent country. These treaties did not specifically recognize Texas as a sovereign nation, but stipulated that Santa Anna was to lobby for such recognition in Mexico City. Sam Houston became a national celebrity, and the Texans' rallying cries from events of the war, "Remember the Alamo!" and "Remember Goliad!," became etched into Texan history and legend.
