Forces of the Republic of Texas led by Sam Houston defeated the Mexican troops of General Antonio López de Santa Anna in the Battle of San Jacinto, the decisive and final battle of the Texas Revolution.

The Republic of Texas, or simply Texas, was a country in North America that existed for close to 10 years, from March 2, 1836, to February 19, 1846. Texas shared borders with Centralist Republic of Mexico, the Republic of the Rio Grande, and the United States. The Republic declared its independence from Mexico with the proclamation of the Texas Declaration of Independence, subsequently beginning the Texas Revolution. The proclamation was established after the Centralist Republic of Mexico abolished autonomy from states of the Mexican federal republic. The revolution lasted for six months, with major fighting ending on April 21, 1836, securing independence.

Samuel Houston was an American general and statesman who played a prominent 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.

Antonio de Padua María Severino López de Santa Anna y Pérez de Lebrón, often known as Santa Anna, was a Mexican general, politician, and caudillo who served as the 8th president of Mexico on multiple occasions between 1833 and 1855. He also served as vice president of Mexico from 1837 to 1839. He was a controversial and pivotal figure in Mexican politics during the 19th century, to the point that he has been called an "uncrowned monarch", and historians often refer to the three decades after Mexican independence as the "Age of Santa Anna".

The Battle of San Jacinto, fought on April 21, 1836, in present-day La Porte and Deer Park, Texas, was the final and decisive battle of the Texas Revolution. Led by General Samuel Houston, the Texan Army engaged and defeated General Antonio López de Santa Anna's Mexican army in a fight that lasted just 18 minutes. A detailed, first-hand account of the battle was written by General Houston from the headquarters of the Texan Army in San Jacinto on April 25, 1836. Numerous secondary analyses and interpretations have followed.
