Texas Revolution: A day after the Battle of San Jacinto, forces under Texas General Sam Houston identify Mexican General Antonio López de Santa Anna among the captives of the battle when some of his fellow soldiers mistakenly give away his identity.

The Texas Revolution was a rebellion of colonists from the United States and Tejanos against the centralist government of Mexico in the Mexican state of Coahuila y Tejas. Although the uprising was part of a larger one, the Mexican Federalist War, that included other provinces opposed to the regime of President Antonio López de Santa Anna, the Mexican government believed the United States had instigated the Texas insurrection with the goal of annexation. The Mexican Congress passed the Tornel Decree, declaring that any foreigners fighting against Mexican troops "will be deemed pirates and dealt with as such, being citizens of no nation presently at war with the Republic and fighting under no recognized flag". Only the province of Texas succeeded in breaking with Mexico, establishing the Republic of Texas. It was eventually annexed by the United States about a decade later.

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.

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.
