The Texas Revolution or Texas War of Independence was a military conflict between Mexico and settlers in the Texas portion of the Mexican state Coahuila y Tejas. The war lasted from October 2, 1835 to April 21, 1836. However, a war at sea between Mexico and Texas would continue into the 1840s. Animosity between the Mexican government and the American settlers in Texas, as well as many Texas residents of Mexican ancestry, began with the Siete Leyes of 1835, when Mexican President and General Antonio López de Santa Anna abolished the federal Constitution of 1824 and proclaimed the more centralizing 1835 constitution in its place.

The new laws were unpopular throughout Mexico, leading to violence in several states. War began in Texas on October 2, 1835, with the Battle of Gonzales. Early Texian Army successes at La Bahia and San Antonio were soon met with crushing defeat at the same locations a few months later. The war ended at the Battle of San Jacinto where General Sam Houston led the Texian Army to victory over a portion of the Mexican Army under Santa Anna, who was captured shortly after the battle. The conclusion of the war resulted in the creation of the Republic of Texas in 1836.
