The Texas Revolution was fought from October 2, 1835 to April 21, 1836 between Mexico and the Tejas portion of the Mexican state of Coahuila y Tejas. Animosity between the Mexican government and the American settlers in Texas began with the Siete Leyes of 1835, when Mexican President and General Antonio López de Santa Anna Pérez de Lebrón abolished the Constitution of 1824 and proclaimed a new anti-federalist constitution in its place. Unrest soon followed throughout all of Mexico and war began in Texas on October 1, 1835 with the Battle of Gonzales. Early Texian success 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 Texas 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. The Republic was never recognized by the government of Mexico, and it teetered between collapse and invasion from Mexico. Texas was annexed by the United States of America in 1845, and it was not until the Mexican–American War of 1846 to 1848 that the "Texan Question" would finally be resolved.
