Formed as a break-away republic from Mexico by the Texas Revolution, the state claimed borders that encompassed an area that included all of the present U.S. state of Texas, as well as parts of present-day New Mexico, Oklahoma, Kansas, Colorado, and Wyoming based upon the Treaties of Velasco between the newly created Texas Republic and Mexico. The eastern boundary with the United States was defined by the Adams-Onís Treaty between the United States and Spain, in 1819. Its southern and western-most boundary with Mexico was under dispute throughout the existence of the Republic, with Texas claiming that the boundary was the Rio Grande, and Mexico claiming the Nueces River as the boundary. This dispute would later become a trigger for the MexicanAmerican War, after the annexation of Texas.
The Republic of Texas was created from part of the Mexican state Coahuila y Tejas as a result of the Texas Revolution. Mexico was in turmoil as leaders attempted to determine an optimal form of government. In 1835, when President Antonio López de Santa Anna abolished the Constitution of 1824, granting himself enormous powers over the government, wary colonists in Texas began forming Committees of Correspondence and Safety. A central committee in San Felipe de Austin coordinated their activities. In the Mexican interior, several states revolted against the new centralist policies. The Texas Revolution officially began on 2 October 1835, in the Battle of Gonzales. Although the Texians originally fought for the reinstatement of the Constitution of 1824, by 1836 the aim of the war had changed. The Convention of 1836 declared independence on 2 March 1836, and officially formed the Republic of Texas.

Battlefields of Texas – Texas was the site of numerous battles both in its own war for independence from Mexico and in the Civil War.

Maps of the battlefields are also included in this unique collection of Texas history.
Sacrificed at the Alamo: Tragedy and Triumph in the Texas Revolution – The Battle of the Alamo is one of the most compelling stories from American history. Students of the battle often wonder why William B. Travis and his small garrison were left alone to meet their fate at the hands of General Santa Anna. Author Richard B. Winders, the historian and curator at the Alamo, examines events that led to this epic struggle and concludes that in-fighting among the revolutionary leadership doomed the Alamo garrison.

The Texas War of Independence 1835-1836: From Outbreak to the Alamo to San Jacinto – The Texas Revolution is remembered chiefly for the 13-day siege of the Alamo and its immortal heroes.

When the war broke in October 1835, the invading Mexicans, under the leadership of the flamboyant President-General Santa Ana, fully expected to crush a ragged army of frontiersmen.
