Formed as a break-away republic from Mexico by the Texas Revolution, the nation 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 Mexican–American War, after the annexation of Texas.
Texas was not the only Mexican state to secede from Mexico and declare independence. The Mexican states of Coahuila, Nuevo Leon, and Tamaulipas also withdrew themselves from Mexico and formed their own short-lived federal republic called the Republic of the Rio Grande with Laredo as the capital, which is in the present-day State of Texas. The Mexican state of Yucatán also seceded and formed the Republic of Yucatán. Several other states also went into open rebellion including San Luis Potosí, Querétaro, Durango, Guanajuato, Michoacán, Jalisco and Zacatecas.All the Mexican states that revolted, including Texas, were upset with President Antonio López de Santa Anna over abolishing the Mexican Constitution of 1824, dissolving the Mexican Congress and changing the structure of the Mexican government from a federal one to a centralized one. In fact, Yucatán, in its declaration of independence, expressed its desire to re-accede to the Mexican Union if federalism was to be re-established. In fact, Texas was the only seceding Mexican state to retain its independence from Mexico.
However, the context of the Texas rebellion was different from the other Mexican states/provinces attempting to declare independence, because the Texas rebellion was conducted mainly by white American immigrants known as anglos. Mainly because of this fact, Texas was also the only former Mexican state to entertain the idea of joining the United States entirely of its own volition.After gaining their independence, the Texas voters had elected a congress of 14 senators and 29 representatives in September 1836. The Constitution of the Republic of Texas allowed the first president to serve for only two years. It set a three year term for all later presidents.
