First a little history: The United States has been the home of those with Mexican descent since the Battle of Gonzales. Settlers from the United States were called into Mexico by the Mexican government to provide help needed to counter Indian raids from across the border

The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna reclaimed the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States), killing the Texian and immigrant occupiers.

Santa Anna’s cruelty during the battle inspired many Texians, both legal Texas settlers and illegal immigrants from the United States, to join the Texian Army. Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the rebellion.

The Battle of Gonzales was the first military engagement of the Texas Revolution. It was fought near Gonzales, Texas, on October 2, 1835, between rebellious Texian settlers and a detachment of Mexican army soldiers. Gonzales became a rallying point for Texians opposed to GeneralAntonio López de Santa Anna‘s policies.On October 11, the Texians unanimously elected  Stephen F. Austin their commander, despite his lack of military training. By the end of the year, the Texians had driven all Mexican troops from Texas. COME AND TAKE IT WAS THE BATTLE CRY

The U.S.–Mexican War or the Invasion of Mexico, was an armed conflict between the United States of America and the United Mexican States from 1846 to 1848. It followed in the wake of the 1845 U.S. annexation of Texas, which Mexico considered part of its territory in spite of its de facto secession in the 1836 Texas Revolution.

Santa Anna defeated the Texians at the Alamo but he was defeated by the Texian Army commanded by General Sam Houston and captured at the Battle of San Jacinto and signed a treaty recognizing Texas’ independence.

The 1848 Treaty of Guadalupe Hidalgo ended the war and specified its major consequence: the Mexican Cession of the territories of Alta California and Santa Fe de Nuevo México to the United States. The U.S. agreed to pay $15 million compensation for the physical damage of war. In addition, the United States assumed $3.25 million of debt owed by the Mexican government to U.S. citizens. Mexico acknowledged the loss of Texas and thereafter cited the Rio Grande as its national border with the United States. Texas became the 29th state in 1845.

In the aftermath of Texas becoming a state. First of all the Mexican governments following the Treaty of Guadalupe Hidalgo never fully accepted the loss of Texas to the Gringo. Many words have been exchanged through the years.
