Hispanics and Latinos in New Mexico
The mainland part of New Spain won independence from Spain in 1821 and New Mexico became part of the new nation of Mexico. After independence from Spain, the Spanish population began to mix somewhat with the indigenous populations. The new 'Mexican' élite attempted to create a common identity out of all the classes and different ethnicities. Nationalists attempted to establish equality, if only legally, between these different groups. The Spanish settlers of New Mexico and their descendants adapted to Mexican citizenship somewhat. In 1836, after the Republic of Texas gained independence, Texas claimed part of the Province of New Mexico, which was disputed by Mexico. In 1841, the Texians sent an expedition to occupy the area, but the expedition was captured by Mexican troops;

In 1834, General Antonio López de Santa Anna became the centralist dictator of Mexico, abandoning the federal system. He decided to quash the semi-independence of Texas, having succeeded in doing so in Coahuila (in 1824, Mexico had merged Texas and Coahuila into the enormous state of Coahuila y Tejas). Finally, Stephen F. Austin called Texians to arms, and they declared independence from Mexico in 1836. After Santa Anna defeated the Texians in the Battle of the Alamo, he was defeated by the Texian Army commanded by General Sam Houston and captured at the Battle of San Jacinto; he signed a treaty recognizing the independence of Texas.
