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;
Mexican Cession
Considering the seizures, including all of Texas, Mexico lost 54% of its pre-1836 territory in the Treaty of Guadalupe Hidalgo. For only fifteen years from 1821 (when Mexican independence was secured) and the Texan Revolt in 1836, the Mexican Cession (excluding Texas) formed approximately 42% of the country of Mexico; prior to that, it had been a part of the Spanish colony of New Spain for some three centuries. Beginning in the early seventeenth century, a chain of Roman Catholic missions and settlements extended into the New Mexico region, mostly following the course of the Rio Grande from the El Paso area to Santa Fe.
