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;
Treaty of Córdoba
On September 27, 1821, the Army of the Three Guarantees entered triumphantly into Mexico City and on the following day, the Declaration of Independence of the Mexican Empire was widely known. The Spanish Cortes refused to accept the validity of the Plan of Iguala or the Treaty of Córdoba. Spain did not recognize Mexico's independence until December 1836. Therefore, the Mexican Congress elected a Mexican monarch the following year. Iturbide was proclaimed emperor of Mexico on May 18, 1822. The monarchy lasted three years, and after the republican revolution of Casa Mata, the Congress no longer considered the Plan of Iguala or Treaty of Córdoba in effect.
