History of Albuquerque, New Mexico
In 1821, Mexico gained its independence from Spain following the Mexican War of Independence. While change was slow to come to the remote province of New Mexico, one major effect was the opening of the region for the first time to American trade. Beginning in the 1820s, the Santa Fe Trail brought American goods and merchants to New Mexico in ever-increasing numbers. Albuquerque's location on the Camino Real also made it a stopover for traders traveling south to the Mexican interior. The Mexican census of 1827 gives a population of 2,547, and shows a more diverse range of occupations than in 1790, including merchants, craftsmen, and a teacher.
History of Mexico
By 1823, Mexicans of all classes were fed up with emperor Agustin de Iturbide's corrupt and oppressive rule. They overthrew him and 4 October 1824, the United Mexican States (Spanish: Estados Unidos Mexicanos) was established. The new constitution was partly modeled on the constitution of the United States. It guaranteed basic human rights and defined Mexico as a representative federal republic, in which responsibilities of government were divided between a central government and a number of smaller units called states. It also defined Catholicism as the official and unique religion. The Federal Republic of Central America was allowed to re-establish its independence, which it had declared on 1 July 1823.
