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.
Centralist Republic of Mexico
Months later, Antonio López de Santa Anna, in response to the declaration of independence, threatened to send in the troops if it was not reversed while also assuring the Tabasco authorities that Federalism would soon be reinstated. This combined threat and promise culminated in the reinstatement of Tabasco into the Mexican Republic on December 2, 1842. But four years later, Tabasco again declared its independence in November 1846 as a protest to the lack of Central government assistance in resisting the American occupation of its coast earlier that same year.
