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.
Coahuila y Tejas
From the time Mexico became independent from Spain, there was public support for abolishing slavery. Fears of an economic crisis if all of the slaves were simultaneously freed led to a gradual emancipation policy. In 1823, Mexico forbade the sale or purchase of slaves, and required that the children of slaves be freed when they reached fourteen. Any slave introduced into Mexico by purchase or trade would also be freed. Many of the colonists in Texas, however, had already owned slaves and brought them to the new territory when they immigrated from the United States.
