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.
Guerrero
Peoples of the territory of Guerrero immediately supported the cause of Miguel Hidalgo y Costilla which would culminate with the Independence of Mexico. During the first part of the Mexican War of Independence, José María Morelos fought on the side of Miguel Hidalgo in the southern part of Mexico, including the Acapulco area and the Costa Grande. However, the insurgents were never able to take the port. They were able to take control of territories in the center of the state. Morelos took Chilpancingo and set up the Congress of Anáhuac, which would publish the document "Sentimentos de la Nación" on 6 November 1813. The Congress of Anáhuac also approved the Act of Independence written by Carlos María Bustamante. Later, the Mexican flag was designed and first sewn in Iguala, after Agustín de Iturbide and Vicente Guerrero joined forces under the Plan of Iguala to end the war in 1821.
