History of Hispanic and Latino Americans in the United States
In 1821, Mexico gained independence from Spain, annexing the southwest of the present United States, including Arizona. As missions began to wither, Mexico began auctioning off more land, causing the Pimería Alta and the Apachería to shrink as territory expanded. In the meantime, American mountain men began to enter the region, looking to trap beavers for their pelts. In 1836, Texas declared independence from Mexico and claimed much of the territory in the northern lands of Mexico. When the United States annexed Texas in 1846 over the strong objections of the Mexican government, U.S. troops moved into disputed territory. The hostilities erupted in the Mexican–American War (1846–1848). The U.S. occupied Mexico City and forced the newly founded Mexican Republic to give up its northern half, including the later Arizona.
Celebration of Mexican political anniversaries in 2010
In 2010, Mexico celebrated both the 200th anniversary of its Independence and 100th anniversary of its Revolution. The entire year was proclaimed by President Felipe Calderón as "Año de la Patria", or "Year of the Nation." 16 September 1810 is the day of the "Grito de Dolores" or Miguel Hidalgo's call to take up arms against the Spanish colonial government. The start of the Mexican Revolution is celebrated as being 20 November 1910, when Francisco "Pancho" Villa and Pascual Orozco led the first insurrectionist attack. Events and other promotions of these celebrations were designed to link of Mexico's identity and historic continuity. During a speech at the inauguration of the Casa de Allende (Allende House) Historic Museum, Felipe Calderón called upon Mexico to use the upcoming anniversaries to reflect on where the country has been and to think about what kind of Mexico descendants will inherit in the future. He said the vision of the insurgents of the War of Independence was forward, not backward, so every celebration of these past events must consider the future as well.
