*All of present-day Arizona became part of the Mexican State of Vieja California upon the Mexican assertion of independence from Spain in 1821. The United States took possession of most of Arizona at the end of the Mexican-American War in 1848. In 1853, the land below the Gila River was acquired from Mexico in the Gadsden Purchase. Arizona was administered as part of the Territory of New Mexico until it was organized into a separate territory on February 24, 1863.

Arizona was admitted into the Union—officially becoming a U.S. state—on February 14, 1912." http://en.wikipedia.org/wiki/History_of_Arizona

The State of New Mexico or Estado de Nuevo México is a southwestern state in the United States of America. Over its relatively long history it has also been occupied by Native American populations and has been part of the Spanish viceroyalty of New Spain, a state of Mexico and a U.S. territory. Among U.S. states, New Mexico has simultaneously the highest percentage of Hispanic Americans (some recent immigrants and others descendants of Spanish colonists) and the second-highest percentage of Native Americans (mostly Navajo and Pueblo peoples). As a result, the demographics and culture of the state are unique for their strong Spanish, Mexican, and U.S. Amerindian cultural influences

As a part of New Spain, the claims for the province of New Mexico passed to independent Mexico following the 1810-1821 Mexican War of Independence. During the brief 26 year period of nominal Mexican control, Mexican authority and investment in New Mexico were weak, as their often conflicted government had little time or interest in a New Mexico that had been poor since the Spanish settlements started. Some Mexican officials, saying they were wary of encroachments by the growing United States, and wanting to reward themselves and their friends, began issuing enormous land grants (usually free) to groups of Mexican families as an incentive to populate the province.


Following the Mexican-American War, from 1846-1848 and the Treaty of Guadalupe Hidalgo in 1848, Mexico forcibly ceded its mostly unsettled northern holdings, today known as the American Southwest and California to the United States of America in exchange for an end to hostilities, the evacuation of Mexico City and many other areas under American control. Mexico also received $15 million cash, plus the assumption of slightly more than $3 million in outstanding Mexican debts.

The Congressional Compromise of 1850 halted a bid for statehood under a proposed antislavery constitution. Texas transferred eastern New Mexico to the federal government, settling a lengthy boundary dispute. Under the compromise, the American government established the Territory of New Mexico on September 9, 1850. The territory, which included most of the future states of Arizona, New Mexico, and parts of Colorado, officially established its capital at Santa Fe in 1851.
