New Mexico is a state in the Southwestern region of the United States. It is one of the Mountain States of the southern Rocky Mountains, sharing the Four Corners region with Utah, Colorado, and Arizona. It also borders the state of Texas to the east and southeast, Oklahoma to the northeast, and shares an international border with the Mexican states of Chihuahua and Sonora to the south. New Mexico's largest city is Albuquerque, and its state capital is Santa Fe, the oldest state capital in the U.S., founded in 1610 as the government seat of Nuevo México in New Spain.
Since Arizona became a U.S. state in 1912, it has sent congressional delegations to the United States Senate and United States House of Representatives, beginning with the 63rd United States Congress in 1913. Before becoming a state, the Arizona Territory elected a non-voting delegate at-large to Congress from 1864 to 1912. Each state elects two senators to serve for six years, and varying numbers of members of the House, depending on state population, to two-year terms. Arizona has sent nine members to the House in each delegation since the 2010 United States Census.

The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that includes Arizona and New Mexico, along with adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Before 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854.
The Western United States is one of the four census regions defined by the United States Census Bureau.
The Territory of New Mexico was an organized incorporated territory of the United States from September 9, 1850, until January 6, 1912. It was created from the U.S. provisional government of New Mexico, as a result of Nuevo México becoming part of the American frontier after the Treaty of Guadalupe Hidalgo. It existed with varying boundaries until the territory was admitted to the Union as the U.S. state of New Mexico in 1912. This jurisdiction was an organized, incorporated territory of the US for nearly 62 years, the longest period of any territory in the contiguous United States.
The Territory of Arizona, commonly known as the Arizona Territory, was a territory of the United States that existed from February 24, 1863, until February 14, 1912, when the remaining extent of the territory was admitted to the Union as the state of Arizona. It was created from the western half of the New Mexico Territory during the American Civil War.
The territory of the United States and its overseas possessions has evolved over time, from the colonial era to the present day. It includes formally organized territories, proposed and failed states, unrecognized breakaway states, international and interstate purchases, cessions, and land grants, and historical military departments and administrative districts. The last section lists informal regions from American vernacular geography known by popular nicknames and linked by geographical, cultural, or economic similarities, some of which are still in use today.
The Californias, occasionally known as the Three Californias or the Two Californias, are a region of North America spanning the United States and Mexico, consisting of the U.S. state of California and the Mexican states of Baja California and Baja California Sur. Historically, the term Californias was used to define the vast northwestern region of Spanish America, as the Province of the Californias, and later as a collective term for Alta California and the Baja California peninsula.
The El Paso and Southwestern Railroad began in 1888 as the Arizona and South Eastern Railroad, a short line serving copper mines in southern Arizona. Over the next few decades, it grew into a 1200-mile system that stretched from Tucumcari, New Mexico, southward to El Paso, Texas, and westward to Tucson, Arizona, with several branch lines, including one to Nacozari, Mexico. The railroad was bought by the Southern Pacific Railroad in 1924 and fully merged into its parent company in 1955. The EP&SW was a major link in the transcontinental route of the Golden State Limited.

Its capital and largest city is Phoenix, which is the most populous state capital in the United States.
