Arizona is home to many Indian cultures such as the Apache and the
Navajo. Arizona has the largest Native American population of any
state. More than 14 tribes are represented on 20 reservations,
including part of the Navajo Nation, which is located in the Four
Corners region of Arizona, Colorado, New Mexico, and Utah.

Spanish treasure seekers from Mexico arrived in the area in the 16th
century, thus establishing Mexico's claim to the area. The area was
ruled by Spain until Mexico won its independence in 1821. Mexico
ceded the territory to the United States as part of New Mexico during
the Mexican-American War of 1848. The Gadsden Purchase, an area south
of the Gila River, was added in 1853. Arizona was organized as a
territory in 1863 and became the 48th state in 1912.
