Mythical homeland of the Aztec civilization.

Used in the Mexican-American community to refer to the land ceded by Mexico to the United States in the 1848 Treaty of Guadalupe Hidalgo: California, Arizona, New Mexico, Texas, and parts of Utah, Nevada, and Colorado.

The Chicano movement's use of Atzlan as a symbol serves to reject a language-based identity (with labels such as "Hispanic" or "Latino") and claim identity based on land, indigenous culture, and race ("La Raza").
