Mexico ceded California and the New Mexico Territory to the United States as part of the Treaty of Guadalupe Hidalgo in 1848, which ended the Mexican-American War. This treaty resulted in Mexico relinquishing a significant portion of its northern territories, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. The cession significantly expanded U.S. territory and played a crucial role in the nation's westward expansion.
After the war between the US and Mexico was over, Mexico was left defeated and weak. President James K. Polk decided to get these two areas from Mexico in return for 15 million dollars. Later, in the Gadsden Purchase, the US bought present day Arizona and New Mexico.
