The war between the United States and Mexico had two basic causes. First, the desire of the U.S. to expand across the North American continent to the Pacific Ocean caused conflict with all of its neighbors; from the British in Canada and Oregon to the Mexicans in the southwest and, of course, with the Native Americans.
The Mexican War officially ended on February 2, 1848 when America and Mexico agreed to the Treaty of Guadalupe Hidalgo. With this treaty, Mexico recognized Texas as independent and the Rio Grande as its southern border. In addition, through the Mexican Cession, America required land that included parts of present-day Arizona, California, New Mexico, Texas, Colorado, Nevada, and Utah.
