Mexican American War

The Mexican American War was a two year long war that
lasted from 1846 to 1848. It was fought between Mexico and
America. The main reason for the war was the then American
President James K. Polk who wanted to spread the boundaries
of America. Although Polk instigated war there were many
other reasons too. It was the first time that America used such
a huge amphibious attack. The war ended with the Treaty of
Guadalupe Hidalgo which was signed on February 2, 1848.
United States had won the war and the 525,000 square miles
of land was signed over to them. These lands include what is
present day California, New Mexico, Arizona, Wyoming,
Colorado, New Mexico and Utah. Mexico also left all rights to
Texas and Rio Grande was recognized as the American
Southern boundary.
