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-American War, or Mexican War, was fought between Mexico and the United States from 1846 to 1848. Mexico has passed the boundary of the United States, has invaded our territory and shed American blood upon American soil. So U.S. President James K. Polk said in his message to Congress in May 1846.
