Why did the mexican war of 1846 take place? was the war necessary? was it a good thing? what does this war tell us about this period of american history? was it god's plan that the u. s. extend from the atlantic to the pacific, or were imperialists looking for a way to defend what they planned to do anyway? elaborate?

The war between the U.S and mexico took place because the U.S decide they wanted to expand across the North American continent, which caused them to clash with all of it's neighbors including the british, the Mexicans and the Native Americans. Americans began migrating to the west even into land that did not belong to the United States.When Plok came into Office in 1845, he believed in the idea of "Manifest Destiny" hwich was the belief that expanding the U.S throughout the continents was both lawful and necessary.
