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.
