What was the outcome of the war for the United States? What was the outcome of the war for Mexico?

With the end of the War of 1812, the Native Americans could no longer count on Great Britain to shield them from the flood of white settlers headed west. Settlers came in droves by the Erie Canal or through the Cumberland Gap.Although Polk formally relieved his peace envoy, Nicholas Trist, of his post as negotiator, Trist ignored the order and successfully concluded the 1848 Treaty of Guadalupe Hidalgo. It ended the war, and Mexico recognized the Mexican Cession, areas not part of disputed Texas but conquered by the U.S. Army.
