Although most people don't know much about James Polk, many historians think he was one of the better U.S. presidents. Polk did something not many presidents have done. He made a list of things he promised to do and then actually did all of them President Polk lowered tariffs--taxes on imported goods. He also took the nation's money out of different banks and put it into a national treasury so it would be better protected. Finally, he added more land to the U.S.--1 million square miles--than any other president.
