Former President Andrew Jackson, who is credited with saving the United States as a general in the War of 1812, will be replaced on the U.S. $20 bill by Harriet Tubman, an African-American who helped escaped slaves flee the south through the "Underground Railroad" network.
Jackson was a slave owner and the president who forced many thousands of native Americans out of the southeast to make room for white settlers in the "Trail of Tears." Before that, he was commander of the U.S. army that stopped the British invasion of New Orleans during the War of 1812, a feat credited with preserving the United States.
Alexander Hamilton, the first U.S. treasury secretary, will remain on the $10 bill, despite an effort to replace him with a woman. Hamilton's newly-renewed fame as the subject of a smash Broadway musical is credited with saving his currency spot.
