List Rules American leaders only. Note: "Most important" or "most influential" does not equal "best."

Pioneers who changed the landscape, from the Civil Rights Movement, to Women's Suffrage, to the atom bomb, appear on this list of American leaders who changed the world.

The most important American presidents are ranked here, like Harry S. Truman and George Washington to name a few, along with First Ladies like Eleanor Roosevelt. Industry leaders like Andrew Carnegie and John D. Rockefeller cannot be overlooked, nor can leaders who were not in the U.S. government itself, such as Martin Luther King, Jr. and Susan B. Anthony.
