The election of Andrew Jackson dramatically changed the US for several different reasons including:
1) He was an advocate for the "average citizen"- Andrew Jackson was dubbed the "Champion of the Common Man." He received this title because he was not an inherently wealthy man nor was he part of a family that was consistently in politics. Rather, he came from humble beginnings. This story inspired many American citizens.
2) His policies resulted in increased democracy in the US- Jackson helped to get rid of property qualifications and other restrictions to ensure that white farmers had the right to vote, regardless of how much property they owned.
I would guess the Mediterranean Sea.
