The Persian Wars
Athens democracy is different from monarchy because monarchy has one king ruling. Democracy had everyone vote. Democracy changed Greece because it either had Monarchy,(a form of government with the king at the head)Oligarchy,(a small group of people having control over a organization or a country)or Tyranny.( If the Greeks don't like who is ruling then they have someone rule by force. For the first time when Greece had changed from their usual government, people controlled and had a say in what the government rules.
