Democracies in Greek city-states were somewhat crude, as women and non-landowners weren't considered citizens and had no say in politics, but they were basically the same systems used in countries like the United States today. Trial by jury was also a Greek idea, changing the system of instant guilt and vigilante justice used by other civilizations of the time.
