When democracy began in Greece, only the inhabitants of the Athenian mother and father could participate, they had to be men and have completed their military service.
After nearly 700 years of this regime, during the war against the Persians, Solon, a politician who ruled Athens, reformed society. All the population participated in the war effort and after the victory, the concept of democracy was redefined, that is, a government made up of Athenian citizens, rich or poor, aristocrats or peasants.
