Ephors is a historically accurate title used to describe the upper government within Sparta. At the time of Sparta's creation, there were four departments that were headed by one Ephor and one Deputy Ephor: Foreign Affairs, Defense, Internal Affairs, and Economy. On September 20, 2007 the Department of Education was created, thus creating a 5th Ephor. Also on this date, Sparta changed the government system into having two Ephors for each department who were of equal status, as opposed to one Ephor and one Deputy Ephor.
