List of kings of Sparta

This list of kings of Sparta details the important rulers of the Greek city-state of Sparta in the Peloponnesus. Sparta was unusual among Greek city-states in that it maintained its kingship past the Archaic age. It was even more unusual in that it had two kings simultaneously, called Archagetai, coming from two separate lines. According to tradition, the two lines, the Agiads and Eurypontids, were respectively descended from the twins Eurysthenes and Procles, the descendants of Heracles who supposedly conquered Sparta two generations after the Trojan War. The dynasties themselves, however, were named after the twins' grandsons, the kings Agis I and Eurypon, respectively. The Agiad line was regarded as being senior to the Eurypontid line. Although there are lists of the earlier purported Kings of Sparta, there is little evidence for the existence of any kings before the middle of the 6th century BC or so. Spartan kings received a recurring posthumous hero cult like that of the Dorian kings of Cyrene. The kings' firstborns sons, as heirs apparent, were the only Spartan boys expressly exempt from the Agoge, however they were allowed to take part if they so wished, and this endowed them with increased prestige when they ascended the throne.
