Owing to the general lack of Spartan historical records, it is often difficult to be certain which kings reigned during precisely which periods, except when noted by other Greek histories. For the benefit of those interested in the monarchy of Sparta, however, there will here follow two reconstructed lists of kings, those of the Agaid and Eurypontid lines of Dorian Spartans. Because we are here principally concerned with Sparta in the Classical Period and the development that led up to it, the greatly contested kings of Mycenaean Sparta will not be given.
Procles (probably legendary)
Lycurgus (Spartan lawgiver, possibly placed here)
Eucleidas (Agiad usurper)
Eurysthenes (probably legendary)
Acrotatus II (Acrotatus I denied kingship)
Leonidas II (deposed, then returned to kingship)
It is important to note that this list of kings is in no way definitive. Many of the early kings are uncertain, and may even have been legendary, though we will here assume, if only for the sake of convenience, that the kings following Agis I and Eurypon were most likely real historical figures. Further, some of the ancient histories differ on the names of these kings.
