This formation changed the course of Greek history, as the Spartans later adopted it and became the dominant military force in Greece. Pheidon then would have been the ruler of Argos during the Second Messenian War, in which Argos supported Messenia to revolt from Sparta's dominance. Throughout his reign, it seems that Argos was in conflict with not only the Spartans, but the Corinthians, as well as the Sicyonians. This may show that he had expansionist policies and achieved some success. It is said that Pheidon held It is possible, though not certain, that the "successful war" that Cleisthenes of Sicyon waged on Argos may have been against his son Lacidamos or grandson, Meltas. Aristotle, in "Politics", claims that he made changes to land reforms “family plots and the number of citizens should be kept equal, even if the citizens had all started with plots of unequal size.” He also claims that Pheidon started off as a king (basileus) and ended up a tyrant (tyrannos). The balance between these two types of ancient 'kingship' seem to have vague boundaries. In the list of the suitors of Agariste, daughter of Cleisthenes of Sicyon, given by Herodotus, there occurs the name of Leokedes or Lakedas, son of Pheidon of Argos. According to this, Pheidon must have flourished during the early part of the 6th century BC. It has therefore been assumed that Herodotus confused two Pheidons, both kings of Argos. The suggested substitution in the text of Pausanias of the 28th for the 8th Olympiad (i.e. 668 instead of 748) would not bring it into agreement with Herodotus, for even then, Pheidon's son could not have been a suitor in 570 for the hand of Agariste.. But the story of Agariste's chronology is questionable. In this story, Herodotus tells about the marriage contest that took place, where the suitor Hippocleides engages in an immodest dance, and thus loses the bride. But this story of Hippocleides may only be a Greek version of the Indian story (jataka) of the "shameless dancing peacock". Thus, the personages may have been introduced regardless of chronology. According to Leslie Kurke, while the marriage of Agariste was indeed historical, the story in question was added and embellished by Herodotus, and modelled on the Indian tale.
