Aristotle related that the revolt of Mytilene against Athens in 428 BCE originated in a dispute over "epikleroi". The Sacred War of 356–346 BCE, between Thebes and Phocis, was also started by a disagreement over "epikleroi". It is likely that Agariste, the daughter of Cleisthenes of Sicyon who married Megacles of Athens, was an "epikleros". Likewise, the widow of the Spartan king Agis IV, Agiatis, was forced to marry Cleomenes, the son of the man who had executed Agis, King Leonidas II. Plutarch stated that the reason Leonidas married Agiatis to Kleomenes was that Agiatis was a "patrouchos" from her father, Gylippos. Another Spartan example may have been Gorgo, the only daughter of King Cleomenes I, who was married to Cleomenes' brother Leonidas I.
