Editing Polynices (section)

===Quarrel over the rule of Thebes===
There are several accounts of how Eteocles and Polynices shared the rule after Oedipus' departure from the city. In [[Hellanicus of Lesbos|Hellanicus]]' account, Eteocles offers his brother his choice of either the rule of the city or a share of the property.  In [[Pherecydes of Athens|Pherekydes]], however, Eteocles expels Polynices by force, and keeps the rule of Thebes and the inheritance.   The ''[[Bibliotheca (Pseudo-Apollodorus)|Bibliotheca]]'' and [[Diodorus]] state that the brothers agree to divide the kingship between them, switching each year.  Eteocles, however, was allotted the first year, and refused to surrender the crown.<ref>[[Bibliotheca (Pseudo-Apollodorus)|Apollodorus]], 3.6.1</ref>

Eteocles then has his brother exiled, though Polynices soon finds refuge in the city of [[Argos, Peloponnese|Argos]]. There he is welcomed by the king, [[Adrastus]] who gives him his daughter, [[Argia of Argos|Argia]], for his wife. Polynices then pleads his case to King Adrastus, requesting his help to restore him to the throne of Thebes. Adrastos promises to do so and to that end sets out to gather an expeditionary force to march against Thebes. He appoints seven individual champions to lead this assault, one for each of the seven gates in the walls of the city. Together, these champions, including Adrastus and Polynices, are known as the “[[Seven Against Thebes]]”. The expedition soon proved to be complete disaster, as all of the Argive champions (save for Adrastus) were slain in the ensuing battle; Polynices and Eteocles face off against one another in single combat and kill each other.{{Citation needed|date=September 2022}}

Ten years after Polynices' death, the sons of the seven fallen champions gathered to launch a second assault against the city of Thebes to avenge the deaths of their fathers; they are the known as the [[Epigoni]]. Unlike their fathers before them, these Epigoni are successful in their attempt to take Thebes, after which they install [[Thersander]], Polynices' son by Argia, as the city's new ruler.
