Passage 2.13.1
Ἡρακλειδῶν δὲ κατελθόντων Πελοπόννησος ἐταράχθη πᾶσα πλὴν Ἀρκάδων, ὡς πολλὰς μὲν τῶν πόλεων συνοίκους ἐκ τοῦ Δωρικοῦ προσλαβεῖν, πλείονας δὲ ἔτι γενέσθαι τὰς μεταβολὰς τοῖς οἰκήτορσι. τὰ δὲ κατὰ Φλιοῦντα οὕτως ἔχει. Ῥηγνίδας ἐπʼ αὐτὴν ὁ Φάλκου τοῦ Τημένου Δωριεὺς ἐκ τε Ἄργους στρατεύει καὶ ἐκ τῆς Σικυωνίας. τῶν δὲ Φλιασίων τοῖς μὲν ἃ προεκαλεῖτο Ῥηγνίδας ἐφαίνετο ἀρεστά, μένοντας ἐπὶ τοῖς αὑτῶν βασιλέα Ῥηγνίδαν καὶ τοὺς σὺν ἐκείνῳ Δωριεῖς ἐπὶ ἀναδασμῷ γῆς δέχεσθαι·
When the Heracleidae returned, the whole Peloponnese was thrown into confusion, apart from Arcadia. Many cities encountered newcomers who settled among them as a result of the Dorian migration, and yet even greater changes befell the inhabitants. The events concerning Phlius took place as follows: Rhegnidas, the son of Phalces, a Dorian from Temenus' family, marched against the city from Argos and Sicyonia. Among the Phliasians, some approved of the proposals Rhegnidas brought forward, choosing to remain in possession of their own lands and thus admitting Rhegnidas and the Dorians who accompanied him on terms of a redistribution of territory.
