§1.12.1ἐπεὶ καὶ μετὰ τὰ Τρωικὰ ἡ Ἑλλὰς ἔτι μετανίστατό τε καὶ κατῳκίζετο, ὥστε μὴ ἡσυχάσασαν αὐξηθῆναι.
For even after the Trojan war, Greece was still subject to migrations and resettlement, so that she could not grow through lack of tranquility.
§1.12.2ἥ τε γὰρ ἀναχώρησις τῶν Ἑλλήνων ἐξ Ἰλίου χρονία γενομένη πολλὰ ἐνεόχμωσε, καὶ στάσεις ἐν ταῖς πόλεσιν ὡς ἐπὶ πολὺ ἐγίγνοντο, ἀφ’ ὧν ἐκπίπτοντες τὰς πόλεις ἔκτιζον.
Indeed, the return of the Greeks from Ilium, being long delayed, caused many innovations, and factions arose in the cities for the most part, being expelled from which they founded [new] cities.
§1.12.3Βοιωτοί τε γὰρ οἱ νῦν ἑξηκοστῷ ἔτει μετὰ Ἰλίου ἅλωσιν ἐξ Ἄρνης ἀναστάντες ὑπὸ Θεσσαλῶν τὴν νῦν μὲν Βοιωτίαν, πρότερον δὲ Καδμηίδα γῆν καλουμένην ᾤκισαν (ἦν δὲ αὐτῶν καὶ ἀποδασμὸς πρότερον ἐν τῇ γῇ ταύτῃ, ἀφ’ ὧν καὶ ἐς Ἴλιον ἐστράτευσαν), Δωριῆς τε ὀγδοηκοστῷ ἔτει ξὺν Ἡρακλείδαις Πελοπόννησον ἔσχον.
For the Boeotians of today, having been driven from Arne by the Thessalians in the sixtieth year after the capture of Ilium, settled the country now called Boeotia, but formerly the Cadmeian land (though there had also been a portion of them in this land previously, from whom indeed they marched against Ilium); and the Dorians in the eightieth year with the Heraclidae occupied the Peloponnese.
§1.12.4μόλις τε ἐν πολλῷ χρόνῳ ἡσυχάσασα ἡ Ἑλλὰς βεβαίως καὶ οὐκέτι ἀνισταμένη ἀποικίας ἐξέπεμψε, καὶ Ἴωνας μὲν Ἀθηναῖοι καὶ νησιωτῶν τοὺς πολλοὺς ᾤκισαν, Ἰταλίας δὲ καὶ Σικελίας τὸ πλεῖστον Πελοποννήσιοι τῆς τε ἄλλης Ἑλλάδος ἔστιν ἃ χωρία.
And at last, after a long time, Greece, having become securely tranquil and being no longer subject to displacement, sent out colonies; the Athenians colonized the Ionians and most of the islanders, while the Peloponnesians colonized the greater part of Italy and Sicily, and certain places in the rest of Greece.
πάντα δὲ ταῦτα ὕστερον τῶν Τρωικῶν ἐκτίσθη.
All these were founded after the Trojan war.
