CHAPTER 6 THE KINGDOM OF MACEDONIA AND THE CHALCIDIC LEAGUE S. Psoma The signifijicance of the Chalcidic League for the Macedonian kingdom is revealed by the alarm of Antigonus Monophthalmus when he heard that Cassander was founding Cassandreia. Diodorus (19.52.2–3) reports that Antigonus accused him of refounding Olynthus. For Antigonus, a contem- porary of Philip II, the League headed by Olynthus was the most signifiji- cant threat to the kingdom in northern Greece. When Philip dissolved the League and destroyed Olynthus, the kingdom was freed from the danger posed by its most powerful neighbour.1 Although Philip II or Alexander III refounded Stageira, one of the league’s cities, at Aristotles’ request, the refoundation of Olynthus was unthinkable for a Macedonian king.2 The Poteidaiatika and the Peloponnesian War The kingdom of Macedonia was responsible both for the creation of the Chalcidic League and for its destruction.3 It was the expansion of the Athenian empire that brought the Macedonian king Perdiccas II and the Chalcidians together. The cities of the Chalcidians were members of the Athenian League, and the Macedonian king, who exported timber to Athens, was an ally of Athens at the beginning of his reign.4 After the 1 The author wishes to thank Edward M. Harris for discussion and advice. The incor- poration of most of the League’s territories into the kingdom was followed by the estab- lishment of Macedonian power in the whole area: see M. B.

The Argead king was not the only power in the area that was hostile to the Athenians. Potidaea, the Corinthian colony on the isth- mus of Pallene, received an ultimatum from Athens, which Thucydides mentions, and a dramatic increase of its phoros, which Thucydides does not mention.7 The cities of the Bottiaeans, whose amount of tribute was increased, also had reason to be hostile to Athens. Finally, the cities of the Chalcidians may have felt threatened by the Athenian decision to send a military colony to the small city of Brea on the Crousis near Olynthus.8 Perdiccas II encouraged the Chalcidians, the Bottiaeans and Potidaea to revolt and promised help in 432 bc. He advised the Chalcidians to abandon their small cities, all situated on the coast, and move to Olyn- thus. The Chalcidians of Thrace, who had arrived from Euboea before the creation of the polis, lived in small urban settlements in Sithonia and at the foot of the Toronean gulf.9 In 479 bc, they were granted Olynthus, a former Bottiaean city, by the Persians. By abandoning their small cities and moving to Olynthus, they could avoid the immediate threat from the Athenian fleet.10 Perdiccas II granted them land around Lake Bolbe where they founded Apollonia.11 As a result of the simultaneous abandonment of 5 For literary sources and discussion see E.
