In the year 423 BCE, the Athenians and Spartans, who had been in the midst of the Peloponnesian War since 431 BCE, decided to observe an armistice that was planned to last for one year. Athens and Sparta did, indeed, halt the official war, yet smaller states on the periphery of their alliances kept fighting in their own minor feuds. As for the leaders of the war, Athens and Sparta, they also kept up their militancy in ways that would not break the armistice. For Athens, this was a time to crush rebellions and suppress dissidents. On the Peloponnesian side, a general named Brasidas (responsible for many of the aforementioned Athenian rebellions) decided to occupy his time by participating in a joint-invasion alongside his ally, King Perdiccas of Macedonia, against the Kingdom of Lyncus.
