[11] The name of Nisaea was henceforth confined to only the port-town, while inhabitants of Megara were occasionally called Nisaei to distinguish them from the Megarians of Sicily, their colonists.
[7] The Athenians held Nisaea for a short period of time, but then surrendered it in the Thirty Years' Peace made with Sparta and Spartan allies.
[16] In the first years of the Peloponnesian War (431 BC), Nisaea was defeated in a naval battle against an Athenian fleet.
[7] Following their defeat, eight thousand Peloponnesian soldiers marched to Nisaea, and boarded 40 stolen Magarian ships at the port to attack Athenian strongholds.
[17][3] In the eighth year of the war (424 BC), the long walls which had acted as a Peloponnesian garrison were breached and Nisaea fell to the Athenians after a siege of two days.
[3] The walls of Nisaea which had been damaged during the Peloponnesian war were rebuilt in 343 BC by Athenian army leader Phocion as a symbol of understanding between Megara and Athens.
[8] Megarians produced high quality wool used for clothing and winter attire which was shipped for trade from Nisaea over the Saronic gulf.
[8] An account by Pausanias describes how the roof of the Demeter Malophoros temple had collapsed due to deterioration.
[21] The poet Semonides mentions the port as "the navel of the Nisaians" in another poem about the Persian Wars, which was believed to be written in the 5th century.
[22] The second-century Greek writer Athenaeus preserves a fragment of the lost poem Georgica of Nicander in his The Deipnosophists.
