Events

The Macedonian King, Demetrius Poliorcetes, faces a combined attack from Lysimachus and Phyrrhus, king of Epirus, after Seleucus, Ptolemy and Lysimachus form a coalition to block plans by Demetrius to invade Asia Minor. Ptolemy's fleet appears off Greece, inciting the cities to revolt.
Athens revolts and Demetrius besieges the city. Pyrrhus takes Thessaly and the western half of Macedonia and, with the assistance of Ptolemy's fleet, relieves Athens from Demetrius' siege.
After the Egyptian fleet participates decisively in the liberation of Athens from Macedonian occupation, Ptolemy obtains the protectorate over the League of Islanders, which includes most of the Greek islands in the Aegean Sea. Egypt's maritime supremacy in the Mediterranean in the ensuing decades is based on this alliance.

Following the death of Agathocles, some of his disbanded mercenaries seize Messana in northeast Sicily and set up a society, calling themselves Mamertines (Sons of Mars). The city becomes a base from which they will ravage the Sicilian countryside.

The Sri Maha Bodhi Sacred Fig tree is planted at Anuradhapura, Sri Lanka. This is the earliest known planting date for any planted tree still surviving.
