With Antigonus and Demetrius now each assuming the title of king, Ptolemy, as well as Cassander, Lysimachus and Seleucus I Nicator, respond by doing the same.
Syria
Antigonus proclaims himself king of Asia Minor and northern Syria thus commencing the Antigonid dynasty. Antigonus appoints Demetrius Poliorcetes king and co-regent.
Sicily
A peace agreement is reached between Syracuse and Carthage. The peace restricts Carthaginian power in Sicily to the area west of the Halycus (Platani) River. This agreement allows the tyrant of Syracuse, Agathocles, to strengthen his rule over the Greek cities of Sicily.
Egypt
Antigonus tries to follow up his victory in Cyprus by invading Egypt with a large army and a formidable fleet. But Ptolemy successfully holds the frontier against him. However, the year's events mean that Ptolemy no longer engages in overseas expeditions against Antigonus.
