* Ptolemy tries to occupy Syria. However, Demetrius Poliorcetes wins a battle over Ptolemy's forces and Antigonus enters Syria in force. So, after only a few months, Ptolemy evacuates his forces from Syria.
* In view of the threat by Seleucus to his control of the East, Antigonus decides to make peace with all of his adversaries, except Seleucus, who now holds Babylon. All of the diadochi confirm the existing boundaries and the freedom of the Greek cities. Ptolemy and Lysimachus are confirmed as satraps of Egypt and Thrace, respectively, and Antigonus and Cassander are confirmed as commanders of the army in Asia and Europe. Antigonus, no longer regent but now titled the strategos (officer in charge) of the whole of Asia, rules in Syria from the Hellespont to the Euphrates, including Asia Minor.
* It is agreed by all parties that the young king Alexander IV of Macedon, son of Alexander the Great, will become king of the whole empire when he comes of age in six years' time.
