Nominally King of Babylonia and Macedonia (323-316). Son of Phillipe II of Macedon and half-brother of Alexander the Great, his birth name was Arrhidaeus. Unfit to rule, he was recognized as the successor of Alexander under the regency of Perdiccas until the aftermath of the Third Diadochi War. He is attested in several cuneiform sources including the Hellenistic King List, and the Uruk King List.
