In the aftermath of the Second War of the Diadochi (315 BC), the aging satrap Antigonus Monophthalmus had been left in undisputed control of the Asian territories of the Macedonian empire (Asia Minor, Syria and the vast eastern satrapies). This left Antigonus in prime position to claim overall rule over the Macedonian empire. Antigonus's growing power alarmed the other major Successors, resulting in the eruption of the Third War of the Diadochi in 314 BC, in which Antigonus faced a coalition of Cassander (ruler of Macedonia), Lysimachus (ruler of Thrace) and Ptolemy (ruler of Egypt). This war ended in a compromise peace in 311 BC, after which Antigonus attacked Seleucus, who was attempting to re-establish himself in the eastern Satrapies of the empire. The resulting Babylonian War lasted from 311 to 309 BC, and resulted in defeat for Antigonus, allowing Seleucus to re-claim the satrapy of Babylonia and overlordship of the territories to the east.
