Cause → Event → Consequence
After Alexander the Great's death in 323 BC, his empire was nominally ruled by Philip Arrhidaeus and the infant Alexander IV under regent Perdiccas. Dissatisfied satraps, led by Ptolemy I of Egypt, rebelled against Perdiccas, who was subsequently killed by a mutiny within his own camp, creating a leadership vacuum that demanded resolution.
In 321 BC, Alexander's generals convened at Triparadisus to settle the empire's governance. Ptolemy declined the regency, briefly held by Peithon and Arrhidaeus, before Antipater was chosen as the new regent amid opposition from Eurydice, wife of Philip III. The assembly also redistributed the satrapies among the Diadochi.
The Partition of Triparadisus restructured authority across Alexander's former empire, placing Antipater in control as regent and realigning territorial power among the Diadochi. This realignment deepened rivalries among the generals and contributed to the ongoing Wars of the Diadochi that ultimately fragmented the Macedonian empire into separate Hellenistic kingdoms.
Political Outcome
Antipater named regent; satrapies redistributed among Alexander's generals
Perdiccas served as regent under nominal rule of Philip Arrhidaeus and Alexander IV
Antipater appointed regent; satrapies rearranged among the Diadochi
