The partition is a result of a compromise, essentially brokered by Eumenes, following a conflict of opinion between the party of Meleager, who wishes to give full power to Philip III ( the illegitimate son of King Philip II of Macedon by Philinna of Larissa ), and the party of Perdiccas, who wishes to wait for the birth of the heir of Alexander and his wife, Roxana ( the future Alexander IV ) to give him the throne under the control of a regent.

When Craterus and Antipater, having subdued Greece in the Lamian War, determined to pass into Asia and overthrow the power of Perdiccas, their first blow was aimed at Cappadocia.

After the death of Alexander the Great, Perdiccas expelled the Athenian settlers on Samos to Colophon, on the coast of what is now Turkey.

In return, Perdiccas marches on the Chalcidians, the people he has originally persuaded to revolt.

* Ptolemy executes his deputy, Cleomenes of Naucratis, on the suspicion that Cleomenes favours Perdiccas.

* The Macedonian king, Perdiccas II, once again betrays the Athenians and sends 1000 troops to support a Spartan assault on Acarnania but they arrive too late to help.

* After he frustrates the Athenian attack on Megara, Brasidas marches through Boeotia and Thessaly to Chalcidice at the head of 700 helots and 1000 Peloponnesian mercenaries to join the Macedonian king Perdiccas II.

He flees to Methone in Macedonia, where he is accommodated by King Perdiccas III who draws on his financial expertise.

Ptolemy executed Cleomenes for spying on behalf of Perdiccas — this removed the chief check on his authority, and allowed Ptolemy to obtain the huge sum that Cleomenes had accumulated.

It is said that when Alexander crossed the Hydaspes river on a boat, he was accompanied by Perdiccas, Ptolemy I Soter, Lysimachus and also Seleucus.

After the death of Alexander on June 11, 323 BCE, the city was contested by his successors: Perdiccas, Antigonus Monophthalmus, and Eumenes visited the city, but eventually it became part of the realm of Seleucus I Nicator, of the Seleucid Empire, and capital of a province called Osrhoene ( the Greek rendering of the old name Urhai ).

It is possible that he was closest to Perdiccas, because it was with Perdiccas that he went on the mission to take Peuceolatis and bridge the Indus, and by that time, as Alexander's effective second-in-command, he could doubtless have chosen any officer he cared to name.

After the death of Alexander the Great, Perdiccas expelled the Athenian settlers on Samos to Colophon, including the family of Epicurus, who joined them there after completing his military service.

Perdiccas, who became regent of Macedon on the death of Alexander the Great in 323 BC, had mutineers from the faction of Meleager thrown to the elephants to be crushed in the city of Babylon.

In return, Perdiccas marched on the Chalcidians, the people he had originally persuaded to revolt.

However, Perdiccas once again betrayed the Athenians and sent 1000 troops to support a Spartan assault on Acarnania in 429 but they arrived too late to help ( Thucydides 2. 80 ).

In return for this, the Spartans helped Perdiccas secure his borders, by leading an assault on King Arrhabaeus of Lyncestis, with the promise of support from the Illyrians.

Just four years later, bowing to Athenian pressure, Perdiccas broke with the Peloponnese, and aided Athens in their attack on Amphipolis.

Pausanias killed Philip at the wedding ceremony of Philip's daughter Cleopatra to Alexander I of Epirus, and as he tried to flee to the city gate, tripped on a vine-root and was speared by Attalus ( not Parmenios son-in-law ), Leonnatus, and Perdiccas, who were also bodyguards and friends of Alexander.

Before the reign of Alexander I, father of Perdiccas II, the ancient Macedonians lived mostly on lands adjacent to the Haliakmon, in the far south of the modern region of Macedonia.

Curtius, on the contrary, represents him as breaking out into violent invectives against the ambition of Perdiccas, and abruptly quitting the assembly, in order to excite the soldiery to a tumult.

On the approach of a body of Illyrians, who, though summoned by Perdiccas, unexpectedly declared for Arrhabaeus, the Macedonians fled, and Brasidas's force was rescued from a critical position only by his coolness and ability.

* Leaving Eumenes to hold Asia Minor against Craterus and Antigonus, Perdiccas marches against Ptolemy, but when he fails to cross the Nile he is murdered by mutinous officers.

The empire was put under the authority of a regent in the person of Perdiccas in 323 BC, and the territories were divided between Alexander's generals, who thereby became satraps, at the Partition of Babylon in 323 BC.

* Under the agreement, Philip III becomes king, but Perdiccas, as the regent, effectively becomes the ruler of Alexander's empire.

Perdiccas largely leaves Alexander's arrangements intact:

Although Alexander's brother, Perdiccas III becomes the next king, he is under age, and Ptolemy is appointed regent.

His general Perdiccas became the regent of all of Alexander's empire, while Alexander's physically and mentally disabled half-brother Arrhidaeus was chosen as the next king under the name Philip III of Macedon.

In the " Partition of Babylon " however, Perdiccas effectively divided the enormous Macedonian dominion among Alexander's generals.

To cement his position, Perdiccas tried to marry Alexander's sister Cleopatra.

The First War of the Diadochi began when Perdiccas sent Alexander's corpse to Macedonia for burial.

As part of the division of the provinces after Alexander's death in 323 BC, Antigonus also received Pamphylia and Lycia from Perdiccas, regent of the empire, at the Partition of Babylon.

A conflict exploded between Perdiccas, leader of the cavalry, and Meleager, who commanded the phalanx: the first wanted to wait to see if Roxana, Alexander's pregnant wife, would deliver a male baby, while the second objected that Arrhidaeus was the closest relative living and so should be chosen king.

The smaller ( northern ) region, which had been the sub-satrapy of Matiene, became Media Atropatene under Atropates, the former Achaemenid governor of all Media, who had by then become father-in-law of Perdiccas, regent of Alexander's designated successor.

Initially, Perdiccas ruled the empire as regent for Alexander's half-brother Arrhidaeus, who became Philip III of Macedon, and then as regent for both Philip III and Alexander's infant son Alexander IV of Macedon, who had not been born at the time of his father's death.

Perdiccas appointed Ptolemy, one of Alexander's closest companions, to be satrap of Egypt.

Meleager and the infantry supported the candidacy of Alexander's half-brother, Arrhidaeus, while Perdiccas, the leading cavalry commander, supported waiting until the birth of Alexander's unborn child by Roxana.

In the east, Perdiccas largely left Alexander's arrangements intact – Taxiles and Porus ruled over their kingdoms in India ; Alexander's father-in-law Oxyartes ruled Gandara ; Sibyrtius ruled Arachosia and Gedrosia ; Stasanor ruled Aria and Drangiana ; Philip ruled Bactria and Sogdiana ; Phrataphernes ruled Parthia and Hyrcania ; Peucestas governed Persis ; Tlepolemus had charge over Carmania ; Atropates governed northern Media ; Archon got Babylonia ; and Arcesilas ruled northern Mesopotamia.

Perdiccas ' marriage to Alexander's sister Cleopatra led Antipater, Craterus, Antigonus, and Ptolemy to join together in rebellion.

Meleager and the infantry supported the candidacy of Alexander's half-brother, Arrhidaeus, while Perdiccas, the leading cavalry commander, supported waiting until the birth of Alexander's unborn child by Roxana.
