# Perdiccas

Perdiccas (Greek: Περδίκκας, Perdikkas; c. 355 BC – 321/320 BC) was a Macedonian general, successor of Alexander the Great, and regent of Alexander's empire after his death. When Alexander was dying, he entrusted his signet ring to Perdiccas. Initially the most pre-eminent of the successors, Perdiccas effectively ruled Alexander's increasingly unstable empire from Babylon for three years, until his assassination, as the kings he ruled for were incapable.
Perdiccas was born to Macedonian nobility. A supporter, somatophylax (bodyguard) and hetairos (elite cavalry commander) of Alexander, he took part in Alexander's campaign against the Achaemenid Persian Empire, distinguishing himself in Thebes and Gaugamela, and followed Alexander into India. When Alexander died in 323 BC, Perdiccas rose to become supreme commander of the imperial army, as well as regent for Alexander's vast empire, ruling on behalf of Alexander's intellectually disabled heir, King Philip III Arrhidaeus and his infant son, King Alexander IV of Macedon.
Perdiccas gained supreme power but also inherited the problems of Alexander's quickly conquered and unstable empire. To consolidate power and retain authority, Perdiccas crushed numerous revolts, like that of Ariarathes, and assassinated rivals, like Meleager. Perdiccas' position as regent was never fully secure, however, and his authority was repeatedly contested by other generals. His attempt to marry Cleopatra of Macedon, Alexander's sister, which would have given him claim to the Macedonian throne, angered critical generals—including Antipater, Craterus and Antigonus—who decided to revolt against the regent in the First War of the Diadochi. In response to this formidable coalition and a provocation from another general, Ptolemy, Perdiccas invaded Egypt, but his soldiers mutinied and killed him in 321/320 BC when the invasion foundered.

## Family background and early life

According to the 2nd-century historian Arrian, Perdiccas was the son of the Macedonian nobleman, Orontes, a descendant of the independent princes of the Macedonian province of Orestis. While Perdiccas' actual date of birth is unknown, he would seem to have been of a similar age to Alexander. He had a brother called Alcetas and a sister, Atalante, who married Attalus. Perdiccas may have had, through some distant relation, blood of the Argead royal family.
Little is known of Perdiccas' youth, but he was probably brought to the Macedonian court in Pella to serve as page like many other young nobles alongside Alexander. When Pausanias assassinated King Philip II of Macedon in 336 BC, Alexander the Great's father, Perdiccas was among those who chased the assassin down and killed him.
An anecdote reports that Perdiccas once went into the cave of a lioness who had recently gave birth, and stole two of its cubs. Another tells a story of his fondness for exercise, along with his fellow Orestian and successor, Craterus.

## Career under Alexander

As the commander of a battalion of the Macedonian phalanx (heavy infantry), in 335 BC Perdiccas fought in the Balkan campaigns of Alexander against the Illyrian peoples located northwest of Macedon. In the same year, he distinguished himself during the conquest of Thebes, which had rebelled against Macedon following the death of Philip II. Perdiccas led a contingent which stormed the rear gate of the city, and was heavily wounded during the fighting.
Afterward, Perdiccas accompanied Alexander on his campaigns against the Achaemenid Persian Empire. Sources generally agree that Perdiccas was a loyal soldier of Alexander. For example, the ancient historian Plutarch reports the following conversation between the two prior to the Battle of Granicus (the first encounter between Alexander and the Persians), when Alexander was allotting out lands and properties to his followers:
   So that at last [Alexander] had portioned out or engaged almost all the royal property; which giving Perdiccas an occasion to ask him what he would leave himself, he replied, his hopes. "Your soldiers," replied Perdiccas, "will be your partners in those," and refused to accept of the estate he had assigned him. Some others of his friends did the like...
Perdiccas led his battalion at the battles of Granicus, Issus, and Gaugamela, where he again distinguished himself and was wounded. Perdiccas became somatophylax ('bodyguard') of Alexander following this, and his influence probably grew steadily thereafter. Perdiccas' battalion was used by Alexander to flank and win the Battle of the Persian Gate in 330 BC. When Philotas, the son of Parmenion and an important general in Alexander's army, was held in suspicion by the king, Perdiccas was among the close companions who joined Alexander in discussing what should be done. When Alexander attempted to kill another of his companions, Cleitus the Black, in 328 BC, Perdiccas was among those who held Alexander back.
Subsequently, he held an important command in the Indian campaigns of Alexander. Perdiccas and Hephaestion, Alexander's closest companion, were generally compatible and seemed to have got along well, as both were selected to ford the Indus River (a task which required coordination) by Alexander and did so without issue. This contrasts Hephaestion's known quarrels with other prominent generals of Alexander, such as Craterus and Eumenes of Cardia. Perdiccas was part of the cavalry under Alexander's control at the Battle of the Hydaspes in 326 BC and crossed the river with him in said battle. Perdiccas later plundered around Sangala, and assaulted and sacked the Mallian towns. Alexander was wounded in this campaign, having been shot in the chest with an arrow that penetrated his armor; some traditions say Perdiccas was the one who cut the arrow out with a sword and saved the king's life.
In 324 BC, at the nuptials celebrated at Susa, a prominent Persian city, Perdiccas married the daughter of the Persian satrap of Media, Atropates. Perdiccas' wife's name is not known and he likely divorced her following Alexander's death. When Hephaestion unexpectedly died the same year, Perdiccas was appointed his successor as commander of the Companion cavalry and chiliarch, effectively becoming Alexander's second-in-command. He was also entrusted with the responsibility of transferring Hephaestion's corpse to Babylon for burning and burial. As Alexander lay dying in his bed, he gave his signet ring to Perdiccas. Although Alexander's intention with this action is not clear, it is probable that he wanted Perdiccas to reign as regent until his children came of age.

## Succession and crisis

Following the death of Alexander the Great on 11 June 323 BC in Babylon, his generals met to discuss their next steps. Perdiccas was very influential at this point, as a close friend of Alexander, his second-in-command, and possessing the signet ring Alexander gave him.

### Debate for leadership

The debate around who would succeed Alexander led to a divide in the Macedonian army; on one side were the aristocratic cavalry officers (generals), and on the other side the infantry soldiers. The infantry, also wanting to listen to the discussion, broke into the room where Perdiccas and the other generals were speaking.
Perdiccas, having placed the ring he received from Alexander on the throne, along with the royal robes and diadem, proposed that a final decision wait until Alexander's wife Roxana, who was pregnant, had given birth; if the unborn child (the future Alexander IV of Macedon) was a boy, then Perdiccas proposed that the child be chosen as the new king. The Roman historian Quintus Curtius Rufus provides Perdiccas' apparent speech to the assembly:
   For my part, I return to you the ring handed to me by Alexander, the seal of which he would use on documents as symbol of his royal and imperial authority. The anger of the gods can devise no tragedy to equal this with which we have been afflicted; and yet, considering the greatness of Alexander's achievements, one could believe that such a great man was merely on loan from the gods to the world so that, when his duty to it was complete, they might swiftly reclaim him for their family. Accordingly, since nothing remains of him apart from the material which is excluded from immortality, let us perform the due ceremonies to his corpse and his name, bearing in mind that the city we are in, the people we are among and the qualities of the leader and king of whom we have been deprived. Comrades, we must discuss and consider how we can maintain the victory we have won among the people over whom we have won it. We need a leader; whether it should be one man or more is up to you. But you must realize this: a military unit without a chief is a body without a soul. This is the sixth month of Roxana's pregnancy. We pray that she has produced a male who, with the gods' approval, will assume the throne when he comes of age. Meanwhile, designate those you want as your leaders.
This meant that Perdiccas would be the regent and effectively the ruler of Alexander's empire until Roxana's unborn child was old enough to rule. Though his later actions would show Perdiccas had ambitions to be king, during the assembly, when Aristonous, a fellow bodyguard, proclaimed Perdiccas should be made king and the suggestion was met with approval, Perdiccas hesitated to accept the position. Another of Alexander's companions, Ptolemy, proposed a joint board of generals to rule the Empire, perhaps as a slight against Perdiccas as such a scheme would greatly decrease his current authority. Other proposals were considered, but despite misgivings amongst the other generals, most accepted Perdiccas' proposal of waiting until Roxana gave birth. The agreed upon interim arrangement was Perdiccas and Leonnatus overseeing Asia, and Craterus and Antipater ruling Macedonian-controlled Europe.
However, the infantry commander, Meleager, disagreed with Perdiccas' plans. Meleager argued in favour of Alexander's intellectually disabled half brother, Philip III Arrhidaeus, whom he considered first in succession. The infantry supported this proposal with Meleager's troops willing to fight in favour of Philip III, who they crowned. The infantry began to riot, and the generals united under Perdiccas' authority. After a brief scuffle, Perdiccas ordered a tactical retreat and the generals fled Babylon, but Perdiccas remained for a time hoping to regain the allegiance of the infantry. Meleager sent assassins to kill him. Despite only having page boys with him, Perdiccas met the assassins openly, and taunted and terrified them into fleeing.

### Siege of Babylon

Perdiccas joined the generals outside of Babylon and put the city to siege, cutting off the supply lines. Meleager's powerbase began to diminish, and he was eventually convinced by Eumenes of Cardia, Alexander's former secretary, to reconcile with the generals, perhaps in collusion with Perdiccas. Perdiccas announced Philip III and the unborn child of Alexander's wife Roxana (the future Alexander IV of Macedon) would be recognized as joint kings to placate Meleager. While the general Craterus was officially declared "Guardian of the Royal Family", Perdiccas effectively held this position, as the joint kings were with him in Babylon. Antipater was confirmed as viceroy of Macedon and Greece. To formalize the reconciliation between the generals and infantry, Perdiccas announced a lustration (a religious purification ritual) and review of the army, convincing Meleager and the infantry to attend.
When the infantry accepted and marched outside Babylon, Perdiccas held a clear military advantage as he controlled all the cavalry and could threaten the infantry with a flanking maneuver. He then sent Philip III to order the capture the rebellious leaders of the infantry, except for Meleager. Perdiccas had these 300 men killed by trampling from his war elephants. Soon afterward, having cowed the infantry, Perdiccas had Meleager executed as well. Though successful in resecuring his power, the incident left the chiliarch and regent Perdiccas untrusting of the other generals, who were now also suspicious of him.

## Regent of Alexander's empire

Through the Partition of Babylon in 323 BC, a compromise was reached under which Perdiccas was to serve as "Regent of the Empire" (epimelētēs) for the disabled Philip III and infant Alexander IV, as well as supreme commander (strategos) of the imperial army. Perdiccas soon showed himself intolerant of any rivals and, acting in the name of the two kings, sought to hold the empire together under his own hand. Perdiccas oversaw the distribution of satrapies to the other generals, sending away officers who threatened his authority. Perdiccas also attached Cleomenes of Naucratis to Ptolemy in Egypt as a lieutenant. Modern historians believe this was done to limit Ptolemy's power and keep watch on his actions.
The men who remained at court with Perdiccas were probably those he could trust: his brother Alcetas, his brother-in-law Attalus, Seleucus, and Aristonous. Alexander the Great's second wife, Stateira, was murdered by Perdiccas, possibly at the urging of Roxana. Perdiccas also procured Alexander's "Last Plans" through the help of Eumenes, read the plans out before the army, and rejected them. This was done because not only were the plans extraordinarily expensive and grand (they included, for example, conquest of all of North Africa and the powerful Carthaginian Empire, along with the construction of a fleet of a thousand warships), but also because Perdiccas probably did not want to anger Antipater by replacing him with Craterus. Alexander's wife Roxana gave birth (in the late summer or early fall of 323 BC) and Perdiccas took guardianship over Alexander IV.

### Rebellions and refusals

As his authority was unstable, possibly as early as the Siege of Babylon Perdiccas had negotiated marriage with Nicaea of Macedon, the daughter of Antipater, to ally himself with the viceroy, acknowledging Antipater's rule in Europe while improving his own position in Asia.

#### Bactrian Greek revolt

During the winter of 323 BC in the Upper Satrapies, specifically in Bactria (in modern-day Afghanistan), a rebellion had begun consisting of 23,000 Greek mercenaries who had heard of Alexander's death and now wanted to return home. In response, Perdiccas tasked Peithon, another of Alexander's somatophylakes and satrap of Media, with quelling it, and sent orders for the eastern satraps to contribute troops as well. Peithon marched east leading 3,800 men, with 10,000 to come from the eastern satraps. Although ancient sources suggest Peithon intended to recruit the Greeks and betray Perdiccas, modern historians dispute this. When the armies met, the Greeks surrendered and were partially slaughtered by Peithon's army. Perdiccas' motive in this affair is not clear; some traditions say he gave the order for the massacre in order to ensure Peithon did not gain an army or to punish the rebels, while another hypothesis is that the slaughter of the Greeks may have occurred through the actions of Peithon and then, later, was blamed on Perdiccas.

#### Conquest of Cappadocia

Despite success in the east, Perdiccas' authority as regent was then challenged in the west. Here, Perdiccas had appointed Leonnatus, another somatophylax, as satrap of Hellespontine Phrygia on the western coast of Asia Minor. At the Partition of Babylon, Perdiccas' supporter Eumenes was given the satrapies of Cappadocia and Paphlagonia, but both were unconquered. Perdiccas thus used his authority as regent of the joint kings to order Leonnatus and Antigonus (satrap of Phrygia, Pamphylia and Lycia) to aid Eumenes in securing his satrapy. Perdiccas probably gave Eumenes 5000 talents of gold for the reconquest of Cappadocia, allowing Eumenes to hire mercenaries.
Antigonus refused Perdiccas' order. Leonnatus accepted, mustering an army and marching to Cappadocia, arriving in the spring of 322 BC. Leonnatus, however, received a letter from Macedon from Cleopatra, Alexander the Great's full sister, and Antipater, both asking him to come west – Cleopatra (probably influenced by her mother Olympias) offered herself as Leonnatus' bride (which would give Leonnatus claim to the Macedonian throne), while Antipater, who was besieged at Lamia as part of the Lamian War, asked Leonnatus for urgent assistance. Leonnatus told Eumenes of his plan to head west, attempting to convince him to join him; Eumenes refused and departed to Perdiccas' court, informing him of Leonnatus' intentions. For this information, Perdiccas elevated Eumenes to the ruling council of the Empire. This incident may have been what made Perdiccas "regard Cleopatra as a means of gaining supreme power".
Upon learning of this, in the early summer of 322 BC Perdiccas marched the imperial army towards Asia Minor to reassert his dominance as regent, install Eumenes in Cappadocia, and confront Antigonus. It also allowed him to "complete the conquest of Alexander's empire" as Alexander had ignored Cappadocia. In a single campaigning season, Perdiccas defeated Ariarathes I and his large army (30,000 infantry, 15,000 cavalry) in two decisive pitched battles, capturing more than 5,000 soldiers and killing 4,000 others, allowing his supporter Eumenes to claim his satrapy. This greatly contributed to Perdiccas' prestige; Perdiccas took Ariarathes captive, tortured and killed him, and apparently impaled most of his family. Perdiccas ordered Leonnatus to appear before him to stand trial for disobedience, but Leonnatus died during the Lamian War before the order reached him. At some time during the first year of his reign, Perdiccas crowned Alexander IV, Roxana and Alexander's child, as king alongside Philip III.

#### Conquest of Pisidia, Isauria, Larandia

Having settled Cappadocia, Perdiccas planned to send Eumenes to subdue the Satrapy of Armenia, which was being mismanaged by Neoptolemus. He marched with Eumenes to Cilicia in the autumn of 322 BC and added the formidable Silver Shields to his army. Perdiccas then gave Eumenes his orders, and marched to Pisidia. The native Isaurians and Larandians living here had revolted, murdering Alexander's satrap. Perdiccas campaigned against them next, easily conquering and destroying their cities in "short and brutal struggles", acquiring great amounts of plunder and prestige; "Victorious in the field ... Perdiccas now enjoyed his greatest success".

### Marriage and war

To strengthen his control over the empire when his authority was weak, Perdiccas had agreed to marry Nicaea, the daughter of Antipater, the regent of Macedon. But now, in the winter of 322-321 BC, with his position greatly strengthened, Perdiccas was reconsidering the engagement. Furthermore, Olympias, mother of Alexander the Great, offered him the hand of Cleopatra of Macedon, who was residing at Sardis. Eumenes urged Perdiccas to marry Cleopatra, while Perdiccas' brother Alcetas advised marriage to Nicaea. Alcetas' faction believed that Perdiccas, in control of the royals, imperial army, and treasuries, could afford to wait for Antipater's death (he was very old) instead of incurring his wrath; Eumenes' faction argued Perdiccas ought to begin to formally rule and that the dual kingship of Philip III and Alexander IV was a sham.
Rejecting Nicaea here would begin war with Antipater; as Perdiccas had yet to deal with Antigonus, he married Nicaea for the time being. During this winter, Antipater, having subdued Athens in the Lamian War, deferred the decision regarding the Samian exiles to Perdiccas; they were allowed to return to Samos on Perdiccas' order.

#### Bid for kingship

Perdiccas decided, however, that he wished to win the Macedonian throne, and had designed a plan for this; marriage to Cleopatra, and the return of Alexander's body, son (Alexander IV), and brother (Philip III) to Macedonia with Olympias' approval which, combined, would have made him "invincible" and virtually guaranteed the kingship. Given the intellectual disability of Philip III and the limited acceptance of the infant, Alexander IV, due to his mother being a Persian, the marriage in particular would have given Perdiccas a claim as Alexander's true successor as king, not merely as regent. Feeling "full of confidence and well able to handle all his rivals," Perdiccas set about planning his march on Macedon.
At around the same time, Cynane, Alexander's half-sister and widow of Amyntas IV, arranged for her daughter, Eurydice II, to marry the king, Philip III. Perdiccas, knowing this marriage would undermine his control over Philip III, sent an army under his brother Alcetas to order Cynane to return to Macedon. Cynane refused, and Alcetas' army killed her. Whether Perdiccas ordered this killing or not is debated, but it initiated a reversal of his ascendancy; "His officers grew increasingly suspicious of his aspirations, the common soldier was alienated by his acts of barbarity". Perdiccas' army was furious at Cynane's murder and effectively mutinied. This widespread discontent compelled Perdiccas to spare Eurydice II and marry her to Philip III after all, eroding his control over the royal family. Though Perdiccas was able to regain overall control, this incident probably demonstrated to him that "the marriage to Cleopatra, despite the risks involved, was essential if the empire was to remain intact". Eumenes, accordingly, was sent by Perdiccas to Cleopatra with gifts to discuss marriage once again, and plans were set in place for the marriage to go forward.
Perdiccas had, in the meantime, ordered Antigonus to stand trial for insubordination (failing to help Eumenes in Cappadocia) and other charges. Antigonus was an entrenched and powerful satrap in Asia Minor; his refusal of Perdiccas' order undermined the authority of his government and Perdiccas wanted to rectify this. In response Antigonus, fearing confrontation with the regent, fled to Antipater's court in Macedon, bringing news of not only Perdiccas' murder of Cynane, but his kingly aspirations and intention to marry Cleopatra instead of Nicaea. Craterus and Antipater, having subdued most of Greece in the Lamian War, were infuriated by Antigonus' news. They suspended their plans for more campaigns in Greece and prepared to march into Asia and depose Perdiccas.

## Civil war and invasion of Egypt
### Theft of the body of Alexander the Great

In late 321 and early 320 BC, as part of his kingly aspirations, Perdiccas intended to send Alexander's body back to Aegae in Macedonia, the traditional place of burial for the Macedonian Argead Royal Family. The officer Arrhidaeus (not the king) was chosen to escort the body back to Macedonia, having constructed an elaborate funeral carriage. Perdiccas had informed Arrhidaeus of his plans, but Arrhidaeus began conveying Alexander's body to Egypt instead of Macedon, and met no resistance as he did so. Ptolemy, who had already come to an understanding with Antipater and Craterus, had probably colluded with Arrhidaeus and Archon, satrap of Babylon in order to have Alexander's body go to Egypt. Perdiccas, enraged by this news, sent an army to recover the body, but Ptolemy defeated this force and successfully brought Alexander's remains back to Egypt, where they were housed in the city of Memphis.
Since the Partition of Babylon, Ptolemy had conquered Cyrenaica without Perdiccas' approval, and within a year of gaining his satrapy had unlawfully executed Cleomenes, the officer Perdiccas had attached to him. Perdiccas, who already distrusted Ptolemy, regarded his diverting of Alexander's body as an unacceptable provocation, "an act of war", and after convening his officers decided to invade Egypt.

### Campaign against Ptolemy

Perdiccas' strategy was for his supporters to hold Asia Minor against Antipater and Craterus while he brought the royal army, and kings (Philip III and Alexander IV), south to eliminate Ptolemy. Perdiccas gave Eumenes of Cardia supreme command (as autokrator) to hold the Hellespont, and ordered Alcetas and Neoptolemus to obey Eumenes. Cleitus the White was ordered to aid Eumenes navally. Perdiccas probably expected to be able to defeat Ptolemy and then turn to combat Antipater and Craterus. Before Perdiccas left Pisidia, he attempted once more to entreat Cleopatra of Macedon to marry him, now needing the increased authority the marriage would bring, but she refused, not knowing who would win the war to come. Perdiccas marched to Cilicia first, deposing the satrap Philotas due to his friendship with Craterus, replacing him with one Philoxenus.
He prepared a fleet there while sending Docimus to Babylon to supplant the satrap Archon for collusion with Ptolemy. Perdiccas also prepared another fleet, led by Sosigenes of Rhodes and Aristonous, to conquer Cyprus and the Cypriot kings who had allied themselves to Ptolemy. As he was heading south, Perdiccas, having heard that Alcetas and Neoptolemus were refusing to work under Eumenes, ordered them once again to subordinate themselves to him. Finally, a third fleet led by Attalus, his brother-in-law, carried Perdiccas' sister Atalante and shadowed Perdiccas' army on their southward march. Docimus conquered Babylon and killed Archon in battle, while Perdiccas reached Damascus and deposed Laomedon, satrap of Syria for Ptolemaic sympathies. Soon after arriving in Egypt, Perdiccas may have heard of Eumenes' victory over Neoptolemus, who had defected to Antipater and Craterus. With this boost in morale, and when further reinforcements joined him, Perdiccas marched towards the Nile.

#### Fording of the Nile and the Camel's Rampart

Ptolemy had been fortifying his satrapy for two years, believing war with Perdiccas was highly likely, and this greatly contributed to Perdiccas' difficulties and ultimate defeat. Perdiccas reached the most easterly tributary of the Nile near Pelusium, and discovered that the opposite side was garrisoned. He had his troops construct a dam, probably intending to lower the water levels to ease a crossing, but the force of the river broke it apart. It is possible that Perdiccas' invasion occurred while the Nile was flooding. In any case, the destruction of the dam led some officers in Perdiccas' camp to defect; Perdiccas, in response, successfully inspired his army with gifts and titles to continue the war effort.
Perdiccas then decamped, not informing his soldiers where he intended to march. He travelled swiftly upstream to find a suitable point to cross, soon coming across a ford which led to the cities of Tanis and Avaris on the other side of the Nile. However, a fort defended by a Ptolemaic force known as the 'Camel's Rampart' (Kamelon Teichos) inhibited his advance. Perdiccas then ordered his army to attack, leading a "daring" assault on the fortress at dawn. Perdiccas' deployed his war elephants first, then the hypaspists and Silver Shields, leading the cavalry in the rear in case Ptolemy arrived. When a large army under Ptolemy then arrived to reinforce the fort, denying Perdiccas an easy victory, Perdiccas, undaunted, renewed the assault. His infantry attempted to escalade the walls while his elephants destroyed Ptolemaic defenses. The fighting continued inconclusively for a considerable amount of time, with heavy losses for both sides, before Perdiccas finally broke off the siege and marched back to his camp.
That same night, Perdiccas broke camp again and marched to another ford, this one near Memphis. Here, Perdiccas placed his elephants upstream of this new crossing, so as to block the currents that would otherwise sweep away his men, and his cavalry downstream, to catch any unlucky enough to be swept away regardless of the elephants' makeshift dam.
For a time this "clever" strategy worked, enabling a sizeable contingent of Perdiccas's army, led by Perdiccas himself, to cross the river and reach an island at its center. Many drowned in the attempt, however, and soon the elephants began to sink in the mud of the riverbed, and the currents rose quickly. This proved to be a disaster for Perdiccas, as he had to abandon the crossing, leaving many of his infantry stranded on the island. Perdiccas had no choice but to return with his men. Most of this contingent drowned trying to make it back to the eastern bank, many being eaten by crocodiles. Perdiccas' losses totaled 2,000, including prominent officers.

### Assassination

Following what was so far a disastrous campaign, a mutiny broke out amongst Perdiccas' soldiers, who were disheartened by his failure to make progress in Egypt. Angry at his incompetence and probably colluding with Ptolemy, Perdiccas was murdered by his officers (Peithon, Antigenes, and Seleucus), probably in the summer of 320 BC, roughly three years after he had assumed the regency. His officers and the rest of his army defected to Ptolemy.
News of Eumenes' victory at the Battle of the Hellespont in 320 BC where Craterus and Neoptolemus were killed, which would have instantly restored Perdiccas' authority, arrived in Egypt one day after his assassination. Anson notes that "if the news of Eumenes' victory over Craterus had arrived sooner, the entire history of the post-Alexander era might have been dramatically altered; Perdiccas might have emerged supreme, the successor of Alexander and the ruler of the vast Macedonian empire, with the inauguration of a new royal family". What became of Alexander's signet ring that Perdiccas carried, and even whether he brought it into Egypt, is not known.

## Legacy
### Character

The ancient accounts are largely negative toward Perdiccas, claiming that, though "outstanding on the battlefield", he was arrogant, high-handed, and imperious. Diodorus Siculus calls him phonikos (φονικός), a "man of slaughter". This may be due to the "surpassing rivalry" and enmity Perdiccas had with Ptolemy, whose now lost account served as the basis for the surviving sources (chiefly Arrian) we have for Perdiccas' career. The other characteristic regularly ascribed to Perdiccas by ancient sources is boldness.
Although Perdiccas was evidently a capable leader and effective soldier, a "military man", he is seen to have lacked the qualities his position as regent required. His rule was authoritarian and abrasive, winning him little love from the rank and file, and his punishments were often brutal. Anson believes that Perdiccas "was not a man to be crossed" and that "most acceded to his demands in his presence rather than incur his wrath". Conversely, Romm writes that "When a leader has failed, the very qualities that made him a leader suddenly appear as flaws. Perdiccas' arrogance and bloody-mindedness were no more pronounced than Alexander's ... but Alexander, unlike the hapless Perdiccas, knew little of failure".

### Political legacy and motives

Perdiccas' death and the transferring of the regency to Antipater has been seen as marking the end "for the empire as Alexander had envisioned it", as Perdiccas was not only quite close to Alexander but, like Alexander, had chosen to centre the empire at Babylon. Waterfield believes that since Perdiccas represented direct succession from Alexander himself, his assassination was a "momentous step".
Perdiccas' motives are debated, though he is typically held to have acted from ambition. Some, such as Romm, believe he may have acted out of a desire to protect Alexander IV and maintain the unity of Alexander's empire. Anson disbelieves this, citing Perdiccas' duplicitous communications with the Aetolian League against Antipater. Whether for ambition or loyalty, it is agreed that Perdiccas sought to "hold Alexander's legacy intact". Tarn writes that "Perdiccas ... was a brave and good soldier; he was probably loyal to Alexander's house, and meant to keep the empire together; but he saw that someone must exercise power, and he meant it to be himself". The regime that succeeded Perdiccas following the Partition of Triparadisus lasted only a few years, shorter than Perdiccas' regency.
Heckel's view is that "Perdiccas' career is an unfortunate tale of lofty ideals combined with excessive ambition and political myopia", but also that Perdiccas' attempts at keeping Alexander's empire united are "to be admired" and "suggests that he understood Alexander's policies". In sum, that he was "a great but flawed man, a victim of his own success and the envy of others".
