Perdiccas

Perdiccas (Greek: Περδίκκας, Perdikkas; c. 355 BC – 321/320 BC) became a general in Alexander the Great's army and participated in Alexander's campaign against Persia. Following Alexander's death, he rose to become supreme commander of the imperial army and regent for Alexander's half brother and intellectually disabled successor, Philip Arridaeus (Philip III).
He was the first of the Diadochi who fought for control over Alexander's empire but in his attempts to establish a power base and stay in control of the empire, he managed to make enemies of key generals in the Macedonian army, Antipater, Craterus and Antigonus Monophtalmus, who decided to revolt against the regent. In response to this formidable coalition and a provocation from another general, Ptolemy, Perdiccas invaded Egypt, but when the invasion foundered his soldiers revolted and killed him.

According to Arrian, Perdiccas was a son of the Macedonian nobleman, Orontes, a descendant of the independent princes of the Macedonian province of Orestis. While his actual date of birth is unknown, he would seem to have been of a similar age to Alexander.

As the commander of a battalion of the Macedonian phalanx, heavy infantry, Perdiccas distinguished himself during the conquest of Thebes (335 BC), where he was severely wounded. Subsequently, he held an important command in the Indian campaigns of Alexander. In 324 BC, at the nuptials celebrated at Susa, Perdiccas married the daughter of the satrap of Media, a Persian named Atropates. When Hephaestion unexpectedly died the same year, Perdiccas was appointed his successor as commander of the Companion cavalry and chiliarch. As Alexander lay dying on 11 June 323 BC, he gave his ring to Perdiccas.

Following the death of Alexander, his generals met to discuss what should be their next steps. Perdiccas proposed that a final decision wait until Alexander's wife Roxana, who was pregnant, had given birth. If the child was a boy, then Perdiccas proposed that the child would be chosen as the new king. This meant that Perdiccas would be the regent and effectively the ruler of Alexander's empire until the boy was old enough to rule on his own. Despite misgivings amongst the other generals, most accepted Perdiccas' proposal.

However, the infantry commander, Meleager, disagreed with Perdiccas' plans. Meleager argued in favour of Alexander's half brother, Arridaeus, who he considered to be first in line of succession. The infantry supported this proposal with Meleagar's troops willing to fight in favour of Arridaeus.

Through the Partition of Babylon a compromise was reached under which Perdiccas was to serve as "Regent of the Empire" and supreme commander of the imperial army. Arridaeus and the unborn child of Alexander's wife Roxana (the future Alexander IV of Macedon) were recognized as joint kings. 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. 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. Alexander the Great's second wife, Stateira, was murdered. Perdiccas had Meleager arrested and murdered.

Perdiccas' authority as regent and his control over the royal family were immediately challenged. Perdiccas appointed Leonnatus, one of Alexander's bodyguards or somatophylakes, as satrap of Hellespontine Phrygia on the western coast of Asia Minor. However, instead of assuming that position, Leonnatus sailed to Macedonia when Alexander's sister, Cleopatra, widow of King Alexander I of Epirus, offered her hand to him. Upon learning of this, in spring 322 BC Perdiccas marched the imperial army towards Asia Minor to reassert his dominance as regent. 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 around the same time, Cynane, Alexander's half-sister, arranged for her daughter, Eurydice II, to marry the joint king, Arridaeus (Philip III). Fearful of Cynane's influence, Perdiccas ordered his brother Alcetas to murder her. The discontent expressed by the army at the plan to murder her and their respect for Eurydice as a member of royal family persuaded Perdiccas not only to spare her life but to approve of the marriage to Philip III. Despite the marriage, Perdiccas continued to firmly hold control over the affairs of the royal family.

As regent and commander-in-chief, Perdiccas saw it as important that he consolidate Alexander's empire. A key step in achieving this was to conquer Cappadocia which still remained under Persian rule. However, Antigonus I Monophthalmus, the Macedonian satrap of Pamphylia and Lycia, was unwilling to support Perdiccas when in 322 BC Perdiccas successfully invaded Cappadocia. When Perdiccas ordered Antigonus to appear before his court, Antigonus fled to Antipater's court in Macedonia.

To strengthen his control over the empire, Perdiccas agreed to marry Nicaea, the daughter of the satrap of Macedonia, Antipater. However, he broke off the engagement in 322 BC when Olympias, mother of Alexander the Great, offered him the hand of Alexander's full sister Cleopatra. Given the intellectual disability of Philip III and the limited acceptance of the boy, Alexander IV, due to his mother being a Persian, the marriage would have given Perdiccas a claim as Alexander's true successor, not merely as regent.

As a result of these events and actions, Perdiccas earned Antipater's animosity, while Antigonus had reason to fear Perdiccas. Another general, Craterus, was also unhappy at being ignored by Perdiccas despite his important position within the army when Alexander was alive. So Antipater, Craterus and Antigonus agreed to revolt against Perdiccas.

In late 321 BC, Perdiccas had sent Alexander's remains to an intended tomb that had been prepared in Aegae in Macedonia, the town where Alexander had been proclaimed king. However, when Alexander's remains arrived in Damascus, Ptolemy, the satrap of Egypt, was able to persuade those accompanying the remains that Alexander had wanted to be buried in Egypt. So Alexander's remains were brought to Alexandria in Egypt. Perdiccas regarded Ptolemy's action as an unacceptable provocation and decided to punish Ptolemy by invading Egypt.

Perdiccas' most loyal supporter was Eumenes, satrap of Cappadocia and Paphlagonia. Leaving the war in Asia Minor to Eumenes, Perdiccas marched to attack Ptolemy in Egypt. Eumenes managed to defeat and kill Craterus in a battle that took place near the Hellespont. Perdiccas reached Pelusium but failed to cross the Nile. A mutiny broke out amongst his troops, who were disheartened by Perdiccas' failure to make progress in Egypt and exasperated by the severity of his discipline. Perdiccas was assassinated by his officers (Peithon, Antigenes, and Seleucus) some time in either 321 or 320 BC.
