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.
