Perdiccas III of Macedon
king of Macedonia from 365 BC to 360 BC

Perdiccas III (Greek: Περδίκκας Γ΄) was king of the Hellenic kingdom of Macedonia from 365 BC to 360 BC, succeeding his brother Alexander II.
History
Son of Amyntas III and Eurydice, he was a child when in 369 BC his brother Alexander II was killed by their brother-in-law Ptolemy of Aloros, who then ruled as regent. In 365 BC, Perdiccas killed Ptolemy and assumed government.
There is very little information about the reign of Perdiccas III. He was at one time engaged in hostilities with Athens over Amphipolis, and he was distinguished for his patronage of men of letters. Among these we are told that Euphraeus of Oreus, a disciple of Plato, rose so high in Perdiccas's favour as to completely govern the young king and to exclude from his society all but philosophers and geometers.
He also served as theorodokos in the Panhellenic Games that took place in Epidaurus around 360/359 BC.
In 360 BC, Perdiccas tried to reconquer upper Macedonia from the Illyrian Bardylis, but the expedition ended in disaster, with Perdiccas being killed. Diodorus Siculus attests that four thousand men had died in the expedition, and that the remainder, panic-stricken, had become exceedingly afraid of the Illyrian armies and had lost heart for continuing the war.
Succession
Perdiccas was succeeded by his infant son, Amyntas IV. The throne was soon usurped by Perdiccas's younger brother Philip II.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Perdiccas III of Macedon”, the useful work is to connect “king of Macedonia from 365 BC to 360 BC” to the records capable of establishing context and consequence.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q318466. VIAF identifies the subject as 642162844749673240004. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1997.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
