What it was
Nine archons held office for a year: the eponymous archon, after whom the year was named; the basileus, who handled religious business inherited from the kings; the polemarch, originally the war leader; and six thesmothetai who managed the courts.
In the archaic period this was the effective government of Athens. Membership of the Areopagus for life followed from having held it, which made the office the route into the aristocratic council.
How it worked
Selection was originally by election from the highest property classes. From 487 BCE the archons were chosen by lot from a pre-selected group, which changed the character of the office decisively: an office filled by lottery cannot be a prize worth competing for.
The eponymous archon's year is the basis of Athenian dating, and the archon lists are one of the useful chronological frameworks for Greek history.
Powers and limits
After the lot was introduced the archons administered rather than led. Real political direction passed to the generals, who continued to be elected, and to the speakers in the assembly.
The polemarch's military role passed to the strategoi. At Marathon in 490 BCE the polemarch Callimachus still cast a deciding vote on whether to fight, which is close to the last moment the office mattered militarily.
How it changed
Property qualifications for the office were lowered progressively, and by the later fifth century the lowest census class was in practice admitted.
The office survived into the Roman period as a civic dignity with the eponymous function intact and the power gone.
What the evidence supports
Selection by lot from 487 BCE is attested and is the decisive change.
Recorded in Aristotle's Constitution of the Athenians, which dates the change and names the year. The move from election to lot transferred political leadership to the elected generalship.
Archon lists provide a dating framework.
Preserved partly in inscriptions and partly in later authors; gaps and disputes remain for the earlier period.
The archaic archonship's powers are described only in retrospect.
Aristotle writes centuries later and reconstructs the early constitution from tradition and inference.

How to read the evidence labels
- Evidence level: Documented
- Supported by a named primary text or by excavated material evidence.
- Evidence level: Probable
- Supported by strong inference that most specialists accept.
- Evidence level: Disputed
- Substantial specialist disagreement exists; competing readings are stated.
- Evidence level: Literary
- Belongs to poetic or mythological construction rather than to history.
- Evidence level: Mythological
- Belongs to shared religious or mythic tradition rather than to any single text.
- Evidence level: Unknown
- The available evidence is insufficient to decide.
These labels describe the status of the evidence, not our confidence in a conclusion. A claim marked Literary is not a claim we doubt; it is a claim about what kind of thing a poem is.
