What it was
Four aediles — two plebeian, two curule — had charge of the city itself: streets, buildings, water, markets, weights and measures, public order, and the corn supply.
They also presided over several of the major public festivals, which is the fact that shaped the office's political meaning.
How it worked
Aediles regulated trade, fined those who encroached on public land, and prosecuted breaches of the market rules. Their jurisdiction over sales produced a body of rules on defects in goods and slaves that entered the legal tradition.
The games were funded partly by the state and largely by the holder. Spending far beyond the allowance was normal, expected, and effectively an investment: a memorable aedileship bought the name recognition needed for the praetorship.
Powers and limits
The aedileship had no imperium and commanded no army. Its power was administrative and its value was reputational.
That reputational logic made it a mechanism for the wealthy to convert money into office, and it is one of the clearest ways in which Republican politics favoured those who could afford to spend.
How it changed
The office was not formally required in the career ladder but was in practice near-essential for a man without a famous name.
Under the emperors its functions were transferred to imperial officials — the prefect of the corn supply, the curators of works and water — and the aedileship dwindled.
What the evidence supports
Aediles' expenditure on games was a recognised political investment.
Attested in the sources and in the careers themselves, where a spectacular aedileship is followed by electoral success.
The aedilician edict shaped the law of sale.
Rules on latent defects in goods and slaves, issued by aediles for the markets, are preserved in the legal sources.
The office's exact competences shifted over time.
The division between plebeian and curule aediles, and between their duties, is not consistently described.

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.
