Read the full account

In 301 the tetrarchy issued the Edict on Maximum Prices, a long tariff of goods, wages, and freight, with capital threats against sellers who exceeded ceilings. Fragments survive on stone. Diocletian’s government is the heading.

Context

Inflation was real. Death for a loaf-price is still coercive. The edict failed as a market machine, as later historians agree, and could punish the poor seller as well as the speculator.

Diocletian’s documented role is bounded by other offices and collaborators named in the sources below.

Why it matters

Fragments are not a supermarket. Split later scholarly access as improving.
