Read the full account

The tetrarchy multiplied courts and field armies, a security design that sat on the new census-tax.

Context

More soldiers can reduce invasion (improving military row). This stores the fiscal-sustainability risk of paying four courts and a larger army.

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

Larger army, more emperors, more courts. Stabilization elsewhere. This stores the cost side.

Why it matters

A legion is not a church fire. Split 303.
