Read the full account

Later histories treat 284–305 as a consolidation after the mid-century crisis: fewer successful secessions, rebuilt offices, held frontiers.

Context

Stabilization can be cohesion and can be tighter extraction. Split tax and persecution. This stores the relative cohesion of a holding state.

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

After Gallienus/Aurelian already began recovery. Diocletian consolidates. Not a golden age; still persecution and tax.

Why it matters

Holding an empire together after secession-crisis is a cohesion path of medium confidence.

Stabilization is not a rebate for burning scriptures.
