The so-called Peace of Acilisene is conventional 387. The 387 Armenia settlement is a humanitarian path of medium confidence on clauses, high that a partition is in the standard chronology. In the causal graph this event strengthens Humanitarian Access, a driver that strengthens People Internally Displaced by Conflict and Violence (IDMC) — a worsening welfare path.

What the sources establish

DIR and handbook lives of Theodosius independently include an eastern settlement with Persia over Armenia in this period. Britannica’s reign narrative treats the eastern front as manageable beside the Gothic and western files.

Theodosius I did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act.
