The Athenian Egyptian expedition ends in disaster about 454 BCE

About 454 BCE the Athenian expedition in Egypt was destroyed. The dated overseas killing-and-loss is not the 431 defensive crowding of Athens and not the Samian War. In the causal graph this event weakens Humanitarian Access, a driver that strengthens People Internally Displaced by Conflict and Violence (IDMC) — an improving welfare path.
