In December 69 CE Flavian troops entered Rome and Vitellius was killed, as Tacitus Histories print it. 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.
Read the full account
In December 69 CE Flavian troops entered Rome and Vitellius was killed, as Tacitus Histories print it. Vespasian was not in the city. Mucianus and Antonius Primus share the Italian campaign.
Context
Tacitus and Britannica independently date the December 69 fall of Vitellius. The Capitol burned in the fighting; later rebuilding is a neighbouring fiscal-building cluster, not this street.
Vespasian’s documented role is bounded by other offices and collaborators named in the sources below.
Conventional years are 9–79 CE. Surviving public files are later Suetonius, Tacitus, Josephus, coins, and encyclopedia pages. Vespasian did not typeset those later English pages. Dates here are received historical years.
Why it matters
Humanitarian-harm path via civil war in the capital. High confidence on the received outcome.

Antonius Primus and Mucianus’s side fought in Italy. Vespasian was still in the East. Complex shared Flavian victory, not a personal street killing.
