Later histories print Sasanian-Roman and internal wars in which fire-cult and church pressured populations
Iranica’s historical review and encyclopedia chapters on late antique wars describe deportations and confessional pressure as later told. The dated carrier is that 2005 history cluster. In the causal graph this event strengthens Forced-Displacement Scale, a driver that strengthens People Internally Displaced by Conflict and Violence (IDMC) — a worsening welfare path.

Iranica’s historical review and encyclopedia chapters on late antique wars describe deportations and confessional pressure as later told. The dated carrier is that 2005 history cluster. Displacement path of medium confidence; he is a heading, not a general.
Context
Do store later state-religion war as later war.
Zoroaster is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Printed late-antique deportations are not a founder’s campaign diary.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
Zoroaster
PersonDirect responsibility
responsibility level 0.21 · verified
Named prophet as heading of later hymns and state religion. Redactors, Sasanian kings, and later Parsi printers publish the instrument.

What the sources establish
Historical review (https://www.iranicaonline.org/articles/zoroastrianism-i-historical-review/ (opens in a new tab); Encyclopaedia Iranica).
Later competitions, monuments, translations, UNESCO listings, and museums are not converted into extra lifetime acts. That reading is an impact-path choice, not a property stored on the Fact itself. Confidence is stated on the impact path. A later English edition is not a recovered autograph. If a number is not in the two records named above, it is not supplied here.
