Chaldean Catholic Archeparchy of Ahvaz
The Chaldean Catholic Archeparchy of Ahvaz (or Ahwaz)(informally called Ahvaz of the Chaldeans) is a non-Metropolitan archeparchy (Eastern Catholic archdiocese) of the particular Chaldean Catholic Church "sui iuris" (Syro-Oriental Rite in Syriac language) in Ahvaz, Khuzestan Province, southwest Iran.
Ahvaz
The city had two sections; the nobles of the city lived in one part while the other was inhabited by merchants. When the Arabs invaded the area in 640, the part of the city home to the nobility was demolished but the "Hūj-ī-stānwāčār" "Market of Khūz State", the merchant area, remained intact. The city was therefore renamed "Sūq al-Ahwāz", "Market of the "Khuz"", a semi-literal translation of the Persian name of this quarter - "Ahwāz" being the Arabic broken plural of "Hûz", taken from the ancient Persian term for the native Elamite peoples, "Hūja" (remaining in medieval "khūzīg" "of the "Khuzh"" and modern "Khuzestān" "Khuz State", as noted by Dehkhoda dictionary.
