Artaxias IV (Armenian: Արտաշես Դ, also Artashir IV, r. 422–428 AD) served as the final Arsacid king of eastern Armenia under Sasanian suzerainty. Son of King Khosrov III (IV) and nephew of previous puppet monarchs, he ascended amid nakharar nobles’ desperate bid to revive dynastic rule after direct Persian control post-387 partition. Adopting the Persian throne-name Artashir to honor Sasanian overlords, his six-year reign as Christian vassal of Zoroastrian Persia ended when nobles—exasperated by royal weakness—begged Bahram V for annexation, abruptly terminating Armenia’s monarchy after nearly 1,000 years from Artaxias I’s founding.
Arsacid Desperation Post-Partition
Following the 387 NVarsak Treaty dividing Armenia (Rome 1/3, Persia 2/3), eastern highlands endured marzban governors like Veh Mihr Shapur. Arsacid remnants—Khosrov IV (c. 385–414, imprisoned), Sahak (412–422)—failed stabilizing fractious nakharars. Yazdegerd I briefly freed Khosrov (417–418); his death left vacuum. Nobles petitioned Bahram V (r. 421–438) for Arsacid restoration, enthroning Artaxias IV (422) as last hope against total absorption.
Symbolic Kingship as Artashir
Crowned in Artsakh or Dvin, Artaxias styled himself Artashir—deference to Ardashir I–V—ruling Persian Armenia’s core (Vaspurakan to Artsakh). No coins survive; Faustus Buzand and P’awstos note nominal authority: Christian rites persisted (Catholicos Isaac/Aristakes), yet kuchak Zoroastrian holdouts lingered. Tax collection, fortress oversight yielded to marzban veto; reign marked Arsacid sunset, echoing Pap’s regicide (374).
Nakharar Revolt and Dethronement
Artaxias alienated patrons: ineffective vs. Roman border raids, unable extracting tribute for Bahram’s wars. Nakharars—Mamikonian, Siunia heirs—lost faith, preferring direct Persian administration over puppetry. 428 petition: Bahram V deposed Artaxias, annexing Armenia as satrapy under Veh Mihr Shapur. Artaxias vanished—exile, execution unknown—ending Orontid-Artaxiad-Arsacid continuum from Artaxias I (189 BC).
End of Monarchy and Marzban Era
428 annexation ushered 100-year marzbanate (428–535): Persian governors enforced Zoroastrianism, Vardan Mamikonian’s 451 martyrdom sparked revolt. Vaspurakan nakharars resisted; Sahak II Bagratuni (c. 430s) claimed titular kingship in west. Artaxias IV’s fall prefigured Bagratid revival (885).
Legacy in Armenian Historiography
P’awstos Buzand laments Arsacid extinction; Khorenatsi traces Hayk-Orontes-Tiridates III to this terminus. Moderns view him transitional: Pap’s centralism yields nakharar dominance. Yerevan museums lack relics; symbolic as endpoint—from Tiridates I’s Nero diadem to Erato’s diadems. Hovnatanyan portraits envision Arsacid twilight.
Symbol of Dynastic Extinction
Artaxias IV embodies monarchy’s plea: nakharars crown, then behead last Artashes. Post-Gregory baptism, Nerses V poetry—from Artavasdes II’s captivity to Pap’s cup—his deposition axes sovereignty, birthing marzban-Vardanants struggles. For chroniclers, eternal reminder: noble disunity invites empires.
