Arsakes is a Greek form of the Old Persian name Aršaka or the Parthian Aršak, itself a diminutive of Old Persian 𐎠𐎼𐏁𐎠𐎴 (aršan), meaning "hero." The name is rooted in the dynastic tradition of the Arsacid rulers of the Parthian Empire, who adopted it as a marker of their lineage.Etymology and OriginsThe Greek form Ἀρσάκης (Arsákēs) derives ultimately from the Old Persian 𐎠𐎼𐏁𐎣 (R̥šakaʰ) or Parthian 𐭀𐭓𐭔𐭊 (Aršak). Linguists propose that the short form Aršaka/Aršak is a diminutive of aršan ("hero", “male”), so the name essentially means "little hero" or perhaps "heroic youth." As the dynastic name of the Arsacid dynasty, it appears on inscriptions and coins across the Parthian realm.Historical and Cultural SignificanceArsakes was borne by two distinct rulers of Parthia in the 3rd–2nd centuries BC. The first was Arsaces I (c. 247–211 BC), the founder of the Parthian Empire, who rebelled against Seleucid authority and established an independent Iranian kingdom. His successor, commonly titled “Arsaces II” (c. 211–191 BC), continued consolidating the state; in older scholarship he was sometimes misidentified as Artabanus I.Beyond Parthia, the name was adopted by several client kings and Armenian monarchs. Arsaces of Pontus (1st century BC) ruled as a Roman vassal, while Arsaces I through III governed Armenia at different periods: Arsaces I of Armenia (AD 35), Arshak II (c. 350–368), and Arshak III (378–387). The name also appears among Indo-Scythian rulers (e.g., a certain Arsakes) and later among Byzantine-Armenian nobles involved in court intrigues, such as the conspirator Arsaces of the 6th century.Notable BearersArsaces I of Parthia – founder of the Parthian Empire (3rd century BC)Arsaces II of Parthia – king of Parthia, formerly tagged as Artabanus IArsaces of Pontus – Roman client king of Pontus (1st century BC)Arsaces I–III of Armenia – Armenian kings between 35 and 387 ADArsaces (Indo-Scythian ruler) – minor early‑century ruler
