Overview
Arsames I (Greek: ; ) seems to have taken control of Commagene, Sophene and Armenia in the year 260 BC after the death of his grandfather Orontes III, king of Armenia, and his father Sames, king of Commagene.
Name
"Arsames" is the Hellenized form of the Old Persian name Aršāma ("having a hero’s strength"), which was a common name within the Persian Achaemenid family as well as amongst the Persian elite of the Achaemenid Empire (550–330 BC). The name is a compound, composed of aršan ("male, hero") and ama ("strength"). The name is attested in Aramaic as ʾršm. The feminine form of the name, *Aršāmā (Greek Arsamē), is attested in the daughter of Darius the Great (522–486 BC).
Reign
The Seleucid Empire was always trying to overthrow the Armenian dynasties who still ruled the lands their forebears had in the time of the Achaemenid Empire.
Ziaelas of Bithynia found refuge at the court of king Arsames, and upon the death of king Nicomedes I of Bithynia Ziaelas returned to take the kingdom in 254 BC.
