He was the first son and namesake of the Pontic high-ranking officer Archelaus who participated in the Mithridatic Wars while his brother was the Pontic soldier Diogenes, who served in the army of King Mithridates VI of Pontus. His paternal uncle was the distinguished Pontic General Neoptolemus and the family of Archelaus were active in the Pontic Court.
