Overview
Archelaus (; fl. during the latter half of the second century BC and first half of first century BC, died by 63 BC) was a prominent Greek general who served under King Mithridates VI of Pontus in northern Anatolia and was also his favorite general.
Family and early life
Archelaus was a Cappadocian Greek nobleman, possibly of Macedonian descent, from unknown parents. Perhaps his ancestors descended from those Greeks who arrived in Anatolia after the expedition of Alexander the Great. He had a brother called Neoptolemus and his family were active in the Pontic Court. As he was a friend of Mithridates VI, the Pontic King gave Archelaus the court title of philos.
Along with Neoptolemus they both rose to prominence during the wars of Mithridates VI on the northern shores of the Black Sea. Archelaus was a prominent Pontic general during the First Mithridatic War (89 BC-85 BC). In 88 BC as a part of the First Mithridatic War, Archelaus and his brother were involved in a military campaign with the Pontic army against King Nicomedes IV of Bithynia. On the Amnias River the brothers had the command of the advance guard and won their first victory of the war. Neoptolemus then went on to defeat a Roman-led army at Protopachium, probably without his brother. Archelaus was next involved in Mithridates VI’s successful military campaign in conquering most of the Roman Province of Asia. Archelaus had attacked a city called Magnesia ad Sipylum or Magnesia on the Maeander. This attack failed and Archelaus was wounded in the fighting.
In the late summer or autumn of 88 BC or perhaps in 87 BC, Mithridates VI had given Archelaus the command of his large fleet and army to conquer Athens. Archelaus and the Pontic army were sent to Greece, in response to the Athenians wanting to break free from Roman rule and Mithridates VI wanting to conquer them. On their way to Athens, Archelaus captured the Cyclades Islands and the Greek island of Delos. When Archelaus and the Pontic army arrived in Athens, they occupied Piraeus. After occupying Athens the Pontic army spent three days fighting with Quintus Bruttius Sura, a legate to the propraetor of Macedonia, with his small detachment of Roman soldiers. The presence of the Pontic army under the command of Archelaus encouraged citizens from Southern Greece to revolt against Roman rule.
