The Argead dynasty (Greek: Ἀργεάδαι) was an ancient Greek royal house. They were the founders and the ruling dynasty of Macedon from about 700 to 310 BC. Their tradition, as described in ancient Greek historiography, traced their origins to Argos, in southern Greece, hence the name Argeads or Argives. Initially the rulers of the homonymous tribe, by the time of Philip II they had expanded their reign further, to include under the rule of Macedonia all Upper Macedonian states. The family's most celebrated members were Philip II of Macedon and Alexander the Great, under whose leadership the kingdom of Macedonia gradually gained predominance throughout Greece, defeated the Achaemenid Empire and expanded as far as Egypt and India. The mythical founder of the Argead dynasty is King Caranus.
