The Argead dynasty was an ancient Greek royal house. They were 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 Macedonia 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.
The words "Argead" and "Argive" derive (via Latin Argīvus) from the Greek Ἀργεῖος (Argeios), "of or from Argos", and is first attested in Homer, where it was also used as a collective designation for the Greeks ("Ἀργείων Δαναῶν", Argive Danaans). The Argead dynasty claimed descent from the Temenids of Argos, in the Peloponnese, whose legendary ancestor was Temenus, the great-great-grandson of Heracles. In the excavations of the royal Palace at Aegae Manolis Andronikos discovered in the "tholos" room (according to some scholars "tholos" was the throne room) an inscription relating to that belief. This is testified by Herodotus, in The Histories, where he mentions that three brothers of the lineage of Temenus, Gauanes, Aeropus and Perdiccas, fled from Argos to the Illyrians and then to Upper Macedonia, to a town called Lebaea, where they served the king. The latter asked them to leave his territory, believing in an omen that something great would happen to Perdiccas. The boys went to another part of Macedonia, near the garden of Midas, above which mount Bermio stands. There they made their abode and gradually formed their own kingdom. Herodotus also relates the incident of the participation of Alexander I of Macedon in the Olympic Games in 504 or 500 BC where the participation of the Macedonian king was contested by participants on the grounds that he was not Greek. The Hellanodikai, however, after examining his Argead claim confirmed that the Macedonians were in fact Greek and allowed him to participate.
According to Thucydides, in the History of the Peloponnesian War, the Argeads were originally Temenids from Argos, who descended from the highlands to Lower Macedonia, expelled the Pierians from Pieria and acquired in Paionia a narrow strip along the river Axios extending to Pella and the sea. They also added Mygdonia in their territory through the expulsion of the Edoni, Eordians, and Almopians.
