Argead Dynasty Ruling house of ancient Macedonia from about 700 to about 311 BC; under their leadership the Macedonian kingdom was created and gradually gained predominance throughout Greece. From about 700 the founder of the dynasty, Perdiccas I, led the people who called themselves Macedonians eastward from their home on the Haliacmon (modern Aliákmon) River. Aegae (Edessa) became the capital, and by the reign of Amyntas I (6th century BC) Macedonian power extended eastward beyond the Axius (Axiós) River to dominate the neighboring Thracian tribes.
