Orontid dynasty

The Orontid dynasty, also known as the Eruandids or Eruandunis, ruled the Satrapy of Armenia until 330 BC and the Kingdom of Armenia from 321 BC to 200 BC. The Orontids ruled first as client kings or satraps of the Achaemenid Empire and after the collapse of the Achaemenid Empire established an independent kingdom. Later, a branch of the Orontids ruled as kings of Sophene and Commagene. They are the first of the three royal dynasties that successively ruled the antiquity-era Kingdom of Armenia (321 BC–428 AD).
