Biryawaza was a powerful ruler in the area of Egyptian controlled Syria in the middle fourteenth century BC.
[1] In the Amarna letters, Biryawaza was ordered by his Egyptian overlords to take armed action against Labaya's sons (EA 250).
In another Amarna letter, King Burna-Buriash II of Babylonia said Biryazawa attacked a Babylonian caravan sending gifts to Pharaoh Akhenaten.
Biryawaza may have been of an Indo-European maryannu caste similar to that which ruled the Mitanni and later, the Hittites.
