High Quality Content by WIKIPEDIA articles! GDRT (also GDR, vocalized by historians as Gadarat) was a king of the Kingdom of Aksum (c.200), known for being the first king to involve Axum in the affairs of what is now Yemen. He is known primarily from inscriptions in South Arabia that mention him and his son BYGT (also vocalized as "Beyga" or "Beygat"). GDRT is thought to be the same person as GDR, the name inscribed on a bronze wand or sceptre that was found in an area near Atsbi and Dar`a near Addi Galamo in northern Ethiopia.
