What is "gdrt"

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/Addi-Galamo in northern Ethiopia.

GDRT has been equated with the anonymous king of the Monumentum Adulitanum, which would date his reign c. 200 – c. 230. However, the two rulers are usually thought to be distinct. However the French scholar Christian Robin, studying the inscriptions at al-Mis`al in Yemen, has shown that GDRT, and his successor `DBH, lived in the earlier half of the 3rd century.
