Amdan Bayin is not the name of the ruler, but a honorific titles, and coins were struck with this title by different rulers for for several centuries at the beginning. Vocalization of titles is uncertain, as is their chronology and dates of reign to which belong. Proposed typological chronology is relative and tentative. Absolute chronology, based on metrology, iconography, style and palaeography, could be done in the future.

Himyarite Kingdom was an ancient kingdom in southern Arabia, centered in present-day Yemen, that flourished from about 110 BC to the 6th century AD. Emerging after the decline of the Sabaean kingdoms, the Himyarites united much of southern Arabia and controlled important trade routes linking the Mediterranean world, East Africa, and India. Their rulers grew wealthy from the incense and spice trade and maintained close commercial ties with the Roman and Persian worlds as well as the Kingdom of Aksum across the Red Sea. During its later centuries, the kingdom adopted Judaism as the religion of the royal court, leading to religious conflicts with neighboring Christian powers. The Himyarite Kingdom eventually declined after invasions by Aksumite and later Sasanian Persian forces in the 6th century AD.
