Endubis

Endubis or Endybis (Greek: Ενδυβις) was a late-3rd-century sovereign of the Kingdom of Aksum in East Africa (modern-day Ethiopia and Eritrea). He was among the earliest rulers in the Africa to mint his own coins; according to Stuart C. Munro-Hay, "No other sub-Saharan African state issued its own independent coinage in ancient times -- indeed no other African state at all, since those in North Africa (Libya and Mauritania) fell under Roman dominion." The Aksumite currency of his reign was issued in gold, silver, and bronze or copper denominations and bore inscriptions in Koine Greek.
