Ezana of Aksum

Ezana introduced a standardized gold coinage system bearing his image and Christian crosses. These coins facilitated trade across the Red Sea and Indian Ocean, strengthening Aksum's economy and international standing.

Ezana converted to Christianity under the influence of his tutor Frumentius, making Aksum the first Christian state in Africa. He declared Christianity the official religion, ending the worship of local deities like Astar and Mahrem.

Ezana led a military campaign that destroyed the Kingdom of Kush, sacking its capital Meroe. This conquest ended the Nubian kingdom's independence and extended Aksumite control over the Nile Valley, as recorded in his victory inscriptions.
