Final answer:
Aksum, an ancient kingdom located in present-day Ethiopia and Eritrea, was linked to Rome through trade and the shared religion of Christianity. Its strategic location on the Red Sea enabled trade with various regions and the adoption of Coptic Christianity tied it to the Mediterranean.
Step-by-step explanation:
The Kingdom of Aksum was a notable civilization in sub-Saharan Africa linked to the Roman world through trade and religion.
Located in modern-day Ethiopia and Eritrea, Aksum's prosperity as a cosmopolitan center of commerce was facilitated by its strategic position on the Red Sea, enabling trade with the Mediterranean, the Nile, and the Indian Ocean.
It is known for its distinctive architectural accomplishments, like the monumental stelae, and for adopting Christianity early on, influenced by Egyptian Coptic practices.
In particular, Aksum's relationship with Rome was cemented by their shared interests in trade.
Through the port city of Adulis, Aksumites exchanged goods such as ivory, spices, and precious metals, which were coveted by the Roman Empire.
Furthermore, the fourth-century conversion of King Ezana to Christianity by the Syrian missionary Frumentius created religious ties with the Roman Christian world, as evidenced by cross symbols on Aksumite coins.
Aksum also maintained relations with other cultures and empires, including those in Arabia and the eastern Mediterranean.
These connections are visible in the kingdom's architecture and cultural practices.
