Aksum

From Conservapedia

The Kingdom of Aksum (alternatively Axum), located in present-day Ethiopia, traced its roots to the migration of Arabs across the Red Sea into the Horn of Africa in 1000 B.C. The kingdom had a written language called "Ge'ez" (a Semitic language using Arabic characters) and controlled the southwestern portion of the Arabian Peninsula.

The peak of its power was under the strong ruler named Ezana in A.D. 325-360. Ezana conquered Kush and destroyed the city of Meroe. He also converted to Christianity and a Coptic Church formed in the Aksum kingdom.

Aksum developed a coin currency and a unique architectural style called a "stelae", which consisted of large stone pillars. But in A.D. 710, the Muslims conquered Aksum and destroyed its big trading city known as Adulis.
