Step-by-step explanation:
The Kingdom of Aksum was similar to other African kingdoms in that it gained power through its location on major trade routes. Aksum's strategic position adjacent to the Red Sea allowed it to flourish as a cosmopolitan trading hub, similar to other powerful African kingdoms that leveraged their geographical advantages for economic dominance.
This kingdom benefited from trade relations that extended across the ancient world, dealing in luxury goods such as gold, ivory, and spices, which contributed to its wealth and power. Moreover, Aksum was one of the earliest Christian states, further enhancing its global connections and cultural significance during its height from the first through the eighth centuries.
