Final answer:
There is no specific empress named as responsible for the destruction of the Kingdom of Aksum; its decline was due to environmental degradation, reduction in trade, and socio-economic factors.
Step-by-step explanation:
The Empress who is often mentioned in discussions about the decline of the Kingdom of Aksum is not identified by a specific name. Contrary to the idea that a single ruler was responsible for the destruction of Aksum, historical evidence indicates that the decline was due to a combination of internal struggles, such as environmental degradation, and external pressures, like the cut-off from Red Sea trade routes due to Arab expansion. The Kingdom of Aksum was affected by soil erosion resulting from deforestation and agricultural practices, reducing its agricultural output. In addition, the emergence of Islamic power in the seventh century and the Arab control of Red-Sea trade weakened Aksum's economy. Thus, rather than the actions of an empress, it was a sequence of socio-economic factors and environmental issues that led to the gradual fall of the Aksumite Kingdom and its transition into a smaller entity, ultimately reincorporated into the emerging Kingdom of Ethiopia.
