Later the Mediterranean trade of Aksum was ended by the encroachment of the Arabs in the 7th and 8th centuries. Gradually, Aksumite power shifted internally to the Agau (Agaw, or Agew) people, whose princes shaped a new Christian line in the Zagwe dynasty of the 12th–13th century.
How did the Aksum empire end?
The kingdom of Axum went in decline from the late 6th century CE, perhaps due to overuse of agricultural land or the incursion of western Bedja herders who, forming themselves into small kingdoms, grabbed parts of Aksum territory for grazing their cattle and who persistently attacked Axum's camel caravans.
What factors led to the fall of Aksum?
The main factors that led to the fall of the Aksum in the seventhcentury were climate change and the obstruction of internationaltrade routes around the Red Sea brought on by the growing supremacyof the Muslims in Ethiopia.
