The Kingdom of Aksum, or the Aksumite Empire, was a kingdom in East Africa and South Arabia from classical antiquity to the Middle Ages, based in what is now northern Ethiopia and Eritrea, and spanning present-day Djibouti, Sudan, and Yemen. Emerging from the earlier Dʿmt civilization, the kingdom was founded in the 1st century. The city of Axum served as the kingdom's capital for many centuries until it relocated to Kubar in the 9th century due to declining trade connections and recurring invasions.
The Kingdom of Aksum was considered one of the four great powers of the 3rd century by Mani, the founder of Manichaeism, alongside Persia, Rome, and China. Aksum continued to expand under the reign of Gedara (c. 200–230), who was the first king to be involved in South Arabian affairs. His reign resulted in the control of much of western Yemen, such as the Tihama, Najran, al-Ma'afir, Zafar (until c. 230), and parts of Hashid territory around Hamir in the northern highlands until a joint Himyarite-Sabean alliance pushed them out. Aksum-Himyar conflicts persisted throughout the 3rd century. During the reign of Endybis (270–310), Aksum began minting coins that have been excavated as far away as Caesarea and southern India.
