query: When was the Kingdom of Aksum founded?
passage: Kingdom of Aksum
The Kingdom of Aksum (also known as the Kingdom of Axum, or the Aksumite Empire) was an ancient kingdom located in what is now Tigray Region (northern Ethiopia) and Eritrea.[2][3]. Axumite Emperors were powerful sovereigns, styling themselves King of kings, king of Aksum, Himyar, Raydan, Saba, Salhen, Tsiyamo, Beja and of Kush.[4] Ruled by the Aksumites, it existed from approximately 100 AD to 940 AD. The polity was centered in the city of Axum and grew from the proto-Aksumite Iron Age period around the 4th century BC to achieve prominence by the 1st century AD. Aksum became a major player on the commercial route between the Roman Empire and Ancient India. The Aksumite rulers facilitated trade by minting their own Aksumite currency, with the state establishing its hegemony over the declining Kingdom of Kush. It also regularly entered the politics of the kingdoms on the Arabian Peninsula and eventually extended its rule over the region with the conquest of the Himyarite Kingdom. The Manichaei prophet Mani (died 274 AD) regarded Axum as one of the four great powers of his time, the others being Persia, Rome, and China.[2][5]
passage: Classical African civilization
Christianity was introduced into the country by Frumentius, who was consecrated first bishop of Ethiopia by Saint Athanasius of Alexandria about 330. Frumentius converted Ezana, who left several inscriptions detailing his reign both before and after his conversion. One inscription found at Axum, states that he conquered the nation of the Bogos, and returned thanks to his father, the god Mars, for his victory. Later inscriptions show Ezana's growing attachment to Christianity, and Ezana's coins bear this out, shifting from a design with disc and crescent to a design with a cross. Expeditions by Ezana into the Kingdom of Kush at Meroe in Sudan may have brought about its demise, though there is evidence that the kingdom was experiencing a period of decline beforehand. As a result of Ezana's expansions, Aksum bordered the Roman province of Egypt. The degree of Ezana's control over Yemen is uncertain. Though there is little evidence supporting Aksumite control of the region at that time, his title, which includes "king of Saba and Salhen, Himyar and Dhu-Raydan" (all in modern-day Yemen), along with gold Aksumite coins with the inscriptions, "king of the "Habshat"" or "Habashite", indicate that Aksum might have retained some legal or actual footing in the area.
