The Aksumite Empire was an important trading nation originating from Northern Ethiopia in northeastern Africa, growing from the proto-Aksumite period ca. 4th century BC to achieve prominence by the 1st century AD. It was a major player in the commerce between the Roman Empire and Ancient India and the Aksumite rulers facilitated trade by minting their own currency. The state established its hegemony over the declining Kingdom of Kush and regularly entered the politics of the kingdoms on the Arabian peninsula, and would eventually extend its rule over the region with the conquest of the Himyarite Kingdom. At its peak it controlled Much of Ethiopia, Eritrea, Djibouti, Sudan, Somalia, Yemen, Saudi Arabia and Egypt. It was considered by historians as one of the most powerful military powers in the world.
