Who were the original inhabitants of Ethiopia?

The original inhabitants of Ethiopia are believed to be Cushitic-speaking peoples who migrated from the Nile Valley in the north and from the Horn of Africa in the east. These early inhabitants established the Kingdom of Aksum, which flourished from the 1st to the 7th century AD and was one of the most powerful kingdoms in the region. The Aksumites were known for their trade, their architecture, and their adoption of Christianity. After the fall of Aksum, the region was ruled by a series of local dynasties until the rise of the Ethiopian Empire in the 19th century.
