In the first century AD the Aksumite Kingdom rose to power in the Tigray Region with its capital at Aksum and grew into a major power on the Red Sea, subjugating Yemen and Meroe. One of the early kingdoms to rise to power in the territory was the kingdom of D'mt in the 10th century BC, which established its capital at Yeha. Due to migration and imperial expansion, it grew to include many other primarily Afro-Asiatic-speaking communities, including Amhara, Oromos, Somalis, Tigray, Afars, Sidama, Gurage, Agaw and Harari, among others.
