Ethiopians are the native inhabitants of Ethiopia, as well as the global diaspora of Ethiopia. Ethiopians constitute several component ethnic groups, many of which are closely related to ethnic groups in neighboring Eritrea and other parts of the Horn of Africa.
The first documented use of the name "Ethiopia" from Greek name Αἰθίοψ, Aithíops was in the 4th century during the reign of Aksumite king Ezana. There were three ethnolinguistic groups in the Kingdom of Aksum: Semitic, Cushitic, and Nilo-Saharan (ancestors of the modern-day Kunama and Nara). The Kingdom of Aksum remained a geopolitically influential entity until the decline of its capital — also named Axum — beginning in the 7th century. Nevertheless, the core Aksumite civilization was preserved and continued into the successive Zagwe dynasty. By this time, new ethnic groups emerged – the Tigrayans and Amharas. During the Solomonic period, the latter established major political and cultural influence in the Horn of Africa.In the Late Middle Ages, Muslim states were established, including the Sultanate of Ifat, and its successor the Adal Sultanate. Discontent with territory and religious dominance led to intense war between the Ethiopian Empire, the Christian state (consisting of the Amhara, Tigrayan, Soddo Gurage, and Agaw ethnic groups) and the Muslim state Adal Sultanate (consisting of Semitic-speaking Harari formally known as the Harla people, and the Argobba). During the 1600s, there were large-scale migrations of the Oromo from the south into the highlands and also alongside the Somali into Adal or what was known as "Hararghe" (land of the Hararis).
