ガーナ王国
The Republic of Ghana is named after the medieval West African Ghana Empire. The empire became known in Europe and Arabia as the Ghana Empire after the title of its Emperor, the Ghana. The Empire appears to have broken up following the 1076 conquest by the Almoravid General Abu-Bakr Ibn-Umar. A reduced kingdom continued to exist after Almoravid rule end, and the kingdom was later incorporated into subsequent Sahelian empires, such as the Mali Empire several centuries later. Geographically, the ancient Ghana Empire was approximately 500 miles (800 km) north and west of the modern state of Ghana, and controlled territories in the area of the Sénégal River and east towards the Niger rivers, in modern Senegal, Mauritania and Mali.
