The Tigray are the largest ethnic group in the Ethiopian province of Tigray and in the Eritrean nation. The Tigray have not been as thoroughly studied as their culturally similar neighbors, the Amhara, with whom they share an "imperial" heritage. The Aksumite Kingdom had its seat in Tigray territory. There are approximately 2,000,000 Tigray, primarily divided between Tigray and Eritrea. Drought, civil war, and resettlement make precise estimates impossible. Tigrenna is Semitic and more closely related to the liturgical language Ge'ez than is Amhara. All three languages are written using a common script.
