According to the book written by Lovise Aalen,
Most governments in Africa, seeing the political mobilisation of ethnicity as a threat, have rejected the use of ethnic differences as an explicit basis for political representation. The one prominent exception is Ethiopia, which since 1991 has imposed a system of ethnic-based federalism that offers each ethnic group the right of ‘self-determination’. However, currently we are experiencing violence here and then in Ethiopia due to ethnic difference. How scholars see this scenario?
