The adoption of ethnic federalism in Ethiopia was closely related with the problem of creating a state structure that could be used as instrument of managing the complex ethno-linguistic diversity of the country. Ethiopia is a multinational country with about 85 ethno-linguistic groups and since the 1960s, it suffered from ethno-regional conflicts. The book considers multiple governance and state factors that could explain the difficulties Ethiopian federalism faces to realise its objectives. These include lack of political pluralism and the use of ethnicity as the sole instrument of state organisation. will be of interest to students and scholars of federal studies, ethnic conflict and regionalism.
