Political regulation of ethnicity has been a core dimension of state-building in Africa, and a set of different macro-political strategies was applied in African postcolonial states to deal with ethnic heterogeneity. One set of strategies consisted in attempts to completely eliminate political manifestations of ethnicity, violently through genocide (Rwanda, 1994) or mass expulsions of ethnic minorities (Uganda, 1973), consensually through secession of autonomous provinces (Eritrea, 1993; South Sudan, 2005), through legal instruments that ban the political expression of ethnic identity such as party bans, or via coercive variants of assimilation (Rwanda, 2001). An opposing option promoted the formal recognition of ethnicity through consociationalism (Burundi, 2005), ethnic federalism (Ethiopia, 1995), ethnic minority rights (Mauritius), or hegemonic control (apartheid South Africa). Many African countries have instead opted for an informal accommodation of ethnic identity in politics, which combines the pursuit of civic nationalism and ethnic party bans with a de facto recognition of ethnic group rights through informal power-sharing, centripetal institutions, or variants of federalism which shift resources and competencies to subnational levels. The choice of strategies is, however, constrained by how interethnic relations have been shaped in the process of postcolonial state-building. Both strategies of elimination and of formal recognition are applied in ranked societies where one racial or ethnic group managed to take control of the state and in which class corresponded with ethnic affiliation. South Africa, which also belonged to this group, seems to be the only country where a liberal model of civic nation is pursued along with a strong recognition of the country’s diversity in the political and constitutional architecture.
