Using a new expert survey, the authors explore the democraticness of traditional political systems (TPS) in 159 ethnic groups in Africa. Their initial analysis finds that measures of public preference input and political process control are particularly strong contributors to the degree that a society may develop democracy in their TPS. They also find that societies with powerful elders are more likely to be democratic, while more hierarchically organized political systems and those with kings, chiefs, and segmentary lineages are less likely.

The authors of this article evaluate how the legacies of early statehood (i.e., precolonial centralized ethnic groups) in Africa continue to impact democratic governance. They find a positive relationship between early states and support for autocratic rule, especially in former British colonies that were highly centralized prior to colonization. They suggest that the transmission of political and cultural norms play an important role in the support for autocracies.

Using a new measure called "territorial fractionalization" to indicate the extent to which traditional societies are split across current states, the authors of this study propose that fragmentation of ethnic groups and ethnonationalism is key to understanding civil conflict. They find that higher measures of territorial fractionalization significantly predict a higher risk of civil conflict, and that greater increases in territorial fractionalization also predict greater risk of civil conflict. These results hold for a global sample of data from 1945 to 2017, as well as in European and African subsamples dating back to 1886.
