How have ethnopolitical landscapes transformed across Africa? The authors of this article analyze how ethnic identities have been influenced by two major socioeconomic revolutions of 19th and 20th century sub-Saharan Africa: cash crops and print technologies. They found that ethnic identities, through the means of politicization and boundary-making, had become more salient and politically relevant in communities where cash crops and print technologies were present. Furthermore, areas with cash crops and subsequent agricultural zones were found to have stricter ethnic boundaries and less interethnic marriage than areas with more print publications.

In an attempt to explain communal conflict, this study investigated how customary institutions (i.e. legislatures, courts, and chiefs) may impact the communal conflict activity of groups in Africa. The authors suggest that customary authorities act as local enforcements to mitigate within-group conflict, therefore a higher number of customary institutions should decrease communal conflict. Using data from 143 politically relevant ethnic groups, the authors showed support for their hypothesis and demonstrated marginal support that more inclusive customary institutions would be associated with less communal conflict.

The preindustrial family structure instilled family members with values that passed through generations and impact today's political attitudes and policies. Three studies show that ancestral kinship structure predicts right-wing cultural attitudes and, among those less engaged in politics, left-wing economic attitudes (though controlling for the country of residence removes this prediction). Stronger country-level ancestral kinship strength also increases anti-LGBT policies and welfare spending. This work indicates that political beliefs are rooted in the value systems and familial institutions created by our forebears.

This paper tests "theories which suggest that there are causal-functional relationships between the dependent variables peacemaking and peace stability on the one hand and certain independent variables, such as political complexity, warrior class, warfare objectives, cultural homology and intersocietal ties, on the other hand." Significant relationships were found between the last three independent variables.

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.

Researchers looked at 180 of the 186 societies in the SCCS for changes over time in lineage systems. The goal was to estimate the frequency of transitions away from and to matriliny cross-culturally, as well as explore the potential causes of these patterns / transitions. The study focused on two overarching research questions: 1. How common are transitions away from matriliny and how often do ‘reverse transitions’ to matriliny occur? 2. What causes transitions to or from matriliny? Overall, the study found that transitions away from matriliny have been quite common within the time frames covered by the ethnographic samples available, while transitions from another system to matrility have been rare. In answering the second question, the researchers report the highest correlation is between subsistence transitions (towards pastoralism, intensive agriculture, or a market economy) and lineage transitions (away from matriliny) as well as between higher levels of social complexity (measured by stratification, slavery, and population size) and lineage transitions (away from matriliny).

This paper examines the relationship of productive variation in land between ethnic groups to determine if an increased range of producible goods will increase trade, thus decreasing language diversity between neighboring groups. The author initially found that high-variation in land production lessened the diversity of language between ethnic groups in that area. To further test this correlation, the author found that high-productive variation increased trade and exogamous marriage and decreased inter-ethnic conflict. Based on these findings, the author suggests that neighboring ethnic languages co-evolved through the economic benefit of inter-ethnic trade and social interaction.
