In this study, the authors empirically assess the relationship between precolonial centralization and the implementation of modernization programs by African governments. Their findings indicate that current African countries tend to have better provisioning of public goods (including better access to education, healthcare, and infrastructure) when their ethnic groups' precolonial institutions were more centralized.

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.

The author presents a comprehensive study on the prevalence, presentation, and motivation of the "ultimate coercive sanction": capital punishment, or the "death penalty." He begins by examining capital punishment across all 53 cultures for which data was present in the Probability Sample Files, and finds that capital punishment is overwhelmingly present. After discerning some general trends, the author examines how capital punishment presents itself across different kinds of political systems, and uses the results to voice support for various theories on why the capital punishment is practiced. The study concludes by stating that the capital punishment may be something that human society may never be truly rid of, but greater societal stability may be able to reduce its prevalence.

The researchers test the relationship between political complexity among African pre-colonial ethnic institutions and contemporary economic performance (using light-density data as a proxy). Their tests yield a robust positive association even after controlling for multiple alternative geographic, cultural, and economic variables, which they interpret as underscoring the ongoing importance of ethnic-specific institutions in shaping economic activity in contemporary Africa.

The author analyzes 440 Sub-Saharan African societies to test whether trade across ecologically diverse zones is predictive of degree of state centralization (state capacity or strength of state) in pre-colonial Africa. The author finds that diverse ecology is predictive of state capacity and that trade supports class stratification. The author also emphasizes the importance of historical contingency and ethnographic data consultation in understanding mechanisms in individual cases.

The authors of this study examine the relationships between historical exposure to Islamic kingdoms and current economic, medical, and educational development in Africa. They predict that ethnic groups that were previously ruled by Islamic states or chiefdoms will have worse outcomes today, theorizing that these worse outcomes would be not as a result of an inherent characteristic of Islam or Islamic kingdoms themselves but rather decreased investment by colonial states or missions. Their results lend some support to their hypotheses, and particularly to the predictions that Christian missions and colonial states would not be able to penetrate areas under Islamic influence as easily as other regions.

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.

In this article, the authors seek to understand the trajectory of traditional political institutions in Africa and ask how these institutions have changed, if at all, due to colonial interference. They note that "institutions connect the past with the present", though the study of political institutions over time is often overlooked in discussions of institutional persistence and change despite their value to key components of governance and social stability. Thus, these authors investigate whether today's African institutions remain akin to their precolonial, institutional ancestors, and whether colonial governance strategies of indirect or direct rule employed by the British and French have impacted their persistence. They find evidence to support the endurance of traditional institutions in former British colonies (upward trend), whereas evidence for institutional destruction for former French colonies (downward trend).

This study examines socio-economic predictors of political complexity. Findings suggest that class stratification is the most significant predictor of political complexity.

This article examines the evolution of games, particularly the way the complexity of games is affected by political organization, demographics, social differentiation, and religious differentiation.
