The goal of the paper is to demonstrate how international slave trade spread the institution of slavery throughout Africa, resulting in long-term effects of the continent’s income and political centralization. The author first estimated the travel time to slave ports from each society in the Ethnographic Atlas to determine predicting factors for the adoption of slave trade in African societies. The author reported that societies with high exposure to slave capture in the past were more likely to have the custom of slavery and the custom of polygyny. The author further suggested that slavery institutions emerged in West Africa through local, politically centralized aristocratic systems while emerging in East Africa through the preservation of wealth within the nuclear family over generations.

This article investigates commonly accepted theories that purport to explain political centralization and investigate their relevance to sub-Saharan Africa. The leading ideas for the formation of political centralization using a worldwide sample include population density, inter-state warfare, and trade. However, the authors reported these factors are not predictive of the sub-Saharan Africa sample. The authors suggest that the lack of agricultural productivity in sub-Saharan Africa may have stunted population density therefore inhibiting political centralization and that Africa’s poor economic performance is, in part, due to lack of political centralization.

In this study, the authors draw from intensity theory and combine previous research from the fields of behavioral ecology, economics, and social evolution to analyze drivers in the emergence and persistence of inequality across the world. They propose that environmental heterogeneity and circumscription (the difficulty of moving and establishing oneself in a new environment relative to remaining in the current one) play a significant role in the stratification of societies. Their results indicate that situations arise from various environmental conditions and levels of circumscription that may result in an individual giving up autonomy for material gain, thus favoring inequality.

From 1600 to 1900, the ratio of men to women enslaved and exported in the African slave trade was roughly 181:100 – in other words, nearly two men were enslaved for every woman. It has long been theorized that this historical disparity continues to affect Africa’s cultural and political systems. In this article, the authors examine the impact of temporary gender imbalances caused by the slave trade on female political participation in modern African nation-states. They find that female political participation (measured using national voting records from 2011–2018) is higher in parts of Africa that lost a greater number of individuals to the slave trade, but only among non-patrilineal ethnic groups.

Lowes and Nunn test the theory that the transatlantic and Indian Ocean slave trades of the thirteenth to nineteenth centuries prompted a shift towards matrilineal kinship systems throughout sub-Saharan Africa. Controlling for ecological variables commonly thought to affect kinship structure (including ruggedness of terrain, suitability for agriculture, etc.), the authors find a significant correlation between the number of people enslaved from a given ethnic group, and the tendency of that group towards a matrilineal kinship system. Polygyny was also identified as a statistically significant characteristic of communities most impacted by the slave trade.
