Slave trades, kinship structures and women's political participation in Africa

We study whether present-day women's political participation in sub-Saharan Africa is associated to the temporary gender ratio imbalances caused by the transatlantic and Indian Ocean slave trades, taking into account pre-existing gender norms influenced by kinship structures. To study the interrelatedness between historical exposure to the slave trades, patrilineality and their association to contemporary women's political participation, we use individual-level data for 35,595 women from 28 sub-Saharan African countries from three rounds of Afrobarometer surveys, georeferenced to historical ethnic region kinship and slave trade data. Our findings suggest that a woman's ethnic region historical exposure to the transatlantic slave trade is associated with an increase in her likelihood to vote today, however, only in non-patrilineal ethnic regions. This effect is mitigated in patrilineal ethnic regions, where women have less decision-making power. This paper contributes to the literature on the contemporary sub-national effects of the slave trades and the historical causes of gender gaps in political participation.
