We examine whether shared collective experiences help build a national identity, by looking at the impact of national football teams’ victories in sub-Saharan Africa. We find that individuals surveyed in the days after an important victory of their country’s national team are 37 percent less likely to identify primarily with their ethnic group, and 30 percent more likely to trust other ethnicities, than those interviewed just before. Crucially, national team achievements also reduce violence: countries that (barely) qualified to the Africa Cup of Nations experience less civil conflict (9 percent fewer episodes) in the following months than countries that (barely) did not.

I examine empirically the role of historical political centralization on the likelihood of contemporary civil conflict in Sub-Saharan Africa. I combine a wide variety of historical sources to construct an original measure of long-run exposure to statehood at the sub-national level. I then exploit variation in this new measure along with geo-referenced conflict data to document a robust negative relationship between long-run exposure to statehood and contemporary conflict. From a variety of identification strategies, I provide evidence suggesting that the relationship is causal. I argue that regions with long histories of statehood are better equipped with mechanisms to establish and preserve order. I provide two pieces of evidence consistent with this hypothesis. First, regions with relatively long historical exposure to statehood are less prone to experience conflict when hit by a negative economic shock. Second, exploiting contemporary individual-level survey data, I show that within-country long historical statehood experience is linked to people's positive attitudes toward state institutions and traditional leaders.
