This article provides an overview of the theoretical and empirical contributions made by scholars of ethnic politics in Africa. I first discuss the definitions and measures of ethnic politics most commonly used. I then review the main explanations of the prevalence of ethnic politics. The following sections discuss the consequences of politicized ethnicity, variation in ethnic politics, and the relationship between ethnicity and other social identities, such as national identity. I conclude with some remarks about existing gaps and promising future avenues of research.
