Following the 1989 Senegal-Mauritania conflict, 50,000 black Mauritanians were forcibly expelled into the neighboring state of Senegal. These Mauritanians belong to multiple different ethnic groups that are also present in Senegal, though to varying degrees of social salience. This paper seeks to assess how different ethnic groups have experienced integration into Senegal, and analyze what factors – such as language, family, and finances – have influenced their ability to belong within the Senegalese community. In the thirty years since the conflict, these migrants and refugees have had several influences on their integration process, including kinship ties, ethnic ties, history of discrimination, and government and administrative influence. Starting with a detailed history of the conflict and a background into kinship and ethnic research in the region, I perform thematic analysis on qualitative interviews that I conducted with Mauritanian migrants and refugees who currently reside in Senegal to understand the individual and contextual drivers of integration and belonging. This study has broad implications for the future of refugee policy in West Africa, and scholars and policymakers can incorporate lessons about how refugees of different backgrounds were able to feel at home in a neighboring nation.
