Combining individual data from Afrobarometer (2005-2023) with the pre-colonial location of ethnic homelands, I find a significant effect of exogenously defined borders on current attitudes. Difference-in-differences estimates show that individuals from majority segments within partitioned groups exhibit lower trust, weaker national identification, and perceptions of discriminatory political systems. Overall, the findings highlight how colonial borders persistently deteriorate social cohesion.engAfrobarometerColonial partitioningEthnicityTrustIdentityPolitical discriminationmaster thesis203958713
