Article dans une revue: The partition of German Togoland after World War I provides a natural experiment to test the impact of British and French colonization. Using data of recruits to the Ghanaian colonial army 1908–1955, we find that literacy and religious affiliation diverge at the border between the parts of Togoland under British and French control as early as in the 1920s. We partly attribute this to policies towards missionary schools. The divergence is only visible in the South where educational and evangelization efforts were strong. Contemporary survey data show that border effects that began in colonial times still persist today.
