Weber's concept of charisma has not been empirically useful to sociology even though it has influenced sociological thinking considerably. The reason is that Weber dealt with charisma more as a psychological than a social phenomenon. The concept can be useful, however, in the analysis of social change if the focus of attention is concentrated on the social context within which charisma develops rather than on charisma or charismatics. Utilizing the example of modern African leadership in Tanganyika, charisma appears in situations where (a) leaders formulate inchoate sentiments deeply held by masses; (b) the expression of such sentiments is seen as hazardous; (c) success—as defined by the relevant social groups—is registered.
