The Rwandan refugee camps in Tanzania witnessed the marriages of very young adolescents: girls as young as 13–14 married boys of 14–15 years, boys they often did not even know. These marriages usually did not last very long; after a few months many girls were forced to leave—sent away by their husband. People of both sexes and all ages, when asked about the problems in the camp, would always mention these child marriages as one of the biggest problems. They were worried not only about the loss of respect for Rwandan culture and traditional values but also about the future of the marriages and what would become of the children. This article is not based on extensive research into child marriages, but the author was able to interview a number of young people who had got married in the camps, and to collect information and the opinions of other people on these and other cases. Rather than describing marriage customs and wedding ceremonies in Rwanda, and comparing them with what took place in the refugee camps, the article aims to show the impact of (civil) war, the consequent poverty and the destruction of social structures on a community, in order to show how in these circumstances behaviour can change radically. Refugees have to build up a new life in a camp, and the new ‘society’ is likely to be different from the one they came from, with different rules and changed values. Among various examples of deviant behaviour child marriages were the most remarkable.
