This article discusses David van Reybrouck’s history of Congo. The focus is on violence and there is special attention for the period of the Congo Free State, 1885-1908, under king Leopold. A comparison is made between Van Reybrouck’s views and those of Adam Hochchild. It is concluded that the former passes a milder judgment on the actions of Leopold’s troops than the latter, while he also presents a more diversified account. Both authors, however, reject the label of genocide for Leopold’s ‘rubber terror’. The article concludes with some reflections on the concept of genocide, proposing to replace it with organized murder.
