What is the theme in King Leopold's Ghost by Adam Hochschild?

Another theme in the book is manipulation of the media. The book suggests that Leopold was a master of media manipulation. While his administration was busy plundering the Congo and committing routine acts of murder, slavery and rape, Leopold was promoting himself as a paragon of humanitarianism. Most European and American people of the time felt that colonialism was not only justified but uplifting to native peoples. Leopold used this sentiment to position himself in the public eye as a concerned ruler of a distant colony.
