During the nineteenth-century European drive for possessions in Africa and Asia, people justified colonialism in various ways, claiming that it Christianized the heathen or civilized the savage races or brought everyone the miraculous benefits of free trade. Now, with Africa, a new rationalization had emerged: smashing the "Arab" slave trade. At this early stage of his career, however, the future Leopold II did not try to cloak his ambitions with such rhetoric. For him, colonies existed for one purpose: to make him and his country rich. "Belgium doesn't exploit the world," he complained to one of his advisers. "It's a taste we have got to make her learn."
