As the Atlantic slave trade diminished over the course of the nineteenth century, Europeans began to look at Africa in new ways—as a source of raw materials, as an opportunity for investment, as a market for industrial products, as a field for exploration, and as an opportunity to spread Christianity. But it was not until the last quarter of the nineteenth century that Europeans showed much interest in actually acquiring territory and ruling large populations in Africa. Source 18.1, from a late nineteenth-century French board game, illustrates the widespread interest in the growing missionary enterprise in Africa as well as in the celebrated adventures of the intrepid explorers who penetrated the dangerous interior of the continent. This game, featuring the travels of David Livingstone and Henry Stanley, enabled ordinary Europeans to participate in exciting events in distant lands. Livingstone (1813–1873) was a British missionary and explorer of Central Africa whose work in exposing the horrors of the Arab slave trade gave him an almost mythic status among Europeans. Stanley (1841–1904), a British journalist and explorer, gained lasting fame by finding Livingstone, long out of touch with his homeland, deep in the African interior.
