Hugh Lofting
In his book for children "Doctor Dolittle's Post Office" (1923), Hugh Lofting created the West African kingdom of "Fantippo", ruled over by a king named Koko. Before his encounters with Dolittle, the fictional King Koko had sometimes made war on others and had sold some of his prisoners as slaves. The main stated purpose of the British in the Anglo-Aro War of 1901–1902 was to suppress the slave trade still being carried on by some African states in what is now Nigeria.
