“MISSIONARIES and travellers report that human flesh was offered for sale at markets ‘in many parts of Nigeria’. According to clergyman and archdeacon George Basden, who spent more than 30 years in the country, in some southern regions, it had a well-established market price and was sold much like any other commodity; it usually came from war captives, kidnapped strangers, and purchased or bartered slaves.While travelling near Onitsha around the year 1900, Basden found out that his servants and carriers had all repeatedly eaten human flesh. Once they were sure that he bore them no ill will, they talked freely about the custom, including their preferred body parts. He noted that they were ‘quite good-natured folk’, with one of them later becoming ‘a much-respected evangelist’.”
