Tsavo is a region of Kenya locate at the crossing of the Uganda Railway over the Tsavo River, close to where it meets the Athi River. Until the British put an end to the slave trade in the 19th century, Tsavo was continually crossed by caravans of Arab slavers and their captives. Many of the victims dropped dead by the way and were eaten by lions. In this manner, some lions of Tsavo acquired a taste for human flesh.
