Chaka kills Noliwe to buy kingship
The diviner Isanusi tells Chaka that the medicines securing his kingship require the blood of the person he loves most. Chaka chooses to kill Noliwe, the woman he loves and the sister of his patron Dingiswayo, by his own hand, and so trades love for power. From then on he kills more and more people, including his soldiers' mothers and his own mother, Nandi. He is finally stabbed by his half-brothers Dingana and Mhlangana, and Isanusi returns only to collect what he is owed.
