I want to know the answer to the following question:
Why was Dinuzulu kaCetshwayo imprisoned on the island?
All the background I'm provided with is that "Napoleon was imprisoned there in exile by the British, as were Dinuzulu kaCetshwayo (for leading a Zulu army against British rule) and more than 5,000 Boers taken prisoner during the Second Boer War.". Is that enough to answer the question?
