1964
African revolutionaries take over Zanzibar.
They start off by capturing the police station in Zanzibar Town.
Later they fight the rural Arabs who were known as the Manga.
They also then start killing all the Arabs. In particular they would chop of the testicals and penises of the men and shove them in their mouths as well as decapitate other men. They also raped the Arab woman. At the time the word genocide was know as widely used but it was later noted that the events were plain and simply genocide.
The leader of the revolution, John Okello, was a Christian and believed that the bible could teach him anything. He told his followers to kill as many Arabs as possible, with the maximum of brutality.
