But the name of one place on the coast of Africa has long captured people's imagination: Zanzibar, also know as the spice island. For centuries, merchants of of all colours and creeds came to the island off the Tanzanian mainland on wooden vessels - and each of them left their own mark on the island.

Professor Abdul Sherif from the Zanzibar Ocean Research Institute explains that Arabs were targeted in particular because 'they w
