Zanzibar is a famous trade town in Tanzania in Africa. For many centuries, traders would trade food, spices and exotic animals. Traders came from round the world, including Spain and Portugal. Later, it became an important city for trading slaves. Now, with its past behind it, it has transformed into a beautiful coastal resort town, including a Hilton hotel. Zanzibar is where Portuguese and the native African languages mixed to form Swahili, which is still spoken along much of the coast of Eastern Africa.
