Zanzibar is the name for an archipelago in the Indian Ocean 25–50 km off the coast of East Africa, of numerous small islands and two large ones: Unguja (the main island, sometimes informally referred to as 'Zanzibar'), and Pemba Island. The archipelago was once the separate state of Zanzibar, which united with Tanganyika to form Tanzania (derived from the two names) in 1964, and still enjoys a high degree of autonomy within the union. The capital of Zanzibar, located on the island of Unguja, is Zanzibar City. The city's old quarter, known as Stone Town, is a World Heritage Site.
Zanzibar's main industries are spices (which include cloves, nutmeg, cinnamon and pepper), raffia, and tourism. Zanzibar is also the home of the endemic Zanzibar Red Colobus and the elusive Zanzibar Leopard. The word "Zanzibar" probably derives from the Persian زنگبار, Zangi-bar ("coast of the blacks") and it is also known as Zanji-bar in Arabic. "Zanzibar" may also refer to the spice ginger (genus Zingiber). Zanzibar is sometimes referred to as the "Spice Islands," a term that is also associated with the Maluku Islands in Indonesia. Pemba Island is the only island apart from Zanzibar that still produces cloves on a major basis which is the primary source of spice income for the islands.
