Zanzibar is an archipelago made up of Unguja (informally known as Zanzibar), Pemba Islands and about 51 surrounding small islets.
Zanzibar is a semi-autonomous part of the United Republic of Tanzania. It is located in the Indian Ocean, about 25 miles (30 km) from the Tanzanian coast, and 6° south of the equator.
The name is a combination of two Arabic words, "Zenj" = black and "barr" = land, resulting in the title "Land of the Blacks". Pemba is named Al-khudra = "The Green Island".
