Show moreNear the coast of equatorial Africa, separated from the continent by a canal some 50 kilometres long, is the island of Zanzibar (Unguja). It is the largest of the coral islands of the eastern coast of Africa and forms part of a coral reef that extends from the near island of Pemba (al-khudra, the green, or emerald island), to the north, as far as the island of Mafia to the south. It constitutes a type of extraneous coastline to the continent. The city of Zanzibar is situated to the west of the island and its port, one of the best of Africa, allows deep anchorage for the docking of the ships. Zanzibar has always been strategically important due to two fundamentally important points: its proximity to the continent and the monsoons. The regular recurrence of these latter allows continuous contacts with India, the Red Sea and the Persian Gulf; while the closeness of Zanzibar to the coast places it in an ideal position for commerce between the interior of the African continent and the Indian Ocean.
