Zanzibar & islands

Zanzibar is not a separate country. It is a semi-autonomous region of the United Republic of Tanzania, with its own president, parliament and government for many local matters. The name Tanzania itself comes from joining Tanganyika and Zanzibar.

A short history

  • Swahili and Arab trade: for centuries the islands were a centre of Indian Ocean trade.
  • The sultanate: from 1840, the Sultan of Oman ruled from Stone Town, and Zanzibar became a separate sultanate in 1861.
  • British protectorate: from 1890 until independence in December 1963.
  • Revolution: in January 1964 the sultan was overthrown.
  • Union: on 26 April 1964, Zanzibar joined Tanganyika to form the United Republic of Tanzania. Union Day is a public holiday.
