2008 Zanzibar power blackout 2008 Zanzibar power blackout The 2008 Zanzibar Power blackout was an extensive power outage on Zanzibar, Tanzania. A similar and longer event happened in Zanzibar in 2009. The island was without power for more than three months. During May and June 2008, Zanzibar suffered a period of almost one month without mains electricity due to a grid failure which left the entire island dependent on alternative methods of electricity generation (mainly diesel generators). Power failed on 21 May 2008 after a wide-area grid failure across the Tanzanian network was followed by a power surge which damaged the submarine interconnector cable
History of Zanzibar received its independence from the United Kingdom as a constitutional monarchy under the Sultan. This state of affairs was short-lived, as the Sultan and the democratically elected government were overthrown on 12 January 1964 in the Zanzibar Revolution led by John Okello, a Ugandan citizen who organized and led the revolution with his followers on the island. Sheikh Abeid Amani Karume was named president of the newly created People's Republic of Zanzibar and Pemba. Several thousand ethnic Arab (5,000-12,000 Zanzibaris of Arabic descent) and Indian civilians were murdered and thousands more detained or expelled, their property either confiscated or destroyed.
