Sultanate of Zanzibar

The Sultanate of Zanzibar (Swahili: Usultani wa Zanzibar, Arabic: سلطنة زنجبار, romanized: Sulṭanat Zanjībār), also known as the Zanzibar Sultanate, was an East African Muslim state controlled by the Sultan of Zanzibar, in existence between 1856 and 1964. The Sultanate's territories varied over time, and after a period of decline, the state had sovereignty over only the Zanzibar Archipelago and a 16-kilometre-wide (10 mi) strip along the Kenyan coast, with the interior of Kenya constituting the British Kenya Colony and the coastal strip administered as a de facto part of that colony.
