The Sultanate of Zanzibar ( sw, Usultani wa Zanzibar, ar, سلطنة زنجبار , translit=Sulṭanat Zanjībār), also known as the Zanzibar Sultanate,
was a state controlled by the
Sultan of Zanzibar, in place between 1856 and 1964. The Sultanate's territories varied over time, and at their greatest extent spanned all of present-day
Kenya

and the
Zanzibar Archipelago off the
Swahili Coast. After a decline, the state had sovereignty over only the archipelago and a 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.
Under an agreement reached on 8 October 1963, the Sultan of Zanzibar relinquished sovereignty over his remaining territory on the mainland, and on 12 December 1963, Kenya officially obtained independence from the British. On 12 January 1964,
Jamshid bin Abdullah, the last sultan, was deposed and lost sovereignty over the last of his dominions, Zanzibar, marking the end of the Sultanate.

Hamoud bin Mohammed to become Sultan, believing that he would be much easier to work with. The British gave Khalid an hour to vacate the Sultan's palace in Stone Town. Khalid failed to do so, and instead assembled an army of 2,800 men to fight the British. The British launched an attack on the palace and other locations around the city after which Khalid retreated and later went into exile. Hamoud was then peacefully installed as Sultan.
That "Zanzibar" for these purposes included the coastal strip of Kenya that would later become the
Protectorate of Kenya was a matter recorded in the parliamentary debates at the time.

In summary, the "Colony of Kenya" referred to the interior lands. The "Protectorate of Kenya" was a coastal strip together with certain islands which remained under the sovereignty of the
Sultan of Zanzibar until the independence of Kenya.
The Colony of Kenya and the Protectorate of Kenya each came to an end on 12 December 1963. The United Kingdom ceded sovereignty over the Colony of Kenya and, under an agreement dated 8 October 1963, the Sultan agreed that simultaneously with independence for Kenya, the Sultan would cease to have sovereignty over the Protectorate of Kenya.

End of the Zanzibar Protectorate and deposition of the Sultan

On 10 December 1963, the Protectorate that had existed over Zanzibar since 1890 was terminated by the United Kingdom. The United Kingdom did not grant Zanzibar independence, as such, because the UK never had sovereignty over Zanzibar. Rather, by the

The various ethnic groups were becoming mixed and the distinctions between them had blurred;

However, the island's Arab inhabitants, as the major landowners, were generally wealthier than the natives;
the major political parties were organised largely along ethnic lines, with Arabs dominating the
Zanzibar Nationalist Party (ZNP) and natives the
Afro-Shirazi Party (ASP).
