Zanzibar Revolution in the context of "Decolonisation of Africa"

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 place 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.

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, revolutionaries, led by the African Afro-Shirazi Party, overthrew the mainly Arab government. Jamshid bin Abdullah, the last sultan, was deposed and lost sovereignty over Zanzibar, marking the end of the Sultanate, and resulted in the massacre of tens of thousands of Arabs. It was also involved in the shortest war in history, the Anglo-Zanzibar War, which lasted 38 minutes.

Zanzibar City or Mjini District, often simply referred to as Zanzibar (Wilaya ya Zanzibar Mjini or Jiji la Zanzibar in Swahili), is one of two administrative districts of Mjini Magharibi Region in Tanzania. The district covers an area of 15.4 km (5.9 sq mi). The district is comparable in size to the land area of Nauru. The district has a water border to the west by the Indian Ocean. The district is bordered to the east by Magharibi District. The district seat is in Stonetown. The city is the largest on the island of Zanzibar. It is located on the west coast of Unguja, the main island of the Zanzibar Archipelago, north of the much larger city of Dar es Salaam across the Zanzibar Channel. The city also serves as the capital of the Zanzibar Urban/West Region. In 2022 its population was 219,007.

Zanzibar City comprises two main parts, Stone Town and Ng'ambo (literally: "The Other Side"); the two areas were historically divided by a creek since filled in, with the street on the Stone Town side of the creek originally called Creek Road but later renamed to Benjamin Mkapa Road. Stone Town is the historical core of the city, the former capital of the Zanzibar Sultanate; because of its unique architecture and culture, it was declared a UNESCO World Heritage Site in 2000. Ng'ambo is a much larger, modern area that developed around Stone Town after the Zanzibar Revolution, with office buildings and large apartment blocks such as those of the Michenzani neighbourhood. Zanzibar City is served by a number of international and domestic airlines via Abeid Amani Karume International Airport.

The Afro-Shirazi Party (ASP) was an African nationalist and socialist Zanzibari political party formed between the mostly Shirazi Shiraz Party and the mostly African Afro Party.

In the 1963 Zanzibari general election, the ASP claimed 13 seats and the majority of votes cast, yet the election ended up favouring the Zanzibar Nationalist Party and Zanzibar and Pemba People's Party alliance who collectively claimed 18 seats. Unsatisfied with such unfair representation in parliament, the ASP, headed by Abeid Karume, collaborated with the Umma Party to begin the Zanzibar Revolution on 12 January 1964. The revolution overthrew the Sultanate of Zanzibar and established the People's Republic of Zanzibar, ruled by Abeid Karume. Following the establishment of the republic, the ASP banned the previous ruling parties—the Zanzibar Nationalist Parity and the Zanzibar and Pemba People's Party. On 5 February 1977, the party joined with the Tanganyika African National Union (TANU) to form Chama Cha Mapinduzi (CCM).

Jamshid bin Abdullah Al Busaidi, GCMG (Arabic: جمشيد بن عبد الله البوسعيدي; 16 September 1929 – 30 December 2024) was a Zanzibari royal who was the last reigning Sultan of Zanzibar. He was deposed in the Zanzibar Revolution, after the United Kingdom gave up its British protectorate.

In January 1964, during and following the Zanzibar Revolution, Arab residents of Zanzibar were victims of targeted violence committed by the island’s majority Black African population. Arabs were mass murdered, raped, tortured and deported from the island by Black African militiamen under the Afro-Shirazi Party and Umma Party. The exact death toll is unknown, although scholarly sources estimate the number of Arabs killed to be between 13,000 and more than 20,000, around a quarter of the Arab population. It has been described by some, including a number of scholars, as an act of genocide.

Omani and Arab elites had dominated the society of the island for more than two hundred years, both politically and economically. The uprising against the ethnic Arabs (and Indians) has been overlooked by the majority and the massacres remain largely undiscussed and outside the public eye in terms of official histories. The Zanzibar Revolution is publicly celebrated on its anniversary as an uprising against slavery and oppression, although slavery in Zanzibar had already been abolished almost a century before. Regardless, the massacres are either downplayed or not discussed at all.
