1963-1964: independence and union
Zanzibar achieved independence in December 1963, underwent a January 1964 revolution, and united with Tanganyika in April 1964.[1]
· Agreement
Union of Zanzibar and Tanganyika, 1964
Following a revolution, Zanzibar united with Tanganyika to form Tanzania under a semi-autonomous arrangement.
1964-1977: erosion of autonomy
The originally semi-autonomous Zanzibari government structure was progressively weakened through constitutional amendments up to 1977.[2]
Modern autonomist and independence movements
The CUF and ACT-Wazalendo seek greater autonomy; the distinct Uamsho movement seeks full independence.[3]

Claim: Zanzibar achieved independence as a Commonwealth member on 10 December 1963; in January 1964, the Zanzibari government was overthrown in a revolution and a republic proclaimed. On 22 April 1964, Julius Nyerere and Abeid Amani Karume signed the Articles of Union, and on 26 April 1964, Zanzibar joined Tanganyika to form the United Republic of Tanzania. This bundle does not narrate the January 1964 revolution's violence in detail.

Claim: The Articles of Union established a two-tier governmental structure with a semi-autonomous Zanzibari government, including its own parliament and president (who also served as Vice President of Tanzania), alongside the federal Union government; though intended as an interim arrangement lasting about a year, this constitutional structure remained in place until 1977, during which period a series of amendments progressively strengthened the ruling party's (TANU's) authority and reduced Zanzibar's autonomy.

Claim: The Civic United Front (CUF), a liberal autonomist party with its strongest support in Zanzibar's Unguja and Pemba islands, has sought greater autonomy for Zanzibar within Tanzania rather than independence, and formed a coalition government with the ruling Chama Cha Mapinduzi (CCM) in 2020 following disputed elections; the Alliance for Change and Transparency-Wazalendo (ACT-Wazalendo), currently the main Zanzibari opposition party, also joined a coalition with the CCM in December 2020. By contrast, Uamsho, an Islamist movement led by Farid Hadi Ahmed, explicitly seeks full independence for Zanzibar, and has reportedly gained support among former CUF supporters disenchanted with that party's 2020 coalition decision.
