The Tanganyika African National Union (TANU) was the principal political party in the struggle for sovereignty in the East African state of Tanganyika. The party was formed from the Tanganyika African Association by Julius Nyerere in July 1954 when he was teaching at St. Francis' College. From 1964 the party was called the Tanzania African National Union. In January 1977 the TANU merged with the ruling party in Zanzibar, the Afro-Shirazi Party (ASP), to form the current Revolutionary State Party or Chama Cha Mapinduzi (CCM). The policy of TANU was to build and maintain a socialist state aiming towards economic self-sufficiency and to eradicate corruption and exploitation, with the major means of production and exchange under the control of the peasants and workers.
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.
Abeid Amani Karume was the first President of Zanzibar. He obtained this title as a result of a revolution which led to the deposing of Sir Jamshid bin Abdullah, the last reigning Sultan of Zanzibar, in January 1964. Three months later, the United Republic of Tanzania was founded, and Karume became the first Vice President of the United Republic with Julius Nyerere of Tanganyika as president of the new country. He was the father of Zanzibar's former president, Amani Abeid Karume.

The Articles of Union of Tanganyika and Zanzibar of 1964 is the main foundation of the Constitutions of the United Republic of Tanzania of 1977 and the Zanzibar Revolutionary Government of 1984. The Articles of the Union were signed on April 22, 1964, by the Founders of the Union, Julius Nyerere and Abeid Amani Karume and agreed in 11 matters which later increased to over 22 and are the source of tension and dispute between mainland Tanzania mainland and Zanzibar. See Uamsho movement. The original Articles of Union which contain both Signatures from Nyerere and Karume are yet to be found.
The Chama Cha Mapinduzi is the dominant ruling party in Tanzania and the second longest-ruling party in Africa, only after the True Whig Party of Liberia. It was formed in 1977, following the merger of the Tanganyika African National Union (TANU) and the Afro-Shirazi Party (ASP), which were the sole operating parties in mainland Tanzania and the semi-autonomous islands of Zanzibar, respectively.
Zanzibari independence is a political ambition of some political parties, advocacy groups, and individuals of Zanzibar, a semi-autonomous region territory within Tanzania, to become an independent sovereign state.
