Which country was Julius Nyerere first Prime Minister?

Julius Kambarage Nyerere (April 1922 – 14 October 1999) was a Tanzanian anti-colonial activist, politician, and political theorist. He governed Tanganyika as its Prime Minister from 1961 to 1963 and then as its President from 1963 to 1964, after which he led its successor state, Tanzania, as its President from 1964 until 1985. He was a founding member of the Tanganyika African National Union (TANU) party and later a member of the Chama Cha Mapinduzi party. Ideologically an African nationalist and African socialist, he promoted a political philosophy known as Ujamaa.

Julius Kambarage Nyerere was born on 13 April 1922 in Mwitongo, an area in the town of Butiama in Tanganyika's Mara Region. He was one of 26 surviving children of Nyerere Burito, the chief of the Zanaki people. As the son of a chief he was exposed to African-administered power and authority, and living in a compound gave him an appreciation for communal living that would influence his later political ideas.
