German East Africa / Tanganyika · Haiti and Kenya independence
German East Africa was governed from Dar es Salaam. The Maji Maji rising of 1905–07 was crushed with famine and great loss of life. After the First World War, Britain governed the territory as Tanganyika under a League of Nations mandate that limited settler land grants. Julius Nyerere’s TANU led Tanganyika to independence on 9 December 1961. It united with Zanzibar in 1964 as Tanzania.

German East Africa · WWI
In German East Africa, Lettow-Vorbeck conducted a four-year fighting retreat that tied down 130,000 imperial troops (Ch. 9). Africans bore a terrible cost: porters died in the hundreds of thousands, while requisition brought famine. The peace partitioned the territory into League mandates, Tanganyika under Britain and Ruanda-Urundi under Belgium. Empire had a new name, but continued.

Tanzania · Decolonization of Africa
Tanganyika won independence peacefully in 1961 and joined Zanzibar to form Tanzania in 1964. Julius Nyerere, “Mwalimu,” the teacher, was the era’s most respected leader. In the 1967 Arusha Declaration he set out Ujamaa, an honest homegrown socialism founded on self-reliance and equality. Its economic results were poor, but his nation-building held a plural country together where others fractured. Nyerere also did something rare among his contemporaries: he handed power on voluntarily.
| British-ruled — the opening position | |
| Independent Africa |
