The country was gifted with the able leadership of Julius Nyerere. He was such a unifying factor, cutting across regional and tribal boundaries. Such a figure was lacking in Uganda
Nyerere's friendly relations with the governor, Sir Richard Turnbull with whom they always sat and discussed Tanganyika problems also speeded up the transition to self - rule.
The presence of a national language - Kiswahili. Such a language was lacking in Uganda. Luganda that would have worked was unpopular because of Buganda's already elevated position .
Tanganyika being a mandated territory also helped it to achieve independence earlier. Britain was looking after it on behalf of the United Nations and the United Nations was against colonialism.
Britain was thus under pressure from the UN to decolonize (give up) all her colonies.
Tanganyika was also lucky that it lacked tribal and regional parties that were in Uganda and Kenya. Their bickering stalled constitutional advances in their respective countries. For example, the Kikuyu dominated KANU in Kenya and in Uganda; the Democratic Party was predominantly a party for Baganda Catholics.
There were no Settler demands in Tanganyika as the case was in Kenya. The White settlers in Kenya were threatening to snatch independence from Africans. The case was different in Tanganyika. The Tanganyikans were all united under Nyerere.
The close links that existed between the UN and T AND also speeded up the transition to self - rule,
Nyerere had made several visits to New York seeking support for his cause.
Nyerere was never imprisoned or his party banned as the case was in Uganda and Kenya. Kenyatta was
in prison for seven years and his KANU party banned. In Uganda, the Uganda National Congress
(UNC) was banned for organizing riots and demonstrations.
TANU lacked a strong rival. The United Tanganyika Party (UTA) that had tried to challenge it had no serious programme. This made T ANU rapidly become a national party.
Nyerere came from the Zenaki tribe, one of the smallest tribes in Tanzania. Therefore, there were no tribal conflicts and feuds which led to his rise to power.
The trade unions in Tanganyika were stronger than those in Uganda. They therefore prepared people for politics.
