What are the factors made Tanzania to adopt one political party system after Independence?

Tanzania adopted a one-party system after independence largely due to the influence of its founding leader, Julius Nyerere, who believed that a single-party system would promote national unity and stability in a diverse society. The country faced various challenges, including ethnic divisions and post-colonial instability, which Nyerere argued could be better managed under a unified political framework. Additionally, the socialist ideals of the ruling party, the Tanganyika African National Union (TANU), emphasized collective decision-making and the need for a cohesive approach to development. This system was intended to avoid the divisiveness and conflict often associated with multi-party politics.
