Foreign relations of Tanzania
Tanzania's first president, Julius Nyerere also was one of the founding members of the Non-Aligned Movement, and, during the Cold War era, Tanzania played an important role in regional and international organisations, such as the Non-Aligned Movement, the front-line states, the G-77, and the Organisation of African Unity (OAU) (now the African Union). One of Africa's best-known elder statesmen, Nyerere was personally active in many of these organisations, and served chairman of the OAU (1984–85) and chairman of six front-line states concerned with eliminating apartheid in Southern Africa.
