This paper deals with the theme of the Non-Aligned Movement, with its founding, development, and decline in its influence and power in the world, with particular reference to Yugoslavia's role in this. Josip Broz Tito, Jawaharlal Nehru, Gamal Abdel Nasser, Kwame Nkrumah and Sukarno are considered the founders of the Movement. The Cold War stands out as a period in history that had a great impact on the Movement itself. It shows a cross-section of the most important events at conferences that brought together non-aligned countries and decided which direction the Movement would take, what views it would take, and what needed to be done to preserve independence from the East (USSR) and the West (USA). President Tito remained the most politically active person in the Movement among those countries. Yugoslavia led by Tito had a special role in the Non-Aligned Movement, which was particularly prominent at the 1979 conference in Havana when the USSR's attempt to transport the Movement to the East via Cuba was rejected. The influence and power of the Movement in the world began to decline towards the end of the 1980s, especially in the early 1990s when the Soviet Union collapsed, that is, the end of the Cold War. The Movement after that never reached the power and influence it had in the previous period.
