The First Non-Aligned Summit was held in Belgrade in:

1961

The correct answer is option (4) - 1961

The Afro-Asian conference held in the Indonesian city of Bandung in 1955, commonly known as the Bandung Conference, marked the zenith of India’s engagement with the newly independent Asian and African nations. The Bandung Conference later led to the establishment of the NAM. The First Summit of the NAM was held in Belgrade in September 1961. Nehru was a co-founder of the Non Alignment Movement.

The roots of NAM went back to the friendship between three leaders — Yugoslavia’s Josip Broz Tito, India’s Jawaharlal Nehru, and Egypt’s leader Gamal Abdel Nasser — who held a meeting in 1956. Indonesia’s Sukarno and Ghana’s Kwame Nkrumah strongly supported them. These five leaders came to be known as the five founders of NAM.
