The first Non-Aligned Summit was held in 1961.

Background:

Formation of Non-Aligned Movement:
In 1961, leaders from 25 developing countries met in Belgrade, Yugoslavia, to establish the Non-Aligned Movement. These countries were not aligned with either the Western or Eastern Bloc and sought to remain neutral in the Cold War. They wanted to create an independent voice for the developing world and promote global peace and cooperation.

First Non-Aligned Summit:
The first Non-Aligned Summit was held in Belgrade in 1961, where leaders of the member countries discussed issues such as disarmament, decolonization, and economic development. The summit was attended by leaders such as Jawaharlal Nehru of India, Gamal Abdel Nasser of Egypt, and Josip Broz Tito of Yugoslavia.

Outcomes of the Summit:

The principles also emphasized the need for peaceful coexistence and mutual respect among nations.

The summit also led to the establishment of the Non-Aligned News Agencies Pool, which aimed to promote the exchange of news and information among member countries.

In conclusion, the first Non-Aligned Summit was held in 1961, where leaders of developing countries established the Non-Aligned Movement to promote global peace and cooperation.
