Third-worldism is a political concept and ideology that emerged in the late 1940s or early 1950s during the Cold War and tried to generate unity among the countries that did not want to take sides between the United States and the Soviet Union.
[1] Third-worldism was connected to new political movements following the decolonization and new forms of regionalism that emerged in the erstwhile colonies of Asia, Africa, and the Middle East as well as in the older established states of Latin America, including pan-Arabism, pan-Africanism, pan-Americanism and pan-Asianism.
[2] The first period of the third-worldist movement, that of the "first Bandung Era", was led by the Egyptian, Indonesian and Indian heads of states such as Nasser, Sukarno and Nehru.
[2] Third World solidarity is a key tenet of Third Worldism, emphasizing unity and cooperation among countries and peoples of the Global South in the struggle against imperialism, colonialism, and neocolonialism.
[3] It embodies the principle of mutual support and shared interests among formerly colonized and oppressed peoples, seeking to address common challenges such as poverty, underdevelopment, and marginalization.
