Disarmament Week

Celebrated on 10/24/2026

Quick Fact

Disarmament Week was first observed in 1978 following a UN General Assembly resolution. The week is timed to coincide with the anniversary of the founding of the United Nations, emphasizing the organization's commitment to peace and security.

Origins and Establishment of Disarmament Week

Disarmament Week was established by the United Nations General Assembly in its resolution S-10/2, adopted at the Tenth Special Session on Disarmament in 1978. The session, the first ever devoted entirely to disarmament, recognized the urgent need to halt the arms race and promote disarmament. The resolution called for the week starting on October 24 (United Nations Day) to be observed annually as Disarmament Week, encouraging member states to highlight the dangers of the arms race and promote disarmament efforts.

Evolution and Modern Commemoration

Since its inception, Disarmament Week has evolved to encompass a broader range of disarmament issues, including nuclear, chemical, and biological weapons, as well as conventional arms. The United Nations and its member states organize various events such as conferences, workshops, and educational campaigns to raise awareness. In recent years, civil society organizations have also played a key role, using the week to advocate for disarmament through social media campaigns and public demonstrations. Despite challenges, the week remains a vital platform for promoting peace and security.
