70 years have passed since Bulgaria was admitted as a member of the United Nations (UN).

Bulgaria was admitted as a full member of the UN on December 14, 1955, with a resolution of the General Assembly. Admission marked the country's exit from international isolation after World War II and laid the foundations for the restoration of international authority.

The admission was approved with 50 votes in favor, 2 against (China, Cuba), and 5 abstentions (Greece, Netherlands, Philippines, USA, Dominican Republic). On the initiative of the Soviet Union, 16 countries were admitted.

Secretary-General Dag Hammarskjöld sent a congratulatory telegram. A public meeting was held in Sofia, and Dr. Petar Vutov became Bulgaria's first permanent representative to the UN.

Bulgaria participates in the work of the UN to promote multilateralism, trust, and security. For 70 years, it has been a non-permanent member of the Security Council (3 times), President of the Council (3 times), and President of the General Assembly (1 time).

In 2016, Irina Bokova and Kristalina Georgieva were candidates for Secretary-General. António Guterres was elected and re-elected in 2021.

The UN marked 80 years since the signing of the Charter. 193 states are members of the organization.
