The 1979 United Nations Security Council election was held from 26 October 1979 to 7 January 1980 during the Thirty-fourth session of the United Nations General Assembly, held at United Nations Headquarters in New York City. The General Assembly elected East Germany, Mexico, Niger, the Philippines, and Tunisia, as the five new non-permanent members of the UN Security Council for two-year mandates commencing January 1980. Taking 155 rounds of voting to resolve, it remains the longest Security Council election in history. Additionally, this was the first time Niger was elected and the only time East Germany was elected member of the Council.
