Portrait of Sir Brian Urquhart

From the Congo to the Middle East, UN icon Sir Brian Urquhart was at the “centre of formative global events”, Secretary-General António Guterres said in a statement, paying tribute to the legendary staff member who died at the age of 101. Sir Brian Urquhart, who helped guide the UN from its inception through decades of dramatic challenges, was one of the Organization's first staff members. To celebrate his four decades of service, we feature his Character Sketches from UN News, describing his interactions and impressions of world leaders and historical figures.

"In 2020, as the United Nations celebrates 75 years since the Charter’s signing, we have an opportunity to reflect on our shared progress, as well as our common future."

The UN: Innovating for Peace tells the story of a bold and revolutionary United Nations, throughout its history and for the future.

Leaders of the major allied powers of World War II meeting at Yalta in the Russian Crimea

The Dumbarton Oaks Conference of 1944 on establishing an international organization to maintain peace and security left one important issue unresolved: the voting procedure in the Security Council. This was done at Yalta in the Crimea, where Churchill, Roosevelt and Stalin, together with their foreign ministers and chiefs of staff, met in conference. On February 11, 1945, the conference announced that this question had been resolved, and it summoned the San Francisco Conference, where the UN Charter was drafted and signed.

To mark its 75th anniversary in 2020, the United Nations has launched the biggest-ever global conversation - UN75 - on the role of global cooperation in building the future we want. The campaign will initiate dialogues in all settings – from classrooms to boardrooms, parliaments to village halls. The aim is to reach as many people as possible. On 29 January, 10 - 11 am EST, join us for the UN75 Inaugural Dialogue of youth leaders, moderated by UN Secretary-General António Guterres.

Some 700 outstanding young students from 25 countries are meeting in Geneva (8-10 January) to discuss how the power of technology can change the world. Hosted and co-organized by the International Telecommunication Union (ITU) and FerMUN, the Futurecasters Global Young Visionaries Summit focuses on how technologies can be harnessed for progress towards the SDGs. Model United Nations (MUN) simulations are a popular way to learn about the UN. More than 400,000 students worldwide participate every year in MUN at all educational levels – from primary school to university.

International days are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.

The United Nations is facing a severe shortage of cash in the regular budget, and unless more Governments pay their annual dues, “our work and our reforms are at risk,” the UN chief António Guterres has warned Member States.

Each year on 24 October, the UN celebrates its anniversary.  The Day marks the entry into force of the UN Charter and the founding of the Organization.  The Charter was signed on 26 June 1945 in San Francisco at the conclusion of the United Nations Conference on International Organization and the Organization will celebrate its 75th anniversary on 24 October 2020.  Did you know that United Nations Day has been celebrated since 1948?
