Under the global theme Building Our Future Together, the United Nations marked its 80th anniversary, a moment to celebrate eight decades of peace, human rights, and international cooperation, while renewing the collective commitment to a shared and sustainable future.Eighty years on, the United Nations remains a living legacy of multilateralism. Its story is one of endurance and purpose, shaped by generations who believed that dialogue and cooperation must prevail over conflict and isolation. The anniversary serves not only as a tribute to that legacy but also as a call to strengthen it — to make the UN more inclusive, more effective, and more responsive to the needs of the next generation.Senior UN leaders reflected on this milestone and the vision it represents. Secretary-General António Guterres reminded the world, ““We are all privileged to be part of one of the most ambitious and profound undertakings in human history. The decision, despite our differences, to solve problems together, to work sincerely, creatively and humbly toward a better future for all.”President of the General Assembly Annalena Baerbock observed that “we often forget in the trenches of bureaucracy, politics, and diplomacy, how much this institution matters to ordinary people.”UN Deputy Secretary-General Amina Mohammed spoke of unity and renewal, noting that “in this 80th year of the United Nations, it is time to make that choice again and to move forward better together as one human family, as one institution serving humanity.”Under-Secretary-General for Global Communications Melissa Fleming reflected that “we have a United Nations that has an amazing and rich history that we can all be proud of. But that we also have at 80, a United Nations that is renewed, and together, we can be part of its living legacy.”In India, the day was marked with the unveiling of a commemorative UN Day 2025 postage stamp by External Affairs Minister S. Jaishankar at the Ministry of External Affairs. Later in the evening, UN House in New Delhi hosted a reception that brought together diplomats, government officials, and cultural performers to celebrate both United Nations Day and the organisation’s 80th anniversary, an occasion that reflected the spirit of unity and shared purpose.Around the world, the United Nations is marking this milestone with the global photo exhibition Shared Lives, Shared Future, organised by the UN Department of Global Communications in collaboration with the Governments of Italy, Slovenia, and Switzerland. The exhibition features over 200 human stories from all 193 Member States and celebrates the diversity and resilience that define our shared global journey. It remains on view at UN Headquarters in New York until January 2026 and can also be explored online at un.org/en/exhibits/exhibit/un80.
