History of United Nations Day

After the tragic world wars of the early 20th century, the need for an international body to prevent future conflicts became evident. Thus, on October 24, 1945, the United Nations Charter officially came into force.

Originally formed by 51 nations, the UN has now grown to 193 member states, representing nearly every corner of the world. In 1947, the UN General Assembly designated October 24 as United Nations Day to celebrate the principles of peace and unity outlined in the Charter.

This year, 2025, marks the 80th anniversary of this milestone — a testament to eight decades of diplomacy, progress, and global cooperation.
