In 1947, October 24 was declared United Nations Day, recalling that the United Nations Charter was ratified on that day in 1945. The Charter had been signed on June 26, 1945 in San Francisco, at the end of the United Nations Conference on International Organization.
The Charter of the United Nations is an international treaty that serves as the foundation for the United Nations and that prevails over all other international treaties. In this regard, the UN states: “due to its unique international character, and the powers of its founding Charter, the United Nations can make decisions on the wide variety of problems humanity faces in the 21st century. As such, the Charter of the United Nations, considered an international treaty, grants it these powers”.
In addition, the body states on its official site that the Charter is an instrument of international law and “is binding on the Member States of the UN. The Charter of the United Nations includes the principles of international relations, from the sovereign equality of States to the prohibition of the use of force in international relations. Since the founding of the UN in 1945, the mission and work of the Organization have been guided by the purposes and principles contained in its founding Charter”.
For United Nations Day 2021, Antonio Gutérres, Secretary General of the UN, states in his message that “We have to unite to face the great challenges and advance in the achievement of the Sustainable Development Goals. Ensuring that all people, everywhere, have access to COVID-19 vaccines as soon as possible. Guaranteeing and defending the rights and dignity of all people, especially the poorest and most disadvantaged, girls and women, and children and young people”.
