The United Nations was founded in 1945, when its charter was ratified by – among others – China, France, the Soviet Union, the United Kingdom and the United States.

The name “United Nations” was coined United States President Franklin D. Roosevelt during World War II, when representatives of 26 nations pledged their governments to continue fighting together against the Axis powers.

The Axis Powers, also known as the Rome-Berlin-Tokyo Axis, fought against the Allied powers.

This year’s UN Day will be used to highlight concrete actions people can take to achieve the Sustainable Development Goals for 2015-2030.

The UN currently has 193 member states, and is made of smaller organisations each with a different priority such as the UN Security Council.
