About Us

One place where the world's nations can
gather together, discuss common problems
and find shared solutions.

The United Nations is an international organization founded in 1945. Currently made up of 193 Member States, the UN and its work are guided by the purposes and principles contained in its founding Charter.

The UN has evolved over the years to keep pace with a rapidly changing world.

But one thing has stayed the same: it remains the one place on Earth where all the world’s nations can gather together, discuss common problems, and find shared solutions that benefit all of humanity.

The United Nations is part of the UN system, which, in addition to the UN itself, comprises many programmes, funds and specialized agencies, each of which have their own area of work, leadership and budget.

The UN coordinates its work with these separate UN system entities, all of which cooperate with the Organization to help it achieve its goals.
