Understanding the UN

What the UN is, what it does, and why it matters.

“The UN was not created to take mankind to heaven, but to save humanity from hell.”

Dag Hammarskjöld,
Secretary-General 1953-1961

For many people outside the system – and even some within – the United Nations can be difficult to fully grasp. It is often seen as a single organisation, but in reality, the UN comprises many different parts: specialized agencies, funds and programmes, each with its own mandate, leadership, structure, and budget.

Most of the attention usually goes to what happens at UN Headquarters, especially in the political arena. But beyond the spotlight, the UN plays a vital role in supporting countries through development and humanitarian work. This work is widely appreciated, yet often not well understood. The details – how the UN operates in-country, how decisions are made, how programmes are planned and funded – can seem complex and unclear. This can be confusing even for diplomats, government officials, aid workers, and journalists.

Over the years, efforts have been made to make the UN system more accessible to partners and newcomers alike. Two earlier handbooks laid the groundwork for this microsite: one on the General Assembly and another on the Economic and Social Council—two key organs shaping global policy and development priorities. Together, they offer clear entry points into the UN’s institutional landscape.
