Un
In short
The United Nations is a global organisation formed in 1945 to keep international peace and help countries work together.
In plain words
It is a large group where almost every country in the world meets to solve problems. They work on stopping wars, protecting human rights, and helping people in need.
A simple example
When a natural disaster hits a country, the UN sends food, water, and medical teams to help the survivors.
Why it matters
It provides a neutral place for nations to talk instead of fighting. It also sets global rules for things like climate change and human rights.
Easy to mix up
People often confuse the UN with the World Bank or the IMF, which focus specifically on money and loans.
