The rule
The United Nations (UN) has six main organs: the General Assembly, Security Council, Economic and Social Council, International Court of Justice, Secretariat, and Trusteeship Council.
Let's understand it simply
Imagine the UN as a big school. To run the school well, there are different groups: one for making rules, one for solving fights, one for keeping records, one for helping with money and social problems, one for judging, and one for looking after special students. The UN works the same way. Each organ is like a team with a special job.
How it works
General Assembly: All countries meet, discuss, and make decisions together.
Security Council: Handles peace and security; can send peacekeepers or ask countries to stop fighting.
Economic and Social Council (ECOSOC): Works on health, education, and development problems.
International Court of Justice (ICJ): Judges disputes between countries, like a court.
Secretariat: The office staff; runs daily work, led by the Secretary-General.
Trusteeship Council: Used to help countries become independent; now mostly inactive.
The Six Main Organs of the UN
General Assembly: All countries discuss and decide.
Security Council: Keeps peace and security.
Economic and Social Council: Works on development and health.
International Court of Justice: Judges between countries.
Secretariat: Runs daily work.
Trusteeship Council: Helped countries become independent.
The story behind it
The UN was created in 1945, just after World War II, when many countries wanted to avoid another big war. Leaders met in San Francisco to design an organization that could keep peace and help solve world problems. They decided to give each main job to a different organ, so the UN could work smoothly, like a well-run team.
Where you see it in real life
General Assembly: All countries meet in New York every year to talk about world issues.
Security Council: Sent peacekeepers to Kashmir to keep peace between India and Pakistan.
ECOSOC: Supports health programs like fighting diseases (e.g., polio in India).
ICJ: Settled disputes, like the border case between India and Bangladesh.
Secretariat: Organizes UN events, sends out reports, supports missions during disasters (like after a tsunami).
Trusteeship Council: Helped many African countries become independent in the past.
Why it matters
Each organ does a special job, so the UN can handle many problems at once.
The Security Council helps stop wars and keeps peace.
ECOSOC helps with health, education, and poverty, which affects daily life.
The ICJ gives countries a way to solve arguments without fighting.
Common mistakes
Thinking all organs have equal power: The Security Council has more power for peace and security.
Forgetting the Trusteeship Council: It is now mostly inactive but was important before.
Mixing up the Secretariat with the Secretary-General: The Secretariat is the whole office, not just one person.
Remember it
Think: Great Schools Explain Important Stuff Together — General Assembly, Security Council, ECOSOC, ICJ, Secretariat, Trusteeship Council.
