United Nations Organization (UNO)
Origin
The United Nations Organization (UNO) was established to maintain international
peace and security and to prevent future wars after the devastation caused by the
Second World War.
1. Background: Failure of the League of Nations
Before the UNO, there was the League of Nations, formed after World War I in 1919.
Why the League failed:
• It had no military power to enforce decisions
• Major powers like the USA never joined
• Could not stop aggression by Nazi Germany, Italy, and Japan
• Failed to prevent World War II (1939–1945)
The failure of the League made it clear that a stronger international organization was
needed.
2. Impact of the Second World War
World War II caused:
• Massive loss of life (over 60 million deaths)
• Destruction of cities, economies, and infrastructure
• Rise of nuclear weapons (Hiroshima & Nagasaki)
This convinced world leaders that global cooperation was essential to:
• Prevent future wars
• Promote peace, human rights, and development
3. Steps Leading to the Formation of the UNO
The UNO did not emerge suddenly. It was the result of several international conferences
and declarations:
(a) Atlantic Charter (1941)
Issued by Franklin D. Roosevelt (USA) and Winston Churchill (UK)
Proposed principles like:
• No territorial expansion
• Self-determination of nations
• Collective security
,Laid the ideological foundation of the UNO
(b) Declaration by United Nations (1942)
26 Allied nations signed this declaration
The term “United Nations” was used for the first time
Members pledged to fight against Axis Powers and support peace
(c) Moscow Declaration (1943)
Major powers (USA, UK, USSR, China) agreed on the need for a new international
organization
Official acknowledgment that a post-war peace body was necessary
(d) Dumbarton Oaks Conference (1944)
Held in Washington, D.C.
Structure of the UNO was proposed:
• General Assembly
• Security Council
• International Court of Justice
Voting powers and functions were discussed
(e) Yalta Conference (1945)
Leaders: Roosevelt, Churchill, and Stalin
Finalized:
• Veto power of permanent members of the Security Council
• Date and process for a founding conference
4. San Francisco Conference (1945)
Officially called the United Nations Conference on International Organization
Attended by 50 countries
Drafted and signed the UN Charter
The Charter came into force on 24 October 1945
This day is celebrated as United Nations Day
5. Establishment of the UNO
UNO officially came into existence on 24 October 1945
, Headquarters: New York City, USA
Original members: 51 countries
Conclusion
The United Nations Organization originated as a result of the failure of the League of
Nations, the destruction of World War II, and the collective desire of nations to prevent
future conflicts. Through a series of conferences and declarations, the UNO was finally
established in 1945 as a permanent global institution for peace and cooperation.
Objectives
The objectives of the United Nations are clearly stated in Article 1 of the UN Charter.
These objectives aim to promote peace, cooperation, development, and human welfare
across the world.
1. Maintenance of International Peace and Security
The primary objective of the UNO is to:
• Prevent wars and armed conflicts
• Settle international disputes by peaceful means such as negotiation, mediation,
arbitration, and judicial settlement
• Take collective action against aggression or threats to peace
The Security Council plays the key role in fulfilling this objective by:
• Imposing sanctions
• Authorizing peacekeeping operations
• Taking military action when necessary
2. Development of Friendly Relations Among Nations
UNO aims to:
• Promote mutual respect and understanding among countries
• Uphold the principle of sovereign equality of all states
• Encourage self-determination of peoples, helping colonies gain independence
This objective has helped in the decolonization of Asia, Africa, and Latin America.
3. Achievement of International Cooperation
UNO promotes cooperation to solve global problems of:
• Economic nature (poverty, unemployment, trade)
• Social issues (health, education, population)
• Cultural matters (heritage, language, arts)
