Which of the following World Organization preceded the establishment of UNO?

Step 1: Analyze the question The question asks which world organization came before the United Nations Organization (UNO), which was established in 1945.

Step 2: Explain the concept After World War I, world leaders wanted to prevent another global war. The Treaty of Versailles (1919) created the League of Nations in 1920, based in Geneva, Switzerland. It aimed to maintain peace through collective security and international cooperation. However, it was weakened by:

• The absence of the USA, which never joined
• Lack of its own military force
• Failure to stop aggression by Japan (Manchuria, 1931), Italy (Ethiopia, 1935), and Germany

It collapsed with the outbreak of World War II in 1939, and the UNO replaced it in 1945.

Step 3: Check each option

• A. International Court of Justice: This is the principal judicial organ of the UN, created in 1945. It is part of UNO, not a predecessor.
• B. International Labour Organisation (ILO): It was founded in 1919, so it technically existed before UNO. However, it was created alongside the League of Nations and later became a UN specialized agency. It is not the direct predecessor of the UN.
• C. League of Nations: This is the direct predecessor of UNO. ✔
• D. OPEC: Founded in 1960, long after UNO.
• E. Security Council: This is an organ of the UN, created in 1945.

Step 4: Answer The League of Nations was the world organization that UNO directly succeeded, so the answer is C.

Tip: Remember the sequence "League first, UN after": League of Nations (1920) → UNO (1945). When a question asks for the "predecessor" of the UN, think League of Nations. Be careful with ILO: it is older than the UN, but it is not the organization the UN replaced.
