In the United Nations system, how many territories were placed under the International Trusteeship System after the Second World War?

Introduction / Context:
After the Second World War, the United Nations created the International Trusteeship System to supervise certain territories that had not yet achieved self government or independence. These territories were placed under trusteeship to be administered by states or the UN until they were ready for self rule. This question tests the specific number of such territories.

Given Data / Assumptions:

• The subject is the International Trusteeship System of the UN.
• The options for the number of territories are 11, 12, 13 and 14.
• We assume the historically accepted figure of territories placed under trusteeship.
• The question refers to total territories, not administering authorities.

Concept / Approach:
The International Trusteeship System covered 11 territories. They were mainly former League of Nations mandates and some territories taken from defeated states. The system aimed at progressive development towards self government and eventual independence, and almost all trusteeship agreements have now been terminated as territories became independent states.

Step-by-Step Solution:
Step 1: Recall that the Trusteeship Council was created to supervise a limited number of trust territories.Step 2: From standard UN facts, remember the figure of 11 trust territories placed under the system.Step 3: Compare the options 11, 12, 13 and 14, and identify 11 as the familiar number.Step 4: Recognise that this figure appears repeatedly in UN related exam notes.Step 5: Conclude that 11 is the correct number of territories placed under the International Trusteeship System.

Verification / Alternative check:
A candidate can verify this by recalling that the Trusteeship Council suspended operations when the last trust territory, Palau, became independent in 1994. Standard references mention that a total of 11 territories were under trusteeship, which helps confirm the answer when cross checked with exam preparation materials.

Why Other Options Are Wrong:
12, 13, 14: None of these figures match the historical record. They are included only as distractors to test whether the candidate has memorised the precise number 11.

Common Pitfalls:
Candidates may guess one of the higher numbers because they assume the colonial map was very large. Others may confuse the number of territories with the number of administering states. It is important to distinguish that the question is about “territories placed under trusteeship”, a fixed and well documented total of 11.

Final Answer:
The number of territories placed under the International Trusteeship System was 11.
