The origin of the Commonwealth of Nations can be traced to

Step 1: Analyze the question The question asks where the Commonwealth of Nations originated, meaning what historical basis led to its formation.

Step 2: Explain the concept The Commonwealth of Nations is an association of independent countries. Most of them were once part of the British Empire. It grew out of the British Empire: in the early 20th century, self-governing dominions such as Canada, Australia, New Zealand and South Africa gained more autonomy. The Balfour Declaration of 1926 and the Statute of Westminster of 1931 recognised them as equal members of a "British Commonwealth of Nations." After World War II, former colonies like India, Ghana and Nigeria joined as they became independent, and the word "British" was dropped.

Step 3: Evaluate the options

• A. Colonial ties: Correct. The membership is built on the shared history of British colonial rule, along with common language, law and institutions.
• B. World economic order: Incorrect. The Commonwealth did not start as an economic system. That idea is linked to bodies like the IMF and World Bank.
• C. Equality of states: This is a principle the Commonwealth adopted (the 1926 declaration), but it describes how members relate to one another. It is not the origin.
• D. Sovereignty of states: This is a general principle of international law and does not explain how the Commonwealth began.

Step 4: Answer The origin of the Commonwealth of Nations can be traced to colonial ties, which is option A.

Tip: For "origin" questions on the Commonwealth, remember: Commonwealth = Britain + her former colonies. Principles such as equality are what the group practises, while colonial history is where it came from.
