Commonwealth – A Voluntary association of 53 independent and equal sovereign states, which were mostly territories of the former British empire
The commonwealth is home to 2.2 billion citizens. Member states have no legal obligation to one another. Instead they are united by language, history, culture and their shared values of democracy, human rights and the rule of law.
Common Wealth, no, but common language, law and democracy, yes.
To remember that there are 53 member states notice that all the people above were wearing the holy rosary beads.
And there are 53 Hail Mary beads on the typical rosary used by most Catholics.
NOTE: The Commonwealth countries are not dominated by the catholic religion: this is used only as a mnemonic or aid to memory.
Or if you use our Mammoth Memory Number System, 53 is lamb. So think of a lamb wearing rosary beads.
