The alteration in status was stirred by a sentiment on the part of the prime ministers of the self-governing colonies of the British Empire that a new term was necessary to differentiate them from the non-self-governing colonies. At the 1907 Imperial Conference, it was argued that self-governing colonies that were not styled 'Dominion' (like Canada) or 'commonwealth' (like Australia) should be designated by some such title as 'state of the empire'. After much debate over lexicon, the term 'Dominion' was decided upon.
