The term Dominion was dropped by all countries that used it, after the British Empire ceased to exist. Dominions were design to exist as nations within the Empire. No Empire means no Dominions.
Very interesting, I didn't even realize that aspect of it. Magar the british empire fizzled out during the ww2, so how do you 'splain the name change 10 years AFTER Pakistan was born?
I honestly didn't even realize that aspect when I asked the question about changing the name back to dominion.
