Re: Hindustan - Pakistan - An Independent States
Not two domains, but two dominions. Under English Common Law, the term Dominion referred to all lands under the sovereignty of the crown.
Pakistan became independent as the Dominion of Pakistan, because all land in Pakistan was under the sovereignty of the Pakistani Crown.
Similarly, at India’s independence, all lands in India were under the sovereignty of the Indian Crown, hence it was the Dominion of India.
Britain used the term “Dominion” for the legal name of its newly independent former colonies starting from 1867, when Canada was founded. Since the USA had fought for its independence from the British Monarchy less than 100 years earlier, Britain felt that it would be a needless provocation to create a new “Kingdom” in North America next to the USA - instead, the word “Dominion” was used.
This created a precedent for all countries becoming independent from Britain until after the British Commonwealth was renamed to Commonwealth of Nations.
If not for the fear of proving the USA in 1867, Pakistan and India would have become independent under the names of “The Kingdom of Pakistan” and “The Kingdom of India”
