Of particular concern/interest, I'd like to know what people think of whether in this reality, Ireland is still a member and a monarchy, if the Commonwealth would allow for republics now, if the term dominion ought to be supplanted by Commonwealth and the status of Somalia.
There are republics in the commonwealth such as India and Pakistan. Dominion status should not be supplanted. For example Canada was the first Dominion of the British Empire created in 1867 whose status as a Dominion continued through the creation of the Commonwealth until 1982 when the Constitution was repatriated and it continues as a Commonwealth Realm and independent constitutional monarchy. BTW the crown is not shared. There are seperate crowns for each commonwealth realm created in 1931. For example Queen Elizabeth II is Queen of the United Kingdom, Queen of Canada, Queen of Australia etc.
