Here’s an interesting bit of counterfactual speculation from an article in today’s Daily Mail about the imminent royal baby birth in Britain:
In October 2011, British Prime Minister David Cameron announced that the 16 Commonwealth countries where the Queen is head of state had agreed to give female royals the same rights of succession as their brothers.
Under the ancient rules of male primogeniture, first born royal daughters in direct line to the throne were overtaken by younger male siblings.
The scrapped law of male primogeniture only allowed Elizabeth II to become Queen because she did not have any brothers.
Constitutional experts say that in 1509 Margaret Tudor would have taken the throne instead of Henry VIII, and as a result Elizabeth I would never have been Queen.
It would also have meant Queen Victoria would have been succeeded by her daughter, Princess Victoria, the Princess Royal, in 1901, and not King Edward VII.
When she died just a few months later, her son Kaiser Wilhelm II would have ascended the throne – something which could have prevented the First World War.
It is said the Queen of England now would have been the completely unknown Princess Marie Cecile of Prussia.
