How the Future of India and USA, was determined by the inability of the Austrian Kings Joseph I and Charles VI, to produce male heirs..
When Joseph 1, died of smallpox in 1711, he had two daughters but no son. As a result, his brother Charles VI, succeeded him on the throne
Given that it was 1700s and the presence of a Son was considered paramount for succession, and the Salic law, in effect at that time barred women from inheritance, Charles VI was the last male heir to the throne, unless Charles VI had a son.
Which he didn't.
But he had 2 daughters, Maria Theresa & Maria Anna. Realizing that his kingdom would be divided on his death, he decided to change the law, and allowed his daughters to inherit the kingdom
Which was pretty sad for thhe daughters of his elder brother, Joseph, who he disinherited
Every other European power was smacking their lips in anticipation, of devouring the wonderful Austro Hungarian empire as a sweet desert, as it's division was imminent.
Things came to head in 1740, when Charles VI died and Maria Theresa became the Empress of Austria.
Half the Europen powers, Like France, Prussia and Spain, sided with the daughters of Joseph, because they wanted to takeover Austria
Britain, Dutch and Russia, sided with Maria Theresa.
This resulted in an 8 year war called the war of Austrian Succession, in which 3,00,000 died
