By 1708, two big things had happened that would change Britain forever, the Act of Settlement had been passed in 1701, thus stating that Sophia of Hanover was now the heir to the British throne and her children after her, and the Act of Union in 1707 which united England and Scotland into one kingdom. In early 1708, James Francis Edward Stuart, otherwise known as the old pretender attempted a landing in Scotland, this landing failed, and also led to Queen Anne vetoing the Scottish Militia Bill, one of the last times the monarch has ever stopped a bill becoming law.

Now, I believe later on in 1708, Anne's husband George, Duke of Cumberland died and Anne was quite distraught, the Whig Junto were in power in Parliament and essentially committing treason by forcing their Queen to accept Whig ministers into government, what if the combination of her own ill health and her husband's death pushed Anne over the edge and she ended up dying at the end of 1708?

Now the Act of Settlement is clear, Sophia of Hanover is now Queen Sophia I, but, the Whigs are growing ever more unpopular, and the Tories had never quite been behind the Act of Settlement to begin with. What does Anne's death in 1708 do? Does it spark another war? Does James Stuart attempt another landing, does he gain more support from France, and from Jacobites in Britain who don't want a German on the throne? What would the Duke of Marlborough do as one of the most powerful men in the realm at the time, and also as a suspected Jacobite himself.
