For the Jacobites, the war was just about over by Christmas Eve, 1715. They had lost the battles of Preston and Sheriffmuir, and their army, which at one time rivalled the government forces, had dissipated. The war had been winnable, but their commander, the Earl of Mar, was incompetent.

Overall the Stuarts were perhaps the worst ruling family in all British history. The Hannoverians may have been ill tempered Germans, but they were Protestants willing to let Parliament mostly run things. The English were never going to let a bunch of Frenchified Scots take over.
Dude didn't want a German to rule Scotland (or any other nationality either, I know what Jacobite means). But still, a guy from Hanover?
