By 1812 Britain was a Constitutional monarchy, in which the power to declare war was vested in the Parliment. For that matter it still is. It WAS a democratic nation in 1812 in the sense that it was a democratic nation in 1914 and in 2005
The last king that believed Britain was a monarchy had the government disagree with him to the point where he lost his head over the issue.

No doubt at all that Great Britain was a democratic nation in 1812. Anyone who argues otherwise needs to hit the books.
Actually it was another king 40 years later, and he just left the country after the government brought William of Orange over to replace him.
The Britain of 1812 had extremely limited voting rights.
