Wanting ideas because i was thinking of doing a TL along these lines, namely, what if the American Revolution spreads to Britain and the rest of the Empire? IOTL, British citizens were taxed just as much if not more than Americans and some of Britains largest cities still did not have representation in Parliament and there was a large sect of thinkers and politicians who were sympathetic to the colonists plight aswell as a lot of unrest and rioting (i.e the Gordon Riots).
So what would it take for the revolution to jump the pond? And what happens if it succeeds? Do we end up with a United States of Great Britain and North America? What about the British Empire? And what happens when a French Revolution analogue comes around?
