I had an idea for a timeline but I didn't know if it could work or if anything like it has been done. This timeline starts at the English Civil War. Before Charles I is captured, he and a large number of Royalists flee to the colonies and set up a new government. This also involves the survival of the Commonwealth of England. Charles I and about 2 or 3 generations of succesors continue to claim the title of King of England, Scottland and Ireland, but have no actual control. Charles I loses any political ties in England, so he doesn't have powerbase to return to. Eventually they establish the English Colonies in North America as an Empire.
