After a bit of consideration, I think I'll lay claim on Canada. I'll be working under the assumption that in the 1930's, spurred on by unrest and economic decline, a brief but fierce Second English Civil war occurred, resulting in a British Republic dominated by socialist and left-wing interests, resulting in the exile of the Royal family along with large flocks of conservatives, government officials, significant elements of the Royal Navy, and others. Hopefully the result ends up interesting. With the instability of its neighbor and different, more active King in the form of a determined Edward VIII, Canada should be on a much different trajectory than OTL.
