I recall discussing that an alliance was in the works, not that one currently existed.
Also . . Skane has been Swedish for well over a century even OTL, and Norway was acquired in the Great Northern War. The Orkneys have also been Scottish for centuries I believe.


And I don't even send my King, but only a duke. Nonetheless I could well imagine that Prussia, Austria and Russia discuss their points alone before inviting Bosnia in to sign the treates.
