So simple scenario. Sweden somehow keeps Finland in 1809. Whether the punishment was lighter (for whatever reason) or Sweden caved and agreed to the continental system (unlikely), they don't lose Finland to Russia.
My main question is this: When does Finland get independence than? Does Finland get independence at all? Finland had been an integral part of Sweden for over 500 years when it was lost to Russia, so it could be theoretically possible that Sweden and Finland exist in harmony. At the same time though, the rise of nationalism throughout Europe would unlikely pass by Finland, so they agitate for some sort of Finnish state, whether a new kingdom in union with Sweden or simply sharing a royal family, or separating completely and becoming a republic or a monarchy under a different royal family (probably German).
Follow-up question: What would the border be between Sweden and Finland (possibly also between Finland and Norway, depending on Norway's fate in this TL)? Would it still follow the Torne River? Or would a new, more complex border be drawn, featuring more Swedish speakers staying in Sweden rather than Finland and vice versa (maybe even including Sami with the Finns)?
