If the Kalmar Union or Sweden got in a war with the Novgorod Republic, and won by a huge margin, could they conquer the Novgorod Republic? It doesn't matter when really (preferably after 1300 or even 1400), could the Swedish conquer and retain all of the lands of the Novgorod Republic? Say they brutally defeat them in a war, and occupy most of the state. Could that lead to Sweden annexing Novgorod? Or would they be more likely to just annex Karelia and Kola and leave the rest alone?
