viewed Napoleon in a more positive way than Gustav IV Adolf had, who had held him in very ill regard. Another point in favour was that a large part of the Swedish Army, anticipating conflict with Russia, were in favour of electing a soldier. Also, Bernadotte was personally popular, owing to the kindness he had shown to the Swedish prisoners in Lübeck and his reputation as the well-liked governor of the Hanseatic Cities from 1807 to 1809; as many Swedish merchants had operated under his auspices. Finally, Bernadotte had no qualms about converting to Lutheranism, recalling the conversion of Henry IV for the benefit of France with whom he felt a kinship with as both hailed from Pau, nor converting his son Oscar (though his wife Désirée never did renounce Catholicism).
