Englund thinks that the period of Sweden as a superpower was the common "property" of Sweden and Finland, because the rise as a superpower would have been impossible for a poor nation without the resources of the eastern part of the realm.
Englund anser att Sveriges tid som supermakt var Sveriges och Finlands gemensamma "egendom", eftersom uppkomsten som supermakt skulle ha varit omöjlig för en fattig nation utan resurser i den östra delen av riket.
