Who was the last ruler of the Swedish Empire?
Swedish Empire
After the death of Gustavus Adolphus in 1632, the empire was controlled for lengthy periods by part of the high nobility, most prominently the Oxenstierna family, acting as tutors for minor regents. The interests of the high nobility contrasted with the uniformity policy (i.e., upholding the traditional equality in status of the Swedish estates favoured by the kings and peasantry). In territories acquired during the periods of de facto noble rule, serfdom was not abolished, and there was also a trend to set up respective estates in Sweden proper. The Great Reduction of 1680 put an end to these efforts of the nobility and required them to return estates once gained from the crown to the king. Serfdom, however, remained in force in the dominions acquired in the Holy Roman Empire and in Swedish Estonia, where a consequent application of the uniformity policy was hindered by the treaties by which they were gained.
