Note 2 — ACT III
Edwin Björkman translation
The Folkungs were the descendants of the puissant Earl Birger of Håtuna, who, as an uncrowned king, ruled Sweden in very much the same spirit as King Gustavus himself. The Folkung dynasty reigned from 1250 to 1389—and spent much of that time in fighting among themselves. King Waldemar II gained the name of "Conqueror" by adding Esthonia and other Baltic districts to Denmark.
