In modern Swedish, Folkung has two meanings, which appear to be opposites:
Until the 17th century, Folkunge was used only with the second meaning. However, many of these political opponents were also said to have been descendants of Jarl Folke the Fat (from the House of Bjelbo), who lived before the family became royal. Hence, in the 17th century, the whole family, then already extinct and without any established name, became known as the House of Folkung (Folkungaätten in Swedish).
Later research, though, showed that the political Folkungs were not just descendants of Jarl Folke—instead, they belonged to different Swedish noble families, united by the ambition to fight against a central ruler of Sweden. According to one theory, Folkungs wanted to keep the old "freedom" of the petty kingdoms, including the election of kings, and to retain local power in their own control. [2] Many Folkungs came from the ancient provinces of Svealand, opposing the ruling families of the time that were mostly from Götaland. The first Folkung uprising in 1229 was successful, elevating Canute II onto the throne. Later developments were less promising, and the centralized system eventually suppressed their resistance.
Swedish pre-history ends around 800 AD, when the Viking Age begins and written sources are available. The Viking Age lasted until the mid-11th century. Scandinavia was formally Christianized by 1100 AD. The period 1050 to 1350—when the Black Death struck Europe—is considered the Older Middle Ages. The Kalmar Union between the Scandinavian countries was established in 1397 and lasted until King Gustav Vasa ended it upon seizing power. The period 1350 to 1523 – when king Gustav Vasa, who led the unification of Sweden, was crowned – is considered the Younger Middle Ages.

Eric "XI" the Lisp and Lame Swedish: Erik Eriksson or Erik läspe och halte; Old Norse: Eiríkr Eiríksson was king of Sweden in 1222–29 and 1234–50. Being the last ruler of the House of Eric, he stood in the shadow of a succession of powerful Jarls, especially his brother-in-law Birger Jarl, whose descendants ruled as kings after his death.
Eric "X" was the King of Sweden between 1208 and 1216. Also known as Eric the Survivor, he was, at his accession to the throne, the only remaining son of King Canute I of Sweden and his queen. The name of his mother is not known, but may have been Cecilia.
