Over what time period did the dynasty of which Eric Christoffersen of Denmark was a member provide the Kings of Denmark?
House of Estridsen The House of Estridsen, sometimes called the Estridsen or Estrith Dynasty, was the dynasty that provided the Kings of Denmark from 1047 to 1412. The dynasty is named after its ancestor Estrid Svendsdatter. The dynasty is sometimes called the "Ulfinger", after Estrid's husband, Ulf the Earl.
Inge the Elder Inge the Elder (Swedish: "Inge Stenkilsson"; Old Norse: "Ingi Steinkelsson") (died c. 1105-1110) was a King of Sweden. In English literature he has also been called "Ingold". While the sources do not allow us to paint a full picture of his term of kingship, he is known to have led a turbulent but at length successful reign of more than two decades. He stands out as a devoted Christian who founded the first abbey in Sweden and acted harshly against pagan practices. The kingdom was still an unstable realm based on alliances of noblemen, and Inge's main power base was in Västergötland and Östergötland; one of the earliest chronicles that mention his reign knows him as "rex gautorum", King of the Geats.
