Sweyn II of Denmark

Sweyn II (c. 1019 – 28 April 1076), also known as Sweyn Estridsson (Old Norse: Sveinn Ástríðarson, Danish: Svend Estridsen) and Sweyn Ulfsson, was King of Denmark from 1047 until his death in 1076. He was the son of Ulf Thorgilsson and Estrid Svendsdatter, and the grandson of Sweyn Forkbeard through his mother's line. He was married at least twice, and fathered 20 children or more out of wedlock, including the five future kings Harald Hen, Saint Canute, Oluf Hunger, Eric Evergood, and Niels.

He was courageous in battle, but did not have much success as a military commander. His skeleton reveals that he was a tall, powerfully built man who walked with a limp.
