Eric XI of Sweden

Eric XI (Erik Eriksson, 1216–1250), surnamed the Lisp and Lame, was the posthumous son of Eric X and Rikissa of Denmark. He became king at six in 1222, was overthrown by Knut Långe at Olustra in 1229 and fled to Denmark, returning after Knut's death in 1234.

He ruled in the shadow of his jarls Ulf Fase and brother-in-law Birger Jarl. In 1247 a Folkung rising was crushed at Sparrsätra. Eric died on 2 February 1250, the last of the House of Erik; Birger Jarl's son Valdemar became king.
