John I of Sweden

Johan Sverkersson, or John I (c. 1201–1222), was the son of King Sverker II and Ingegerd Birgersdotter. While still an infant in 1202, his father gave him his grandfather's title. After Erik Knutsson died in 1216, the Swedish aristocracy made the teenage Johan king against the Pope's wishes.

Crowned in 1219, he confirmed and enlarged his father's privileges for the bishops. A Swedish expedition against the Estonians ended in disaster, and he died unmarried and childless of illness on Visingsö on 10 March 1222.
