The Norwegian Civil Wars were a period of near continuous unrest that lasted for over a century, from1130 until 1240, and saw over twenty kings, pretenders, and claimants battling for control of the kingdom. Amidst this turmoil the reign of Sverre Sigurdson, who claimed the Norwegian throne in 1177 but only ruled as Sverre I from 1184 until his death in 1202, contains an interesting anecdote in the history of the crossbow.
Sverre’s rule was one marked by near constant conflict. He had originated as a pretender to the throne before eventually achieving legitimacy through warfare. An account of his reign was provided by the Sverris Saga, a poetic account of his life probably written by Karl Jónsson, abbot of the Benedictine monastery of Munkaþverá in Northern Iceland. Jónsson died in 1213, meaning that the saga must have been written nearly contemporary to Sverre’s life. The saga says that Sverre’s initial group of followers consisted mainly of “vagrants, outcasts, and robbers who are primarily interested in plundering farmers.”
