In 1177, the defrocked priest Sverre Sigurdsson left the Faroe Islands in the North Atlantic for the shores of Norway with the resolute intention of claiming the throne of Norway 1. According to the Sverris saga 2 , soon after landing in Norway, Sverre took command of a rebel faction, the Birchlegs, whom he subsequently led to numerous victories. Eventually, Sverre became the sole king and went on to "enjoy" 18 long, yet troubled years in power. His rise to royal power was troubled likewise, as the Norwegian throne was already occupied by King Magnus V Erlingsson (1161-1184), who needed to be driven out. 2 Like any usurper with royal ambitions, Sverre faced two main challenges: to gain support for his cause and, in turn, eliminate his enemies. However, Sverre suffered from several handicaps. These are summed up perfectly in the prologue of a late 14 th-century version of the Sverris saga: "But neither goods nor kin supported Sverre and no friends either, as one should know, as he came in the country young and alone and unknown to any" 3. No one in Norway was waiting for him or ready and willing to support his cause. The latter challenge proved particularly troublesome and would remain a stumbling block until his death in 1202. His claim to the throne rested upon a dubious assertion of royal descent, as he declared he was an illegitimate son of the late King Sigurd II Munn (1133-1155). His kinship with that monarch could not be legally proven, nor was there anyone in Norway ready to acknowledge it 4. Furthermore, his intention of asserting his claim by force seemed incredible, for Sverre neither commanded armies nor possessed the resources Staging deaths: King Sverre or a usurper's path to the throne
