According to the sagas, relations between the three brothers were peaceful as long as the two younger brothers' guardians were alive. But as the younger brothers grew up, tensions arose. In 1155, a meeting between the brothers in
Bergen resulted in fighting breaking out between the men of king Inge and king Sigurd, in which king Sigurd was killed. King Eystein was late in arriving for the meeting, and only approached the city after Sigurd was already dead. An uneasy settlement was reached between Inge and Eystein. The reasons for the fighting in Bergen remain disputed. According to the sagas, Eystein and Sigurd had plotted to strip Inge of his royal title and divide his share of the kingdom between them. Some modern historians doubt this version, seeing it as Inge's excuse for his own aggressive actions. In any event, peace between Inge and Eystein did not hold for long after the events of 1155. In 1157, both sides gathered their forces for a confrontation. Inge's forces outnumbered Eystein's, and when they met, on the west coast near
Moster, Eystein's forces melted away. Eystein was forced to flee, over land to Viken (the
Oslofjord-area). Abandoned by his own men, he was caught, somewhere in the area of present-day
Bohuslän, and killed by his captors. Whether or not king Inge ordered his killing seems to have been a disputed question at the time. Eystein's body was buried in the church of
Foss in
Tunge Hundred. According to Heimskringla, the local population of the area started worshipping Eystein as a saint. ==Aftermath==
