Eystein was son of King
Eystein II Haraldsson. His nickname
Møyla means maiden, girl, cute woman. His father was king of Norway from 1142 to 1157, ruling as co-ruler with his brothers,
Inge Haraldsson and
Sigurd II Munn. Eystein II was killed in 1157 during the power-struggle against his brother, Inge, in an early stage of the
civil war era in Norway. After the death of Eystein II, his supporters first rallied around the young
Haakon II the Broadshouldered, Sigurd Munn's son and Eystein's nephew. Haakon was defeated and killed by Jarl
Erling Skakke at Sekken near the town of
Veøya in
Romsdalen during 1162.

Erik Werenskiold, 1899 The
Birkebeiner were formed in 1174 around Eystein Meyla. The Birkebeiner took the city of
Trondheim and proclaimed Eystein to be king at the Øretinget
Thing by the mouth of the river
Nidelva in during 1176. Eystein Meyla and the party of
Birkebeins subsequently arose in rebellion against Erling Skakke and his young son Magnus Erlingsson who reigned as King
Magnus V of Norway from 1161–1184. In January 1177, the Birkebeiners met a crushing defeat at the
Battle of Re in
Vestfold. Eystein escaped the battle alive, but was killed by a farmer when he tried to ask for
grið (mercy). The battle was the last one mentioned in
Heimskringla by
Snorri Sturluson. Sverre Sigurdsson became the Birkebeiners’ next leader. As King
Sverre I, he would rule as king of Norway from 1184 until his death in 1202. ==Historic overview==
