Einar Tambarskjelve

Einar Eindridesson Thambarskelfir (c. 980–c. 1050) (Old Norse: Einarr Þambarskelfir, Modern Norwegian: Einar Tambarskjelve) was an influential Norwegian noble and politician during the 11th century. He headed the feudal lords in their opposition to Olaf Haraldsson.

Several references are made to him in Snorri Sturluson's Heimskringla. His cognomen, Thambarskelfir, has two strongly differing explanations. One is that it is derived from tomb, meaning shaking bowstring. Thus, the name suggests a master of the longbow. The other is that it is derived from tambr, meaning 'belly', and that it translates to 'wobbly belly', surely an unflattering reflection of his physical build.

Einarr Thambarskelfir was the son of Eindride, a rich and influential farmer at the Viking Age political center of Melhus. Einar Thambarskelfir was a jarl and chieftain at Husaby, and a powerful warlord with his own army. He descended from the Earls of Lade , one of the dominant families of Norwegian Viking Age politics. He made his debut both as a saga character and in the political arena at the sea Battle of Svolder in 1000, fighting on the losing side of Olaf Tryggvason. From his description of this battle, Snorri presents us with one of the saga's most famous passages:

King Olaf Tryggvason disappeared during the battle, though his corpse was never found after the Battle of Svolder. Einar, however, survived, and spent the next decades maneuvring through shifting political waters. Einar, together with Erling Skjalgsson, supported Lade jarl Sveinn Hákonarson against Olaf Haraldsson at the Battle at Nesjar in 1016. While Sveinn had to flee the country after the battle, and Erling was forced to join an uneasy alliance with the new king, Einar remained unscathed. He returned to Melhus and remained an opponent of the king. Therefore, when Danish influences sought to overthrow Olaf Haraldsson in 1028, he supported them. However, he did not join the peasants' army at the Battle of Stiklestad. This was more due to luck than calculation – when news of Olaf's presence in Trøndelag broke, Einarr was in England, making a political visit to the Anglo-Danish King Cnut the Great. However, this move would later pay off handsomely.
