Question: Information: - The Bagli Party or Bagler (Old Norse: "Baglarr", Norwegian Bokmal: "Bagler", Norwegian Nynorsk: "Baglar") was a faction or party during the Norwegian Civil Wars. The Bagler faction was made up principally of the Norwegian aristocracy, clergy and merchants. It was formed in Skane, then part of Denmark, in 1196 principally by Bishop Nicholas Arnesson of Oslo and Archbishop Erik Ivarsson (ca. 11301213) of Nidaros around the pretender Inge Magnusson (nicknamed the Baglar-King) to depose King Sverre Sigurdsson. It contested with the Birkebeiners, essentially a faction of peasants, led by the pretender King Sverre, for control in a Norwegian civil war during the late 12th century. Sverris saga provided Sverre a royal lineage as putative bastard son of the late king Sigurd II of Norway, which in the Norway of the time provided him a claim to the throne. Historians generally agree with the consensus of his time that he was a pretender/ impostor. - Magnus IV Sigurdsson ( ca . 1115 -- 12 November 1139 ) , also known as Magnus the Blind , was King of Norway from 1130 to 1135 and again from 1137 to 1139 . His period as king marked the beginning of the civil war era in Norway , which lasted until 1240 . - The Norwegian Civil War Era (Norwegian: "borgerkrigstiden") is a term used for the period in the history of Norway between 1130-1240. During this time a series of civil wars were fought between rival kings and pretenders to the throne. The reasons for the wars is one of the most debated topics in Norwegian medieval history. The goal of the warring parties was always to put their man on the throne, starting with the death of King Sigurd the Crusader in 1130, a supposedly adored monarch. In the first decades of the civil wars, alliances shifted and centered on the person of a king or pretender, but eventually, towards the end of the 12th century, two rival parties emerged, known as the Birkebeiner and the Bagler. After these two parties were reconciled in 1217, a more ordered system of government centered on the king was gradually able to bring an end to the frequent risings. The failed rising of duke Skule Bardsson in 1240 was the final event of the civil war era. - Skule Bardsson or Duke Skule (Old Norse: Skuli Bararson) ( 24 May 1240) was a Norwegian nobleman and claimant to the royal throne against his son-in-law, King Haakon Haakonsson. Henrik Ibsen's play "Kongs-Emnerne" (1863) is about the dispute between Duke Skule and King Haakon. - The history of Norway has been influenced to an extraordinary degree by the terrain and the climate of the region. About 10,000 BC, following the retreat of the great inland ice sheets, the earliest inhabitants migrated north into the territory which is now Norway. They traveled steadily northwards along the coastal areas, warmed by the Gulf Stream, where life was more bearable. In order to survive they fished and hunted reindeer (and other prey). Between 5,000 BC and 4,000 BC the earliest agricultural settlements appeared around the Oslofjord. Gradually, between 1500 BC and 500 BC, these agricultural settlements spread into the southern areas of Norway - whilst the inhabitants of the northern regions continued to hunt and fish. - The Birkebein Party or Birkebeinar (Old Norse: "Birkibeinar"; Norwegian: "Birkebeinarane" (nynorsk) or "Birkebeinerne" (bokmal)) was the name for a rebellious party in Norway, formed in 1174 around the pretender to the Norwegian throne, Eystein Meyla. The name has its origins in propaganda from the established party that the rebels were so poor that they made their shoes of birch bark. Although originally a pejorative, the opposition adopted the "Birkebeiner" name for themselves, and continued using it after they came to power in 1184. What is the relationship between 'magnus iv of norway' and 'sigurd the crusader'?
