Erengisle Sunesson of Hultboda, jarl of Orkney (died 26 December 1392) was an important Swedish magnate in the 14th century. In his later life, he was known as Jarl Erengisle in Sweden. He was knight, high councillor, and titular (Norwegian) Jarl. Family He was born in a noble family later called Bååt (Old Swedish for boat) originally from Småland, as son of Sune Jonsson, the lawspeaker of Tiohärad, and his first wife Cathrine Henriksdatter Glysing. In 1320, Erengisle's father Sune and uncle Peter obtained the effectively hereditary position of chatelain of Viipuri castle in easternmost coast of Finland by purchasing it from the governor. It was set there by the deposed king Birger of Sweden. Peter and Sune recognized the new king, Magnus IV of Sweden, and received important privileges, which effectively turned their holding of Viipuri as an independent feudal fief, the start of a veritable margraviate (see fief of Viipuri). Life Erengisle possessed immense wealth in several provinces of Sweden. In Viipuri province, his patrimony included Kymenkartano manor, on which spot the later town of Kotka became erected. His chief seat was the medieval castle of Hultaboda (now Hultaby) in Näsby outside of Vetlanda. Also Flishult manor in the same district belonged to him. He was usually a supporter of his king, Magnus VII of Norway and Sweden, although in some instances he was in alliance with king's rivals. The king's Norwegian tasks for him led to his marriage with an unnamed daughter (possibly Agnes) of Maol Íosa, the Jarl of Orkney (including Caithness), and Earl of Strathearn. Because Maol Íosa did not have sons, families of his daughters divided or competed over his inheritance. Erengisle became the Orkney Jarl, although there is little evidence that he ever treated it as anything other than a high title, bringing him prestige over the then titleless Swedish nobility; he doesn't even seem to have ever visited his jarldom. In 1357 Erengisle was among magnates who proclaimed Eric, the eldest son of king Magnus, as king in place of the father. He then led negotiations which resulted in reconciliation between father and son, with them splitting the kingship. The marriage of Haakon VI of Norway to the daughter of Valdemar IV of Denmark, and Eric's sudden death (from The Plague), drastically changed the political dynamic of Scandinavia, leading Erengisle to be ejected from the Jarldom in 1359. The Jarldom lay vacant
