Person:Alv Erlingsson Tanberg (1)

Han startet sin løpebane til sjøs i 1276, og ble betraktet som sjøheltpå grunn av sine seire mot hanseatene. "I 1284-85 hadde han, trolig påegen hånd, provosert fram den hanseatiske blokaden gjennom kaperangrep på tyske skip fra Glomma-munningen og herjinger i danske farvann. I 1286 ble han utnevnt til jarl, tydeligvis for å gjøre angrep på Danmark. Han opptok lån fra kong Edvard 1. og vervet med hanstillatelse krigsfolk i engelske havner." Ascheh. Norgeshist, 3/203.I 1287 gjorde Alv Erlingson opprør mot hertug Håkon, overfalt hans borgi Oslo, brente bispesetet, tok kommandanten til fange og lot hamdrepe. Opprøret mislyktes, 260 mann ble drept, og Alv og hans menn ble erklært fredløse. Alv måtte rømme til Sverige, der kong Magnus tok seg avham.I 1290, da kong Erik av Norge og danske kongemordere sloss motdanskene, dukket imidlertid herr Alv opp igjen på herjetokt i Danmark.Han ble fanget ved Helsingborg, lemlestet og drept.En heltevise om ham lyder: "Synden seilede de tyske Mænd, alt både med Miel og Malt, Alven ligger ved Øresund og tager ifra dennem alt."

English notes (these are not a translation of the above but cover some of the same information): Alv Erlingsson was a Norwegian baron and earl. He inherited property in Østfold, and from Isegran at the mouth of the Glomma he ravaged Denmark during the 1284-85 war. In 1286 he conducted a successful mission to England for the Norwegian king, but lost favor the next year when the dowager Queen Ingebjørg died. He carried out an unsuccessful rebellion and escaped to Sweden. When Norway was again at war with Denmark in 1290, he came home and was involved in the war, but was taken prisoner and executed in 1290. He is the subject of the ballad of Minder-Alv (Lessor-Alv).^[1]

Alv Erlingsson (Alv Erlingsson den yngre, died 1290) was a Norwegian nobleman, earl of Sarpsborg and governor of Borgarsyssel.

Alv Erlingsson was born at Tanberg in Norderhov, Buskerud. Alv Erlingsson was the son of Erling Alvsson of Tanberg (ca. 1230–1283) and grandson of Alv Erlingsson of Tanberg (ca. 1190 – ca. 1240). Tanberg (Tornberg) was an old manor which was considered to have been among the oldest farms in Norderhov. His grandmother was Ingeborg Baardsdatter of Rein, sister of Duke Skule Bårdsson. Alv Erlingsson was also a second cousin of King Magnus VI of Norway.

With his father's death in 1283, Alv Erlingsson inherited Sarpsborg and served as governor of Borgarsyssel which today makes up the county of Østfold. Alv Erlingsson had a central role in Norwegian national governance following the death of King Magnus VI in 1280. King Magnus's heir, Eirik Magnusson was a minor and unable to take government control in his own hands. A guardianship board was established which would rule the kingdom on behalf of the king until he was of age. Alv was not included in the formal guardianship government, but had much power as governor of Borgarsyssel.

It is said he was a favorite of Ingeborg of Denmark, Queen of Norway, yet he committed countless acts of piracy throughout his life including making an attack on her son, Duke Håkon later Haakon V of Norway. The first construction of Akershus Fortress was started around the late 1290s by King Haakon V in response to earlier attack on Oslo by Alv Erlingsson.

His actions included seizing and robbing Danish and German vessels. Alv Erlingsson was eventually exiled for his acts. In the spring of 1290 Alv was caught on the coast of Scania by Danish forces. By order of the King of Denmark, Alv was sentenced to death and was executed outside Helsingborg.
