[1] His short reign was characterised by disputes with the Archbishopric of Bremen over church policies, and a historically debated delimitation of the Swedish-Danish border.
[5] The German ecclesiastical chronicler Adam of Bremen, in his Gesta Hammaburgensis Ecclesiae Pontificum (Deeds of Bishops of the Hamburg Church), says that Anund Jacob died in or shortly after 1049 and was succeeded by Emund; there is nothing to suggest that the succession was irregular.
He also gives Emund the cognomen pessimus (worst), which is later reflected by the short chronicle of the Westrogothic law (c. 1240) which likewise knows the king as Slemme, the bad.
Originally a protégé of the Norwegian-based missionary Sigfrid, Osmundus had been raised at a school in Bremen but failed to be ordained bishop by the Pope.
Eventually he was ordained by the Polish archbishop of Gniezno and proceeded to Sweden where he won the confidence of King Emund.
The delegation was highly offended when encountering Osmundus who sported the habits of an archbishop and "seduced the still recently converted wild peoples through incorrect education in our faith".
[9] Some time after the schism, King Emund dispatched his son Anund with an army "in order to expand the realm".
Modern scholars have assumed that the term alludes to Kvenland which was probably situated to the east of the Gulf of Bothnia in present-day Finland (Kven could have been mixed up with the Nordic word kvinna, woman).
[11] Allegedly, the calamities caused the Swedes to turn to the Archbishop of Bremen and ask to receive Adalvard back as Bremen-appointed bishop.
He may have continued his brother Anund Jacob's support for the Danish king Sweyn Estridsen against Harald Hardrada of Norway.
[15] A memorandum about an early delimitation of the Swedish-Danish border has been preserved in a large number of medieval Swedish manuscripts.
Now is enumerated Ragnvalde of Tiundaland, Botvid of Hälsingland, Bote of Fjärdhundraland, Grimalde of Östergötland, Tole and Tote and Tokke of Jutland, Gunkil of Sjaelland, Dan of Scania, Grimulf of Grimeton in Halland.
[22] Astrid was the daughter of Norwegian nobleman Nial Finnsson (d. 1011), son of Gunhild Halvdansdotter of the Skjalga family in Hålogaland, Norway.
[24] Adam of Bremen relates in his work that Emund was succeeded by his "nephew or stepson", in fact probably son-in law, Stenkil.
[25] The Hervarar saga (13th century) says that Emund was king only a short time: Eymundr hét annarr sonr Óláfs sænska, er konungdóm tók eptir bróður sinn.
