The Battle of Brávellir or the Battle of Bråvalla was a legendary battle, said to have taken place c.770, that is described in the sagas as taking place on the Brávellir between Sigurd Hring, king of Sweden and the Geats of Västergötland, and his uncle Harald Wartooth, king of Denmark and the Geats of Östergötland. Sources The battle is recounted in several sources such as the Norse sagas Hervarar saga ok Heiðreks, Bósa saga ok Herrauðs and Sǫgubrot af nokkrum fornkonungum, but it is most extensively described in the nationalistic Danish history Gesta Danorum by Saxo Grammaticus. Cause Harald had inherited Sweden from his maternal grandfather Ivar Vidfamne, but ruled Denmark and East Götaland, whereas his subordinate king, Sigurd Hring, was the ruler of Sweden and West Götaland. According to legend, Harald realised that he was now old and might die of old age and therefore not go to Valhalla. He consequently asked Sigurd if he would let him leave this life gloriously in a great battle. Odin is also implicated. Preparation According to Saxo Grammaticus, both hosts prepared for seven years, and mustered armies of 200,000 men. Harald was joined by the legendary heroes Ubbe of Friesland, Uvle Brede, Are the One-eyed, Dag the Fat, Duk the Slav, Hroi Whitebeard and Hothbrodd the Indomitable as well as 300 shieldmaidens led by Hed, Visna of the Slavs and Hedborg. Sigurd recruited the legendary heroes Starkad, Egil the Bald, Grette the Evil (a Norwegian), Blig Bignose, Einar the Fatbellied and Erling Snake. Famous Swedes were Arwakki, Keklu-Karl, Krok the peasant, Gummi and Gudfast from Gislamark. They were joined by scores of Norwegians, Slavs, Finns, Estonians, Curonians, Bjarmians, Livonians, Saxons, Angles, Frisians, Irish, Rus', and others, all picking a side. Whole forests were chopped down in order to build 3000 longships to transport the Swedes. Harald's Danes built so many ships that they were able to walk on them across Øresund. Location The Hervarar saga ok Heiðreks speaks of "Brávelli í eystra Gautlandi" (Bråvalla in East Götaland) and in Sǫgubrot af nokkrum fornkonungum the battle is said to have taken place south of Kolmården, which separated Svealand (Sweden proper) from East Götaland and is where Bråviken is located: "Kolmerkr, er skilr Svíþjóð ok Eystra-Gautland ... sem heitir Brávík". Saxo ends his account by saying "thus ended the battle of Bråvik". Most historians have held the battle to have taken place near Bråviken,
