Jomsvikings

The Jomsvikings were a possibly-legendary company of Viking mercenaries or brigands of the 10th century and 11th century, dedicated to the worship of such deities as Odin and Thor. They were staunchly pagan, but they reputedly would fight for any lord able to pay their substantial fees, and occasionally fought alongside Christian rulers. According to the Norse sagas (particularly the Jómsvíkinga saga, King Olaf Tryggvasson’s Saga, and stories found in the Flatey Book), their stronghold Jomsborg was located on the southern shore of the Baltic Sea, but the exact location is disputed by modern historians and archeologists. Most scholars locate it on the hill Silberberg north of the town of Wollin on Wollin island. Jomsborg is thought to be identical with "Jumne", "Julin" and "Vineta" mentioned in medieval Danish and German records.

The legend of the Jomsvikings appears in some of the Icelandic sagas from the 12th and 13th centuries. The existence of Jomsborg is a matter of debate in historical circles, due to the scarcity of primary sources. There are no contemporary sources mentioning the names Jomsvikings and Jomsborg, but there are three contemporary runestones and several contemporary lausavísur held to refer to one of their battles.
