The Jomswikings were a legendary Viking band of mercenaries in the area of the southern (possibly the now part of Poland) Baltic coast. The Old Norse Jómsvíkinga saga tells of the rise and fall of the dreaded alliance of men with strict regulations.

"No man was to be admitted here older than fifty, and none younger than eighteen. In between should be all. Consanguinity was not to play a balancing role in admitting men who did not conform to the laws. No man was to flee from one equally belligerent and equally armed. Each was to avenge the other as his brother. No man should speak a word of fear or despair in any situation, however hopeless it seemed. They were to bring to the bar all that they had captured on their military journeys, inferior or greater goods that had monetary value. And if one of them did not do so, he would have to leave. No one was to bring a slander. But if any news were to become known, no one should be so bold as to tell it publicly; for Palnatoki was to announce all the news there. No one should have a wife in the castle, and no one should be out more than three nights. And if a man was taken in who had slain the father or brother of a man who had been there before, or any other related man, and this came out later after he was taken in, Palnatoki was to decide all this, and so also with any other disagreement that arose among them."

- Walter Baetke: Jómsvíkinga saga

Their seat is said to have been the Jomsborg, whose location is assumed to be either on the island of Wollin or at the mouth of the Peene River on the island of Usedom.

The harbor of that time was said to be able to accommodate 300 longships. The place is also considered the "Atlantis of the North", where the sunken city of Vineta was located.

According to the Old Norse sources, a large part of the Jomswikings followed the Swedish pretender to the throne, Styrbjörn, and fell together with Styrbjörn in the battle of Fýrisvellir against the Swedes in 983 or 986.

Against the Norwegians, the Jomswikings lost the battle of Hjørungavåg in 994, which is said to have sealed their downfall. Nevertheless, they are said to have participated in the naval battle of Svold as late as the year 1000.

It is believed that the Jomsvikinga saga is largely fiction. However, it can be assumed that the described mercenary league actually existed, as other sagas and documents of the time refer to it.

During the National Socialist era, the saga was widely received and translated because of its references to the Männerbund theory. Thus, between 1934 and 1939, no fewer than eight translations were produced from Old Icelandic into German.

In reference to the historical-legendary Viking Men's League, numerous Living History groups have named themselves after the Jomswikers. The tenth studio album of the Swedish music group Amon Amarth bears the name Jomsviking.
