Overview
A Semi-Legendary Stronghold
Jomsborg, or Jóm borg, represents a semi-legendary Viking stronghold situated on the southern coast of the Baltic Sea, within the historical region known as Wendland, which corresponds to modern-day Pomerania. Its purported existence spans from the 960s to 1043 CE. The inhabitants of this formidable settlement were known as the Jomsvikings, a distinct group of warriors.
Geographical Context
The precise location of Jomsborg remains an enigma, a subject of considerable scholarly debate. While its existence is often maintained, definitive archaeological evidence has yet to firmly establish its whereabouts. A prominent theory places it near the eastern outlet of the Oder River, a strategically significant waterway in the region.
The Debate of Existence
The historical veracity of Jomsborg has been questioned by scholars. Notably, historian Lauritz Weibull posited that Jomsborg might be purely a legendary construct, existing more in sagas and chronicles than in tangible reality. This perspective highlights the challenges in reconciling the rich narratives with the sparse archaeological record.
Location Debates
Wolin: The Primary Candidate
The most frequently cited location for Jomsborg is the present-day town of Wolin (historically known as Wollin) on the southeastern tip of the Isle of Wolin in northwestern Poland. During the Early Middle Ages, this area was a vibrant, multi-ethnic emporium known by names such as Jumne or Julin. Medieval German histories often refer to the site by these names, while Nordic sagas exclusively use "Jómsborg." The possibility exists that these names refer to the same settlement, possibly situated at Srebrna Góra hill north of modern Wolin.
Coastal Theories and Submerged Lands
Alternative theories propose that Jomsborg might have been located on the northwestern part of the nearby island of Usedom, on lands that are now submerged beneath the sea. This region, situated between Usedom and the island of Rügen, was significantly impacted by storm floods in the early 14th century. Suspected sites include the Veritas grounds between the small islands of Ruden and Greifswalder Oie, and the Peenemünde shoals. While Viking Age jewelry has been unearthed in these areas, comprehensive archaeological evaluation remains challenging.
Archaeological Investigations
Recent archaeological discoveries in Wolin, dating to 2023, are currently being investigated as a potential site for Jomsborg. Furthermore, historical records, such as the controversial Gesta Wulinensis ecclesiae pontificum, discovered in 2019, have suggested a precise location near Paprotno, Poland. However, these claims, particularly those associated with the Curmsun Disc and the aforementioned chronicle, have faced scrutiny regarding their provenance and authenticity, with some historians suggesting they may be forgeries due to anachronisms and lack of independent corroboration.
The Fortress
Construction and Design
According to sagas like the Knytlingasaga and Fagrskinna, Jomsborg was established in the 960s by the Danish King Harald Bluetooth, though the Jomsvikinga Saga credits Palnatoki as its founder. Medieval records describe Jomsborg as a fortified settlement featuring a significant harbor. A notable defensive structure mentioned is a stone tower, positioned over the harbor entrance and equipped with catapults. This entrance could be secured by a formidable iron gate.
Harbor Capacity and Significance
The capacity of Jomsborg's harbor is a point of variation in historical accounts. The earliest records suggest it could accommodate approximately three ships. However, later accounts indicate a much larger capacity, potentially housing up to 360 vessels. This suggests a strategic maritime hub, capable of supporting a substantial fleet, which aligns with its reputation as a base for Viking operations.
Destruction
The stronghold's active period concluded dramatically. According to the Heimskringla, Jomsborg was destroyed in 1043 by Magnus the Good, the Dano-Norwegian king. Historical accounts detail that the fortress was burned down, resulting in the demise of many of its inhabitants, marking a definitive end to its era of influence.
The Jomsvikings
Elite Warriors
The Jomsvikings constituted an elite corps of warriors, distinguished by their adherence to a specific code of conduct and their unwavering loyalty solely to their chosen leader. This disciplined military order formed the backbone of Jomsborg's power and influence.
Leadership and Allegiance
Most historical records identify Sigvald(i), son of the petty king Strut-Harald of Scania (a region in modern Denmark), as the Jarl, or leader, of Jomsborg. Sigvald's tenure predated 1010 CE. The strict code of the Jomsvikings ensured a cohesive and formidable fighting force, dedicated to their commander and their shared martial ethos.
Evidence and Controversy
The Curmsun Disc
A significant piece of purported evidence is the Curmsun Disc, a golden artifact discovered in Sweden in 2014. This disc bears a Latin inscription that includes the name "ARALD CVRMSVN+REX AD TANER+SCON+JVMN+CIV ALDIN+", translating to "Harald Gormsson king of Danes, Scania, Jomsborg, diocese of Aldinburg." The disc's provenance is linked to a hoard found in Wiejkowo, Poland, near Wolin, in 1841. However, its unique nature and unclear origins have led to scholarly skepticism.
The Gesta Wulinensis Ecclesiae Pontificum
Following the discovery of the Curmsun Disc, a text surfaced, claimed to be a modern Polish translation of an otherwise unknown Latin chronicle, the Gesta Wulinensis ecclesiae pontificum. This chronicle purportedly provides detailed accounts of the Jomsvikings and Jomsborg, suggesting a location near Paprotno, Poland. However, historians have raised concerns about anachronisms within the text and the lack of independent verification for both the disc and the chronicle, leading some to suspect they may be fabrications.
Scholarly Scrutiny
The claims surrounding the Curmsun Disc and the Gesta Wulinensis have been met with considerable academic criticism. Archaeologists and historians have pointed to the lack of direct access to the artifacts for independent study and the presence of anachronisms in the textual sources. This ongoing debate underscores the difficulty in definitively establishing Jomsborg's existence and precise location based on current evidence.
