Gotland

• 1. Introduction

  ›

  Gotland sits roughly 90 km east of the Swedish mainland, an island of limestone and medieval stone at the geographic heart of the Baltic Sea. It is Sweden's largest island, yet it accounts for less than one percent of the country's total land area. What it lacks in size it more than makes up for in depth. People have lived here since approximately 7200 BCE, making it one of the longest continuously inhabited places in northern Europe. Under its fields lie coin hoards containing more Arab silver dirhams than anywhere else in Western Eurasia. Its medieval walled town of Visby is a UNESCO World Heritage Site. Its 94 medieval churches still hold regular services. And in the summer, a population of around 61,000 swells to extraordinary numbers as mainland Swedes pour across the Baltic by ferry and plane. How did a relatively small island become a Viking-era commercial powerhouse, a medieval battleground, and a modern strategic flashpoint all at once? The answer runs through trade silver, Hanseatic merchants, Danish invasions, and a regiment re-established for the first time since World War II.

  A DNA study conducted on 5,000-year-old skeletal remains of three Middle Neolithic seal hunters from Gotland revealed something surprising: they were closely related to modern-day Finns, not to mainland Scandinavians. A farmer from Gökhem parish on the Swedish mainland, by contrast, showed closer genetic ties to modern-day Mediterraneans. The finding fits the broader pattern of agricultural peoples spreading outward from the Middle East at roughly that time, while Gotland's hunter-gatherer population retained a distinct genetic identity.

  The Gutasaga, a collection of legends about the island's origins, names a man called Þieluar as the first settler and traces the descent of the island's people from his descendants. It records that a third of the population had to emigrate southward into Europe, a tradition scholars have long linked to the migration of the Goths. The native name for the island's people, Gutes, shares the same linguistic root as Goths.

  The Gutasaga also records a man named Awair Strabain as the negotiator who arranged a mutual agreement with the king of Sweden, an agreement the text presents as voluntary rather than a conquest. That submission took place before the end of the ninth century. The Anglo-Saxon traveler Wulfstan of Hedeby, writing at around that time, listed Gotland among the territories subject to the Sweons, confirming the political picture the saga describes.

  By the Viking Age, the island's traders had tapped into one of the most lucrative exchange networks in the medieval world: the Silver-Fur Road, which ran between Rus merchants and the Abbasid Caliphate. The silver that flowed through this network found its way into Gotlandic hoards in staggering quantities, helping to fuel commercial networks that reached from northern Europe to the Islamic world.

  On the 16th of July 1999, a metal detector operator working a field at Spillings farm, northwest of Slite, struck something extraordinary. The Spillings Hoard, which emerged from that field, turned out to be the world's largest Viking silver treasure. It was divided into two parts weighing a total of 67 kg, roughly 27 kg and 40 kg. Among those kilograms were approximately 14,000 coins, most of them Islamic in origin, along with about 20 kg of bronze objects and a range of everyday items: glass beads, nails, pottery, iron bands, and parts of tools. The hoard was found almost by accident during filming of a news report for TV4 about illegal treasure hunting on the island. The farmer who owned the land received a finder's fee of over 2 million kronor, equivalent to around US$308,000.

  The Spillings discovery was dramatic, but it was not isolated. Gotland holds more Arab dirhams than any other site in Western Eurasia. The total sum of Islamic silver found across the island's various hoards approaches the total number unearthed across the entire Muslim world. These coins traveled north along the Silver-Fur Road, carried by Rus traders dealing with the Abbasid Caliphate. The profits helped make Viking Scandinavia and the Carolingian Empire major commercial hubs for centuries.

  The reach of Gotland's traders is confirmed by a runestone found in 1905 on the Ukrainian island of Berezan. A Varangian trader named Grani made it in memory of his business partner Karl. Researchers believe both men came from Gotland. The Mästermyr chest, another important Viking-Age artifact, was also found on the island, pointing to a society with sophisticated craft skills alongside its commercial ambitions.

  Visby became the most important Hanseatic city in the Baltic Sea, a commercial hub that drew German merchants from across northern Europe. The city and the rest of the island were governed separately, and that division produced real tension. A civil war broke out between the German merchants in Visby and the rural Gotlandic farmers they traded with. King Magnus III of Sweden had to intervene to put it down in 1288.

  The oldest written law for the island, Gutalagen, was set down around 1220 CE and remained in force until 1645. The island's internal governance ran through twenty district courts, each called a ting, with elected judges representing their districts at the island-wide landsting. New laws and major decisions flowed through this assembly.

  In 1361, Valdemar Atterdag of Denmark invaded. Around 1,500 Gotlandic farmers were killed by Danish forces after gathering to fight at the Battle of Mästerby. The island then passed through a succession of outside hands. The Victual Brothers, a confederation that operated somewhere between piracy and mercenary enterprise, occupied Visby in 1394 and used it as a stronghold. To dislodge them, Gotland was granted as a fief to the Teutonic Knights on the condition that they expel the pirates. A Teutonic army conquered the island in 1398, destroying Visby in the process and driving the Victual Brothers out.

  In 1409, Grand Master Ulrich von Jungingen sold Gotland to Queen Margaret of Denmark, Norway and Sweden, buying peace with the Kalmar Union. The landsting's authority steadily eroded afterward, first under the Teutonic Order and then under Danish governors appointed after 1449. The Treaty of Brömsebro in 1645 finally settled the island under Swedish rule, where it has remained since.

  ›

  On the 22nd of April 1808, during the Finnish War fought between Sweden and Russia, a Russian army landed on the southeastern shores of Gotland near Grötlingbo. The force, under the command of Nikolai Andreevich Bodisko, numbered 1,800 men. They took the city of Visby without any combat and occupied the island.

  Sweden responded by dispatching a naval rescue expedition from Karlskrona under Admiral Rudolf Cederström, bringing 2,000 men. The island was liberated, and the Russian forces capitulated. They left Gotland on the 18th of May 1808, less than a month after landing.

  Two years before the Russian landing, on the 19th of September 1806, King Gustav IV Adolf had offered the sovereignty of Gotland to the Order of St. John of Jerusalem, which had been expelled from Malta in 1798. The Order declined. Accepting would have meant formally renouncing their claim to Malta, which they were unwilling to do. The Order never recovered its original territory and eventually reestablished itself in Rome as the Sovereign Military Order of Malta.

  ›

  In March 2015, the Swedish government announced it would begin rebuilding a permanent military presence on Gotland, starting with an initial garrison of 150 troops drawn primarily from the Swedish Army. That followed a period of vulnerability: the island had no local air defence capability, no naval units, and its only remaining military asset was 14 Stridsvagn 122 tanks stored at the Tofta firing range without assigned crews or maintenance personnel.

  The Tofta firing range, located 8 km south of Visby, dates its origins to 1898 and extends over 2,700 acres. It had served as the Gotland garrison's main training and storage facility until the garrison was shut down in 2005. From the second half of 2014, armored units began using the range more frequently as tensions in northeastern Europe escalated.

  The Gotland Regiment was re-established in 2018, the first time since World War II that a new regiment had been created anywhere in Sweden. Following the 2022 Russian invasion of Ukraine and Sweden's subsequent accession to NATO, military spending on the island accelerated sharply. The Swedish government committed 150 million euros to expand military infrastructure on Gotland, reflecting the island's position at the center of the Baltic Sea as a factor of growing strategic consequence.

  The Tofta range also hosted the Gotland Grand National, described as the world's largest enduro race, from 1984 to 2023, a reminder that the same land carries multiple identities simultaneously.

  Gotland's 94 medieval churches represent one of the highest concentrations of medieval ecclesiastical architecture in northern Europe, and most remain in active use. The oldest were built in the Romanesque style between 1150 and 1250. The newer ones followed the Gothic style that dominated from around 1250 to 1400. The oldest painting inside any of these churches dates to the 12th century.

  The fortress wall surrounding the old city of Visby dates from the 13th century. That medieval town is now part of the UNESCO World Heritage programme. Visby also hosts two major annual events that draw visitors from across Sweden: Almedalen Week, a political gathering, followed immediately by Medieval Week.

  Spread across the island are roughly 3,700 grinding grooves cut into rock, approximately 750 of them in solid limestone outcrops and the rest in formations ranging from granite and gneiss to sandstone. Archaeologists read them as evidence of an unknown industrial process from the High Middle Ages. Astronomer Göran Henriksson has argued that some date to the Stone Age based on astronomical alignments, though his methodology has drawn criticism.

  Traditional games called Gutniska Lekar, including Kubb, Pärk, and Varpa, are still played on the island, particularly during Midsummer's Eve. Some of these games have spread to players as far away as the United States. Gotland also gives its name to Gotlandsdricka, a traditional farmhouse ale described as turbid, with close similarities to Finnish sahti and related Baltic-state beers. For the 1989 Studio Ghibli film Kiki's Delivery Service, director Hayao Miyazaki and other illustrators traveled to Gotland in preparation for the animation, drawing on the island's visual character for the film's setting.
