Why Did Greenland’s Vikings Vanish?

On the grassy slope of a fjord near the southernmost tip of Greenland
stand the ruins of a church built by Viking settlers more than a century
before Columbus sailed to the Americas. The thick granite-block walls
remain intact, as do the 20-foot-high gables. The wooden roof, rafters
and doors collapsed and rotted away long ago. Now sheep come and go at
will, munching wild thyme where devout Norse Christian converts once
knelt in prayer.

Vikings : The North Atlantic Saga

The Vikings called this fjord Hvalsey, which means “Whale Island” in Old
Norse. It was here that Sigrid Bjornsdottir wed Thorstein Olafsson on
Sunday, September 16, 1408. The couple had been sailing from Norway to
Iceland when they were blown off course; they ended up settling in
Greenland, which by then had been a Viking colony for some 400 years.
Their marriage was mentioned in three letters written between 1409 and
1424, and was then recorded for posterity by medieval Icelandic scribes.
Another record from the period noted that one person had been burned at
the stake at Hvalsey for witchcraft.

But the documents are most remarkable—and baffling—for what they don’t
contain: any hint of hardship or imminent catastrophe for the Viking
settlers in Greenland, who’d been living at the very edge of the known
world ever since a renegade Icelander named Erik the Red arrived in a
fleet of 14 longships in 985. For those letters were the last anyone
ever heard from the Norse Greenlanders.

They vanished from history.

“If there was trouble, we might reasonably have thought that there would
be some mention of it,” says Ian Simpson, an archaeologist at the
University of Stirling, in Scotland. But according to the letters, he
says, “it was just an ordinary wedding in an orderly community.”

Europeans didn’t return to Greenland until the early 18th century. When
they did, they found the ruins of the Viking settlements but no trace of
the inhabitants. The fate of Greenland’s Vikings—who never numbered more
than 2,500—has intrigued and confounded generations of archaeologists.

Those tough seafaring warriors came to one of the world’s most
formidable environments and made it their home. And they didn’t just get
by: They built manor houses and hundreds of farms; they imported stained
glass; they raised sheep, goats and cattle; they traded furs,
walrus-tusk ivory, live polar bears and other exotic arctic goods with
Europe. “These guys were really out on the frontier,” says Andrew
Dugmore, a geographer at the University of Edinburgh. “They’re not just
there for a few years. They’re there for generations—for centuries.”

So what happened to them?

**********

Thomas McGovern used to think he knew. An archaeologist at Hunter
College of the City University of New York, McGovern has spent more than
40 years piecing together the history of the Norse settlements in
Greenland. With his heavy white beard and thick build, he could pass for
a Viking chieftain, albeit a bespectacled one. Over Skype, here’s how he
summarized what had until recently been the consensus view, which he
helped establish: “Dumb Norsemen go into the north outside the range of
their economy, mess up the environment and then they all die when it
gets cold.”

Thomas McGovern
Thomas McGovern (with Viking-era animal bones): The Greenlanders’ end
was “grim.” (Reed Young)
Accordingly, the Vikings were not just dumb, they also had dumb luck:
They discovered Greenland during a time known as the Medieval Warm
Period, which lasted from about 900 to 1300. Sea ice decreased during
those centuries, so sailing from Scandinavia to Greenland became less
hazardous. Longer growing seasons made it feasible to graze cattle,
sheep and goats in the meadows along sheltered fjords on Greenland’s
southwest coast. In short, the Vikings simply transplanted their
medieval European lifestyle to an uninhabited new land, theirs for the
taking.

But eventually, the conventional narrative continues, they had problems.
Overgrazing led to soil erosion. A lack of wood—Greenland has very few
trees, mostly scrubby birch and willow in the southernmost
fjords—prevented them from building new ships or repairing old ones. But
the greatest challenge—and the coup de grâce—came when the climate began
to cool, triggered by an event on the far side of the world.

In 1257, a volcano on the Indonesian island of Lombok erupted.
Geologists rank it as the most powerful eruption of the last 7,000
years. Climate scientists have found its ashy signature in ice cores
drilled in Antarctica and in Greenland’s vast ice sheet, which covers
some 80 percent of the country. Sulfur ejected from the volcano into the
stratosphere reflected solar energy back into space, cooling Earth’s
climate. “It had a global impact,” McGovern says. “Europeans had a long
period of famine”—like Scotland’s infamous “seven ill years” in the
1690s, but worse. “The onset was somewhere just after 1300 and continued
into the 1320s, 1340s. It was pretty grim. A lot of people starving to
death.”

Amid that calamity, so the story goes, Greenland’s Vikings—numbering
5,000 at their peak—never gave up their old ways. They failed to learn
from the Inuit, who arrived in northern Greenland a century or two after
the Vikings landed in the south. They kept their livestock, and when
their animals starved, so did they. The more flexible Inuit, with a
culture focused on hunting marine mammals, thrived.

That is what archaeologists believed until a few years ago. McGovern’s
own PhD dissertation made the same arguments. Jared Diamond, the UCLA
geographer, showcased the idea in Collapse, his 2005 best seller about
environmental catastrophes. “The Norse were undone by the same social
glue that had enabled them to master Greenland’s difficulties,” Diamond
wrote. “The values to which people cling most stubbornly under
inappropriate conditions are those values that were previously the
source of their greatest triumphs over adversity.”

But over the last decade a radically different picture of Viking life in
Greenland has started to emerge from the remains of the old settlements,
and it has received scant coverage outside of academia. “It’s a good
thing they can’t make you give your PhD back once you’ve got it,”
McGovern jokes. He and the small community of scholars who study the
Norse experience in Greenland no longer believe that the Vikings were
ever so numerous, or heedlessly despoiled their new home, or failed to
adapt when confronted with challenges that threatened them with
annihilation.

“It’s a very different story from my dissertation,” says McGovern. “It’s
scarier. You can do a lot of things right—you can be highly adaptive;
you can be very flexible; you can be resilient—and you go extinct
anyway.” And according to other archaeologists, the plot thickens even
more: It may be that Greenland’s Vikings didn’t vanish, at least not all
of them.

**********

Lush grass now covers most of what was once the most important Viking
settlement in Greenland. Gardar, as the Norse called it, was the
official residence of their bishop. A few foundation stones are all that
remain of Gardar’s cathedral, the pride of Norse Greenland, with stained
glass and a heavy bronze bell. Far more impressive now are the nearby
ruins of an enormous barn. Vikings from Sweden to Greenland measured
their status by the cattle they owned, and the Greenlanders spared no
effort to protect their livestock. The barn’s Stonehenge-like partition
and the thick turf and stone walls that sheltered prized animals during
brutal winters have endured longer than Gardar’s most sacred architecture.

Disko Bay

in Disko Bay. (Guilbert Gates)
Gardar’s ruins occupy a small fenced-in field abutting the backyards of
Igaliku, an Inuit sheep-farming community of about 30 brightly painted
wooden houses overlooking a fjord backed by 5,000-foot-high snowcapped
mountains. No roads run between towns in Greenland—planes and boats are
the only options for traversing a coastline corrugated by innumerable
fjords and glacial tongues. On an uncommonly warm and bright August
afternoon, I caught a boat from Igaliku with a Slovenian photographer
named Ciril Jazbec and rode a few miles southwest on Aniaaq fjord, a
region Erik the Red must have known well. Late in the afternoon, with
the arctic summer sun still high in the sky, we got off at a rocky beach
where an Inuit farmer named Magnus Hansen was waiting for us in his
pickup truck. After we loaded the truck with our backpacks and essential
supplies requested by the archaeologists—a case of beer, two bottles of
Scotch, a carton of menthol cigarettes and some tins of snuff—Hansen
drove us to our destination: a Viking homestead being excavated by
Konrad Smiarowski, one of McGovern’s doctoral students.

The homestead lies at the end of a hilly dirt road a few miles inland on
Hansen’s farm. It’s no accident that most modern Inuit farms in
Greenland are found near Viking sites: On our trip down the fjord, we
were told that every local farmer knows the Norse chose the best
locations for their homesteads.

The Vikings established two outposts in Greenland: one along the fjords
of the southwest coast, known historically as the Eastern Settlement,
where Gardar is located, and a smaller colony about 240 miles north,
called the Western Settlement. Nearly every summer for the last several
years, Smiarowski has returned to various sites in the Eastern
Settlement to understand how the Vikings managed to live here for so
many centuries, and what happened to them in the end.

This season’s site, a thousand-year-old Norse homestead, was once part
of a vital community. “Everyone was connected over this huge landscape,”
Smiarowski says. “If we walked for a day we could visit probably 20
different farms.”

He and his team of seven students have spent several weeks digging into
a midden—a trash heap—just below the homestead’s tumbled ruins. On a
cold, damp morning, Cameron Turley, a PhD candidate at the City
University of New York, stands in the ankle-deep water of a drainage
ditch. He’ll spend most of the day here, a heavy hose draped over his
shoulder, rinsing mud from artifacts collected in a wood-framed sieve
held by Michalina Kardynal, an undergraduate from Cardinal Stefan
Wyszynski University in Warsaw. This morning they’ve found a delicate
wooden comb, its teeth intact. They’re also finding seal bones. Lots of
them.

“Probably about 50 percent of all bones at this site will be seal
bones,” Smiarowski says as we stand by the drainage ditch in a light
rain. He speaks from experience: Seal bones have been abundant at every
site he has studied, and his findings have been pivotal in reassessing
how the Norse adapted to life in Greenland. The ubiquity of seal bones
is evidence that the Norse began hunting the animals “from the very
beginning,” Smiarowski says. “We see harp and hooded seal bones from the
earliest layers at all sites.”

A seal-based diet would have been a drastic shift from
beef-and-dairy-centric Scandinavian fare. But a study of human skeletal
remains from both the Eastern and Western settlements showed that the
Vikings quickly adopted a new diet. Over time, the food we eat leaves a
chemical stamp on our bones—marine-based diets mark us with different
ratios of certain chemical elements than terrestrial foods do. Five
years ago, researchers based in Scandinavia and Scotland analyzed the
skeletons of 118 individuals from the earliest periods of settlement to
the latest. The results perfectly complement Smiarow­ski’s fieldwork:
Over time, people ate an increasingly marine diet, he says.

It’s raining heavily now, and we’re huddled beneath a blue tarp next to
the midden, sipping coffee and ingesting some terrestrial chemical
elements in the form of cookies. In the earliest days of the
settlements, Smiarowski says, the study found that marine animals made
up 30 to 40 percent of the Norse diet. The percentage steadily climbed,
until, by the end of the settlement period, 80 percent of the Norse diet
came from the sea. Beef eventually became a luxury, most likely because
the volcano-induced climate change made it vastly more difficult to
raise cattle in Greenland.

Judging from the bones Smiarowski has uncovered, most of the seafood
consisted of seals—few fish bones have been found. Yet it appears the
Norse were careful: They limited their hunting of the local harbor seal,
Phoca vitulina, a species that raises its young on beaches, making it
easy prey. (The harbor seal is critically endangered in Greenland today
due to overhunting.) “They could have wiped them out, and they didn’t,”
Smiarowski says. Instead, they pursued the more abundant—and more
difficult to catch—harp seal, Phoca groenlandica, which migrates up the
west coast of Greenland every spring on the way from Canada. Those
hunts, he says, must have been well-organized communal affairs, with the
meat distributed to the entire settlement—seal bones have been found at
homestead sites even far inland. The regular arrival of the seals in the
spring, just when the Vikings’ winter stores of cheese and meat were
running low, would have been keenly anticipated.

The last news of Greenland’s Vikings came from Hvalsey. (Ciril Jazbec)
“People came from different farms; some provided labor, some provided
boats,” Smiarowski says, speculating. “Maybe there were several centers
organizing things along the coast of the Eastern Settlement. Then the
catch was divided among the farms, I would assume according to how much
each farm contributed to the hunt.” The annual spring seal hunt might
have resembled communal whale hunts practiced to this day by the Faroe
Islanders, who are the descendants of Vikings.

The Norse harnessed their organizational energy for an even more
important task: annual walrus hunts. Smiarowski, McGovern and other
archaeologists now suspect that the Vikings first traveled to Greenland
not in search of new land to farm—a motive mentioned in some of the old
sagas—but to acquire walrus-tusk ivory, one of medieval Europe’s most
valuable trade items. Who, they ask, would risk crossing hundreds of
miles of arctic seas just to farm in conditions far worse than those at
home? As a low-bulk, high-value item, ivory would have been an
irresistible lure for seafaring traders.

Many ivory artifacts from the Middle Ages, whether religious or secular,
were carved from walrus tusks, and the Vikings, with their ships and
far-flung trading networks, monopolized the commodity in Northern
Europe. After hunting walruses to extinction in Iceland, the Norse must
have sought them out in Greenland. They found large herds in Disko Bay,
about 600 miles north of the Eastern Settlement and 300 miles north of
the Western Settlement. “The sagas would have us believe that it was
Erik the Red who went out and explored [Greenland],” says Jette
Arneborg, a senior researcher at the National Museum of Denmark, who,
like McGovern, has studied the Norse settlements for decades. “But the
initiative might have been from elite farmers in Iceland who wanted to
keep up the ivory trade—it might have been in an attempt to continue
this trade that they went farther west.”

Smiarowski and other archaeologists have unearthed ivory fragments at
nearly every site they’ve studied. It seems the Eastern and Western
settlements may have pooled their resources in an annual walrus hunt,
sending out parties of young men every summer. “An individual farm
couldn’t do it,” he says. “You would need a really good boat and a crew.
And you need to get there. It’s far away.” Written records from the
period mention sailing times of 27 days to the hunting grounds from the
Eastern Settlement and 15 days from the Western Settlement.

To maximize cargo space, the walrus hunters would have returned home
with only the most valuable parts of the animal—the hides, which were
fashioned into ships’ rigging, and parts of the animals’ skulls. “They
did the extraction of the ivory here on-site,” Smiarowski says. “Not
that many actually on this site here, but on most other sites you have
these chips of walrus maxilla [the upper jaw]—very dense bone. It’s
quite distinct from other bones. It’s almost like rock—very hard.”

Jazbec)
How profitable was the ivory trade? Every six years, the Norse in
Greenland and Iceland paid a tithe to the Norwegian king. A document
from 1327, recording the shipment of a single boatload of tusks to
Bergen, Norway, shows that that boatload, with tusks from 260 walruses,
was worth more than all the woolen cloth sent to the king by nearly
4,000 Icelandic farms for one six-year period.

Archaeologists once assumed that the Norse in Greenland were primarily
farmers who did some hunting on the side. Now it seems clear that the
reverse was true. They were ivory hunters first and foremost, their
farms only a means to an end. Why else would ivory fragments be so
prevalent among the excavated sites? And why else would the Vikings send
so many able-bodied men on hunting expeditions to the far north at the
height of the farming season? “There was a huge potential for ivory
export,” says Smiarowski, “and they set up farms to support that.” Ivory
drew them to Greenland, ivory kept them there, and their attachment to
that toothy trove may be what eventually doomed them.

**********

When the Norse arrived in Greenland, there were no locals to teach them
how to live. “The Scandinavians had this remarkable ability to colonize
these high-latitude islands,” says Andrew Dugmore. “You have to be able
to hunt wild animals; you have to build up your livestock; you have to
work hard to exist in these areas....This is about as far as you can
push the farming system in the Northern Hemisphere.”

And push it they did. The growing season was short, and the land
vulnerable to overgrazing. Ian Simpson has spent many seasons in
Greenland studying soil layers where the Vikings farmed. The strata, he
says, clearly show the impact of their arrival: The earliest layers are
thinner, with less organic material, but within a generation or two the
layers stabilized and the organic matter built up as the Norse farmwomen
manured and improved their fields while the men were out hunting. “You
can interpret that as being a sign of adaptation, of them getting used
to the landscape and being able to read it a little better,” Simpson says.

For all their intrepidness, though, the Norse were far from
self-sufficient, and imported grains, iron, wine and other essentials.
Ivory was their currency. “Norse society in Greenland couldn’t survive
without trade with Europe,” says Arneborg, “and that’s from day one.”

Then, in the 13th century, after three centuries, their world changed
profoundly. First, the climate cooled because of the volcanic eruption
in Indonesia. Sea ice increased, and so did ocean storms—ice cores from
that period contain more salt from oceanic winds that blew over the ice
sheet. Second, the market for walrus ivory collapsed, partly because
Portugal and other countries started to open trade routes into
sub-Saharan Africa, which brought elephant ivory to the European market.
“The fashion for ivory began to wane,” says Dugmore, “and there was also
the competition with elephant ivory, which was much better quality.” And
finally, the Black Death devastated Europe. There is no evidence that
the plague ever reached Greenland, but half the population of
Norway—which was Greenland’s lifeline to the civilized world—perished.

The Norse probably could have survived any one of those calamities
separately. After all, they remained in Greenland for at least a century
after the climate changed, so the onset of colder conditions alone
wasn’t enough to undo them. Moreover, they were still building new
churches—like the one at Hvalsey—in the 14th century. But all three
blows must have left them reeling. With nothing to exchange for European
goods—and with fewer Europeans left—their way of life would have been
impossible to maintain. The Greenland Vikings were essentially victims
of globalization and a pandemic.

“If you consider the world today, many communities will face exposure to
climate change,” says Dugmore. “They’ll also face issues of
globalization. The really difficult bit is when you have exposure to both.”

**********

So what was the endgame like in Greenland? Although archaeologists now
agree that the Norse did about as well as any society could in
confronting existential threats, they remain divided over how the
Vikings’ last days played out. Some believe that the Norse, faced with
the triple threat of economic collapse, pandemic and climate change,
simply packed up and left. Others say the Norse, despite their adaptive
ingenuity, met a far grimmer fate.

For McGovern, the answer is clear. “I think in the end this was a real
tragedy. This was the loss of a small community, a thousand people maybe
at the end. This was extinction.”

The Norse, he says, were especially vulnerable to sudden death at sea.
Revised population estimates, based on more accurate tallies of the
number of farms and graves, put the Norse Greenlanders at no more than
2,500 at their peak—less than half the conventional figure. Every spring
and summer, nearly all the men would be far from home, hunting. As
conditions for raising cattle worsened, the seal hunts would have been
ever more vital—and more hazardous. Despite the decline of the ivory
trade, the Norse apparently continued to hunt walrus until the very end.
So a single storm at sea could have wiped out a substantial number of
Greenland’s men—and by the 14th century the weather was increasingly
stormy. “You see similar things happening at other places and other
times,” McGovern says. “In 1881, there was a catastrophic storm when the
Shetland fishing fleet was out in these little boats. In one afternoon
about 80 percent of the men and boys of the Shetlands drowned. A whole
bunch of little communities never recovered.”

Erik the Red slept here: Qassiarsuk features replicas of a Viking church
and longhouse. (Ciril Jazbec)
Norse society itself comprised two very small communities: the Eastern
and Western settlements. With such a sparse population, any loss—whether
from death or emigration—would have placed an enormous strain on the
survivors. “If there weren’t enough of them, the seal hunt would not be
successful,” says Smiarowski. “And if it was not successful for a couple
of years in a row, then it would be devastating.”

McGovern thinks a few people might have migrated out, but he rules out
any sort of exodus. If Greenlanders had emigrated en masse to Iceland or
Norway, surely there would have been a record of such an event. Both
countries were literate societies, with a penchant for writing down
important news. “If you had hundreds or a thousand people coming out of
Greenland,” McGovern says, “someone would have noticed.”

Niels Lynnerup, a forensic anthropologist at the University of
Copenhagen who has studied Viking burial sites in Greenland, isn’t so
sure. “I think in Greenland it happened very gradually and
undramatically,” he tells me as we sit in his office, beneath a poster
of the Belgian cartoon character Tintin. “Maybe it’s the usual human
story. People move to where there are resources. And they move away when
something doesn’t work for them.” As for the silence of the historical
record, he says, a gradual departure might not have attracted much
attention.

The ruins themselves hint at an orderly departure. There is no evidence
of conflict with the Inuit or of any intentional damage to homesteads.
And aside from a gold ring found on the skeletal finger of a bishop at
Gardar, and his narwhal-tusk staff, no items of real value have been
found at any sites in Greenland. “When you abandon a small settlement,
what do you take with you? The valuables, the family jewelry,” says
Lynnerup. “You don’t leave your sword or your good metal knife....You
don’t abandon Christ on his crucifix. You take that along. I’m sure the
cathedral would have had some paraphernalia—cups, candelabras—which we
know medieval churches have, but which have never been found in Greenland.”

Jette Arneborg and her colleagues found evidence of a tidy leave-taking
at a Western Settlement homestead known as the Farm Beneath the Sands.
The doors on all but one of the rooms had rotted away, and there were
signs that abandoned sheep had entered those doorless rooms. But one
room retained a door, and it was closed. “It was totally clean. No sheep
had been in that room,” says Arneborg. For her, the implications are
obvious. “They cleaned up, took what they wanted, and left. They even
closed the doors.”

Perhaps the Norse could have toughed it out in Greenland by fully
adopting the ways of the Inuit. But that would have meant a complete
surrender of their identity. They were civilized Europeans—not
skraelings, or wretches, as they called the Inuit. “Why didn’t the Norse
just go native?” Lynnerup asks. “Why didn’t the Puritans just go native?
But of course they didn’t. There was never any question of the Europeans
who came to America becoming nomadic and living off buffalo.”

We do know that at least two people made it out of Greenland alive:
Sigrid Bjornsdottir and Thorstein Olafsson, the couple who married at
Hvalsey’s church. They eventually settled in Iceland, and in 1424, for
reasons lost to history, they needed to provide letters and witnesses
proving that they had been married in Greenland. Whether they were among
a lucky few survivors or part of a larger immigrant community may remain
unknown. But there’s a chance that Greenland’s Vikings never vanished,
that their descendants are with us still.
