Around 985AD, Erik the Red founded Norse communities in Greenland after his exile from Iceland that thrived for centuries. However, it did not last as it vanished in the 1400s only leaving ruins as seen today in Greenland.

Artifacts found from this civilization revealed many walrus ivory sculptures, which provide evidence of a trade network that once extended from Northern America to the Mediterranean. 

The Norse communities were able to forge a lucrative economic mainstay in Greenland despite its harsh environmental conditions, Discover reported. Theories about why Norse communities in the area abandoned it is because of climate change with the climate growing colder.

But studies published in the last five years, particularly the 2019 study of the researchers from the universities of Cambridge, Oslo, and Trondheim, found that the Norse communities did not disappear due to climate, but because of the increasing unstable walrus ivory trade.

Walrus Ivory Trade Went From Being a Blessing to Becoming a Curse

A thousand years ago, walrus ivory was a valuable medieval commodity used by the Norse communities in Greenland to trade with those from Europe. Norse in Greenland carved ornate crucifixes, pieces for games like chess, and hnefatafl made from walrus ivory. Even the famous Lewis chessmen were also made of walrus ivory.

However, the study said that this trade slowly went from an economic blessing to become a curse. James H. Barrett, an archaeologist at the University of Cambridge and lead author of the study, and his team found that the ivory came from smaller animals, often female, as time wore on.

They tested the bones and found that some of it could even come from ever farther north, which means they must have voyaged for longer periods of time in dangerous journeys but a lesser reward.

"This really cranks up the amount of danger they are facing," said Tom McGovern, an archaeologist from Hunter College in New York who was not part of Barrett's research team.

Science Daily reported that the increasing elephant ivory trade that flooded the European markets during the 13th century, and changes in fashion have led to the decrease in demand for walrus ivory. By the 1400s, walrus ivory imports to mainland Europe have slowly faded.

Barrett said that the Norse abandonment in Greenland may have been due to the depleted resources and volatile prices that were worsened by climate change.

Overhunting of Walrus and the End of an Era

The mysterious disappearance of the Norse in Greenland in the 1400s is attributed to the overhunting of walrus populations for their tusks.

According to the study, published in Quaternary Science Reviews, Norse Greenlanders mainly had walrus products that they used to trade iron and timber with Europe. But the decreasing values of walrus ivory in the European continent meant that more tusks were harvested to keep the Norse Greenland colonies economically viable.

Barrett said that the overhauling could end the use of traditional haul-out sites by walruses. The Norse hunters were forced to venture into the deeper parts of the Arctic region for meager ivory harvests, exacerbating the decline of walrus populations and subsequently the walrus ivory trade.

According to Discover, the decline of the most important resource the Norse Greenlanders depended on, may not have been able to support themselves and so they had to find a new way to make a living. Thus, the abandonment of their settlement in Greenland.

But since there are no written records that detail the end of the colonies, it remains a mystery whether they sailed back to Europe or died off in the place where they lived for nearly 500 years.
