Long distance trade

We often think that ancient people lived in separation with little contacts to humans living in other parts of the world. This view is, however, incorrect because trade has been more or less global for thousands of years.

I wrote in May about ivory trade between Greenland and what is today Ukraine in medieval times. And last week I noticed a new scientific investigation showing that a Late Bronze Age shipwreck - from 3 300 years ago - found off the Turkish coast carried tin ingots, of which one third was produced of ores from Central Asia, thousands of kilometers from shipwrecks location. 

The finding added evidence on a vast, disparate and culturally diverse network of trade that relied as much on the participation of small regional communities as on large, centralized states during the Late Bronze Age. And which formed a basis for the economic development that ultimately - during the following millenia - led to the current world based on global trade and cultural exchange forming the basis of the current way of living throughout the world.

Ivory trade from Greenland to Ukraine

Vikings settled on the uninhabited southwestern coast of Greenland thousand years ago. That was enabled by a technological innovation that allowed them to use wooden ships in long distance sailing. However, after just few centuries the early settlements along the southwestern coast disappeared. 

The reason for the disappearance of Norse has thereafter remained a mystery. The explanations presented include cumulative environmental damage, gradual climate change, conflicts with Inuit peoples, loss of contact and support from Europe, cultural conservatism and failure to adapt to an increasingly harsh natural environment and opening of opportunities elsewhere after the black death had left many farmsteads abandoned in Iceland and Norway as well as declining value of ivory in Europe.

The last option was based on the fact that some Vikings are known to have organised summer trips to the more northerly area, where they hunted walruses, narwhals and polar bears for their skins, hides and ivory. Besides their use in making garments and shoes, these resources also functioned as a form of currency, as well as providing the most important export commoditie.

Recently it was reported in Science that Vikings shipped walrus ivory all the way to Kyiv, the capital of today´s Ukraine. This trade route is much longer than was thought based on previous studies - up to 4 000 km. This information was worked out by DNA and chemical analyses, which linked Ukrainian walrus tusk materials to a genetic group of walruses found only in the western Atlantic Ocean. 

The trade was obviously highly profitable, and may have lead to overhunting of Greenlandic walruses, due to the consumer demand in Eastern Europe. That seems to strengthen the hypothesis that Norse settlers abandoned Greenland in the 1300s at least partly due to the ending ivory trade.

This finding is just one of the historical facts that shows how medieval people had connections over long distances. And partially highlights how incorrect we are, if we consider our time as completely unique in its global connections and trade. Instead of qualitative differences, the change is only quantitative. That is, in the speed that allows us to make contacts throughout the world.
