Globalisation. It's a word we often associate with the politics, society and economics of our own lifetimes. But Valerie Hansen, an esteemed professor of History at Yale, has argued that globalisation is embedded deep in the past. Whilst traditionally, historians have cited Columbus' 1492 voyage to America as a kick off point, Valerie pulls us way back to the year 1000. In this podcast, she reveals how international trade routes already linked the globe, with evidence such as the frozen textiles found in Greenland made of hairs from North American animals. This was a fascinating discussion, proving once again, how history can tell us so much about the contemporary world.
