Episode Description from the Publisher

We can decide to stay home, but even then, the wider world is always close to our skin. From global trade to ideas that travel across continents, the wider world is always woven into our modern life.Since when has this been the case?There is a modern story about globalisation — a story about telecommunications and aeroplanes and such — but this is the climax of a long process, not its beginning. To find the deeper roots of globalisation, we should turn our gaze to the medieval world, and specifically to events around the year 1000.Or so argues historian Valerie Hansen.In this episode, we discuss the various curious developments around the year 1000 that began to connect the world into an interconnected web. From Viking explorers to the Silk Roads in Africa, Hansen offers many fascinating windows into the surprising connections that were already beginning to link the medieval world together. We also discuss the spread of inventions and world religions, as well as the deeper forces that Hansen thinks have long been driving world history.Enjoy!FACT-CHECKINGNo errors have been detected in this conversation.
