Journeys is the topic this episode, which features Mansa Musa - the man so rich he ruined the economy of the Middle East by going on holiday there - a stroke of marketing genius by a viking leader, and quite a lot of references to snooker-based game show Big Break.
Welcome to That Was Genius: A weekly podcast looking at the weirder side of history. Two blokes. A 12-hour time difference. An immature sense of humour. And 10,000 years of human civilisation.
Join Sam Datta-Paulin (he likes history and lives in Britain) and Tom Berry (he also likes history but lives in New Zealand), for a weekly reflection on the bold, the brilliant... And the downright strange.
From bizarre events and stories to equally odd inventions, barely a day goes by without something incredible (or incredibly stupid) happening around the world.
We upload new episodes every Wednesday night (UK time).
That Was Genius is produced by Glorious Republic Broadcasting.
