What is the history of the Panama Canal and why does Trump think he can 'take it back'? Dan is joined by Professor Julie Greene to delve into the long backstory of this 50-mile waterway that changed the world. Its journey from concept to completion was fraught as many nations sought to build it over several centuries, with the US eventually taking up the costly task in the 1900s. During the decade-long construction, many workers, mostly from the Caribbean, suffered awful working conditions and were injured or died building it. Total control was handed over to Panama in the 1990s.

Better understand the headlines with this deep dive into history.

You can learn more in Julie's books 'Box 25: Archival Secrets, Caribbean Workers, and the Panama Canal' and 'The Canal Builders.'

Napoleon Bonaparte is a household name; a rare example of someone who is as well remembered by his supporters as by his enemies. His life is rich with dramatic irony. He was a key figure in the creation of the First French Republic, yet became a self-appointed Emperor. Surrounded by enemies, he secured peace in France through war abroad and was hated by the monarchies of Europe, who feared he would bring democracy to their lands. 

Dan was recently a guest on the Echoes of History podcast, hosted by Matt Lewis, to discuss the life of Napoleon which he's sharing here for DSHH fans to enjoy.

It sounds outlandish that President-Elect Donald Trump has said he wants to buy Greenland but this isn't the first or even second time the United States has tried to acquire this arctic territory. Dan is joined by Professor Robert Rix from the University of Copenhagen to trace the long history of settlement in Greenland - from the Indigenous Inuit to the Norse colonisers and the American soldiers stationed there in the Second World War. Trump might want to buy Greenland, but it isn't necessarily Denmark's to sell...

You can discover more about the history of Greenland in Robert's book 'The Vanished Settlers of Greenland: In Search of a Legend and Its Legacy'.

In 9 AD, the rebel chieftain Arminius and his confederation of Germanic tribes ambushed three Roman legions in the Teutoburg Forest. For days the Romans were relentlessly stalked through the woods and pounced on by their pursuers. All told, up to 20,000 Romans were killed in the chaos, and only a handful were able to escape. The battle proved to be one of Rome's most devastating defeats, and left a scar in the Roman psyche for generations to come.

In this Explainer episode, Dan explores the historical context for the battle and its profound consequences for Roman strategy and expansion. He's helped by Dr. Simon Elliott, who provides deeper insights into how the Roman military worked, and where its vulnerabilities lay.

Warning: this episode contains accounts of violence that some listeners may find disturbing.

In the dead of winter, 1944, the frozen forest of Ardennes erupted in chaos. In a desperate, last-ditch attempt to turn the tide of the war, Hitler threw his armoured divisions at the thinly spread Allied frontline. The battle that followed was the bloodiest fought by the Americans in the war, and their determined defence helped to seal the fate of Nazi Germany.

For the latest instalment in our 'D-Day to Berlin' series, Dan is joined by Professor John C. McManus, author of 'Alamo in the Ardennes'. They delve into this fierce German winter offensive in terms of its strategic significance, and the tenacity of the American soldiers that thwarted Hitler's plans.

Written by Dan Snow, produced by James Hickmann and edited by Dougal Patmore.
