30YearsWar #61: The Eastern Context 20.07.2022

Sweden's strategic situation was pretty desperate by early 1635, but to appreciate just how desperate it was, we have to look away from the Holy Roman Empire, and towards the East, where in Poland, the truce was about to expire with Sweden's dynastic enemy. Worse, for Swedish Chancellor Axel Oxenstierna, the grand plan of distracting Poland by orchestrating a Russian war had failed as well, leavin...

My Ten Favourite Series 14.07.2022

What's your favourite podcast series under WDF's umbrella? We've covered an awful lot, and a wide range of history, from the obscure, to the famous and infamous, to the shockingly misunderstood. We've come a long way in these ten years, and picking ten of my faves was a difficult task, but after a brutal process of elimination, here it is - complete with music to get you all nostalgic. Do you agre...

My Ten Favourite Historical Figures 11.07.2022

After ten years of history podcasting, I've come across many remarkable and fascinating historical figures, but can I pick a favourite? The task is a difficult one, so to make it easier for myself, I picked ten. Find out here which figures make the cut, as I rank them from number ten all the way down to number one. Did my choices surprise you? Do you feel a particular character was unfairly malign...

Ten Years of When Diplomacy Fails Podcast - A Retrospective 08.07.2022

On 18 May 2012, When Diplomacy Fails Podcast broke into the history podcast scene, and the rest is history! For more than a decade, this show has granted me opportunities and experiences I never dreamed possible. It made me who I am today, from my past jobs, to my education, literally down to where I am professionally and personally right now.  This is the story of how something as simple as...

30YearsWar #60: Richelieu's Last Stand 06.07.2022

As spring 1635 approached, France had a choice to make. She could remain neutral, and allow the Imperial-Spanish triumph to overwhelm the Swedish and Dutch. Or, she could join their struggle, and end once and for the Bourbon-Habsburg cold war that had lasted a generation. It's decision time for Cardinal Richelieu... **DON'T FORGET TO FOLLOW THESE LINKS!** 1) To support the podcast financially in r...

30YearsWar #58: Out With The Old 25.05.2022

We're ten years old! Wish WDF a happy birthday by buying the NEW and IMPROVED edition of Matchlock and the Embassy! The death of Gustavus Adolphus at Lutzen cast a long shadow over the year 1633. Could the Swedes rebound, and consolidate their gains, or would the Emperor avenge himself on his ungrateful subjects, after a worrying season of setbacks? As it turned out, nothing came easy to either si...

30YearsWar #57: The Lion at Lutzen 11.05.2022

After going on a tear for 18 months, Gustavus Adolphus had finally caught Wallenstein, in a town just outside of Leipzig. Considering the enormous amount of men under recruitment, their army sizes were somewhat small, but that didn't make the battle any less ferocious. Indeed, Lutzen can be viewed as a turning point, not merely in the conflict here, but also in early modern warfare. The Swedish ca...

"Eight Billion and Counting" - Dr Jennifer Sciubba and Demographic Security 04.05.2022

Real quick - turns out Indira Ghandi is NOT related to Ghandi at all, and is in fact the daughter of Nehru. What are the odds of that? Thanks to Andrew Mence for the correction! For this bonus interview episode, I'm very excited to be joined by Dr Jennifer Sciubba! Here she talks about her new book, 8 Billion and Counting: How Sex, Death and Migration Shape our World - which you can get here! We h...

30YearsWar #56: The Lion and Wallenstein 26.04.2022

With Breitenfeld changing the balance of power in the Empire, Gustavus had much to do as 1631 became 1632. First was the matter of Count Tilly's battered survivors from the battle, who had since been reinforced, and guarded the entrance to Bavaria. But over the horizon was an even greater threat to the Swedish King - Albrecht of Wallenstein, the Holy Roman Emperor's last hope. The two titans faced...

30YearsWar #55: Hear The Lion Roar 13.04.2022

The Battle of Breitenfeld was a turning point in the Thirty Years War, but equally important was what Gustavus Adolphus chose to do after. In his race to conquer, Gustavus tore down the Rhine, seizing a wide range of cities, from Wurzburg, to Mainz, to Frankfurt. In the process, he upset the contract between the Emperor and his subjects like never before, demanding an answer which would come from...

30YearsWar #54: Protestant Germany Joins Sweden 30.03.2022

From the moment Gustavus Adolphus landed in Northern Germany, it was clear that his triumph was impossible so long as the Protestant Electors of Brandenburg and Saxony refused to join his side. Throughout spring and summer of 1631 though, Gustavus' luck finally began to turn, thanks in part to his liberal use of intimidation, and the horrendous miscalculations of the Emperor. Pointing his cannons...

30YearsWar #53: Making A Magdeburg 16.03.2022

Magdeburg, the city where the Thirty Years' War changed. As the Swedes gathered in North Germany, and the Imperials moved to counter them, their paths led to Magdeburg, a city on the River Elbe with a history of defiance. The city fathers of Magdeburg may have believed that their city would serve as the turning point of the war, but what they could never have imagined was the price which would hav...

Russia Invades Ukraine - Has Diplomacy Failed? 09.03.2022

Well, he did it. He actually did it. After month of posturing, years of undeclared war, and even longer lying to our faces, Putin authorised Russia's invasion of Ukraine. How did it come to this? Is Putin the only variable that matters? Does diplomacy still have a chance? Where do I see all of this going? You may not think you need yet another person talking about this war, but just in case you do...

30YearsWar #52: Sweden The Deal 02.03.2022

Get your copy of the second edition of A Matter of Honour: Britain in the First World War! In early 1631, Gustavus Adolphus was in desperate need of allies and subsidies. Fortunately for him, Cardinal Richelieu of France was only too happy to help, but such friendship would come at a cost. France wasn't interested in throwing away good money. Instead, they wanted to effectively sponsor the Swedish...

30YearsWar #49: The Peace in the East 19.01.2022

With Denmark exiting the war in Germany, everything seemed to be looking up Ferdinand in spring 1629, but there was a problem. While on the military front, the Emperor still held the edge, on the diplomatic front, forces were conspiring to turn the war on its head. Cardinal Richelieu recognised that if Sweden and Poland could be brought to the peace table, Gustavus Adolphus would be free at long l...

The Trent Affair #5: From The Brink 31.12.2021

In Episode 5 of the Trent Affair - our final episode, for now! - we ask the big questions, and finish our narrative which stretched across both sides of the Atlantic. At the last moment, it seemed, calmer heads had prevailed, and an Anglo-American War was not required as the price for stained British honour.  But the two sides had come VERY close to such a nightmare, closer, in fact, than the...

The Trent Affair #4: Ultimatum Received 29.12.2021

Listen here to our penultimate episode on the Trent Affair, and the moment when peace or war hung in the balance! After a tense wait, Britain's ultimatum finally arrived in Washington. How would Lincoln and Seward respond to its terms? The Confederate commissioners would have to be returned, and a suitable apology offered, if the British were to be satisfied, but there was room for some manoeuvre....

The Trent Affair #3: Britain's War Plan 27.12.2021

Welcome to our third episode of the Trent Affair, here we confront an important question! Would the Americans choose peace, or would they choose war? The ultimatum had been sent on 2 December. The restrictions of communication meant that the British would be waiting a while for the answer - as much as a fortnight. But, in the meantime, what did the British government do? Incredibly, the British pr...

The Trent Affair #2: For Law And Honour 25.12.2021

Welcome to the second episode of this special miniseries! Happy christmas and thanksss for tuning in! When news of the Trent Affair reached Britain, the British cried foul. The Government made immediate preparations to wrest a satisfactory reply from the Americans. Only the return of the commissioners and an American apology would satisfy Palmerston government. The British people demanded justice...

The Trent Affair #1: Setting the Scene 23.12.2021

Hello and merry christmas history friends and patrons!

30YearsWar #48: The Web of War 15.12.2021

By summer, 1630, the stage had been set for a Swedish intervention in the German War.  But how did Sweden get to the point where this became feasible, or justifiable? What had caused diplomacy to fail between the Habsburgs and Stockholm? What gripes did King Gustavus Adolphus have with the Habsburgs? Would you believe me if a told you that a tangled web of diplomacy is all to blame? Would you...
