Episode Details

Welcome to Season 3 of the History of the Germans, diving into one of the most dramatic and consequential periods of medieval German history — the age of the Hohenstaufen. But before the Hohenstaufen can take centre stage, someone else has to get out of the way first.

It is 1125, and the Salian dynasty is dying with Emperor Henry V in the palace of the Bishop of Utrecht. After a century of Salian rule — marked by civil war, the Investiture Controversy, and a catastrophic weakening of imperial authority — the princes of the realm face a fundamental question: what is an emperor actually for?

In this episode, we set the scene for the next great chapter of German medieval history by exploring the three strategies available to any new emperor seeking to rebuild royal power, and then watch as those strategies are tested almost immediately — at one of the most chaotic and dramatic royal elections the Holy Roman Empire ever produced.

At Mainz in August 1125, four great dynasties — the Hohenstaufen, the Welf, the Babenberg, and the Supplinburg — converge to elect a new king. What follows is a masterclass in medieval political theatre: tearful refusals, procedural confusion, a man jumping on a horse at entirely the wrong moment, and a last-minute betrayal that will echo through German and Italian politics for the next 150 years.

Topics covered in this episode:

• The collapse of Salian imperial authority and the legacy of the Investiture Controversy
• The three strategic options facing any new Holy Roman Emperor
• The key players at the election of 1125: Lothar of Supplinburg, Frederick of Hohenstaufen, Henry the Black of Bavaria, and Leopold of Austria
• Why not wanting the crown was the surest way to win it
• The Welf betrayal that ignited the Guelf vs Ghibelline conflict across medieval Europe
• The election of Lothar III — and why the age of the Hohenstaufen paradoxically begins without one
