The History of Cologne

In 1275, Cologne entered an unexpected agreement that reshaped its relationship with one of the most powerful men in the empire: the new Archbishop of Cologne. At the same time, the city received a remarkable new Gothic seal—an object that tells us more about medieval identity, politics, and ambition than any charter ever could. How did all this come together? And why did it matter so much? Join us as we follow the early moves in a story that will echo all the way to Worringen.

1271: Three years after civil war tore Cologne apart, the aging Dominican friar Albertus Magnus was sent to end the deadlock between a captive archbishop and an ambitious count. But peace always comes at a cost — and in Cologne, that cost would change the balance of power for a century.

On a dark October night in 1268, a secret tunnel, a betrayed alliance, and a struggle for power would decide the fate of medieval Cologne. What began as a feud between wealthy families turned into a bloody street battle beneath the city walls. Who dug the hole—and who paid the price? Join us as we uncover the forgotten story of the Battle of Ulrepforte.

In this retrospective episode, we explore how medieval Cologne’s citizens gradually challenged the authority of their archbishops, built their own institutions, and laid the foundations for urban independence in the High Middle Ages.

Cologne, 1265 — a city under siege, its streets brimming with unrest and uneasy alliances. When political grudges spill over into the night, strange visions, whispered plots, and a deadly dance leave their mark on the medieval metropolis. In this episode, we follow an archbishop who can’t stop picking fights, a city that won’t bow, and the shadowy hands fanning the flames in between.
