  • The Wendish Crusade
    Feb 5 2026

    In this episode, we begin our series on the High Medieval Empire by focusing first on its northeastern frontier, where many factors would coalesce into a sudden, and permanent, push to the east by Saxons and Danes into the lands of the Slavic Wends. The whole phenomenon has been summarized into the "Wendish Crusade", despite the crusade only lasting a single season of a many decades long process. Over the course of these momentous decades, warring forest tribes would transfer into a vast amount of pluralistic, though German, identities, including the rising Hanseatic League.

  • Series 11: Staufer Revival (1125 - 1250 AD)
    Jan 30 2026

    In this series, we discuss how the Holy Roman Empire will change in the long term from its warrior foundings, to a transpersonal and permanent institution of Inner Europe. This process would be personified by the Staufer dynasty, who would work to pick up the fragments of the investiture struggle and rebuild a new society.

  • Hungarian-Croatian Union; A New Danube
    Dec 22 2025

    In this episode, we continue our survey of Inner Europe during the Investiture Struggles by examining the rules and administrations of many consolidating duchies and kingdoms, including Swabia, Bavaria, Austria, Carantania, Hungary, Croatia, and Duklja. As survival becomes less of a concern, confirming the co-rule of a region's traditions takes the top priority.

    In this episode, we look at 4 independent short stories, linked through a similar setting and time, that of the warband states of Eastern Central Europe in the changing times of the Investiture Controversy. All will face an interesting historical cycle, a fall and rebirth, which will result in a new place for the warriors of the realm in a greater and lesser military aristocracy.

  • The Investiture Controversy
    Nov 24 2025

    In this episode, we finally reach the climax of simmering tensions between papal and imperial authority over the western church. A reform movement, built on reaction against urban decadence in the Mediterranean, Burgundy, and Lorraine, clashes with the imperial church, built on converting, militarizing, and bringing order to the rough Inner European frontier. Some of the largest personalities in Medieval History become involved, and the consequences will take a couple episodes to unpack.

  • High Medieval Identity and Society
    Nov 3 2025

    In this episode, we set up the context in which our next few series are to take place. The High Middle Ages will be a time of immense transformation for Inner Europe, a time where the world before and after would be almost unrecognizable. Still, it affected Inner Europe's many different societies in many different ways, and would present challenges as well as opportunities.

  • The Wars of Lech, Czech, Rus (and Arpad)
    Oct 20 2025

    In this episode, we catch up with the development and Christianization of Rus Civilization, and discuss its hybridization with the other societies of Inner Europe. In doing so, we introduce some of the dynastic conflicts, rapidly changing peripheral strongholds, and family ties that the non-imperial powers of Inner Europe would develop amongst themselves just prior to the flourishing of the High Middle Ages.
