Baden Disputation (1526)
Zürich’s reforms alarmed Catholic cantons that hoped to preserve the old faith across the Confederation, making the choice of Baden as the venue consequential. The Catholic cantons of the Swiss Confederation convened a disputation at Baden from May into June 1526. Johann Eck, who had opposed Luther at Leipzig, defended the old teaching. Zwingli did not attend; Johannes Oecolampadius of Basel and Berchtold Haller of Bern spoke for reform. The disputants argued over the Mass, images, saints, and the authority by which doctrine should be judged. Zwingli’s absence was not simply a refusal to debate: Zürich objected to the venue and feared for his safety. The terms of attendance became part of the dispute over which side could claim a fair hearing.1

The Debate and Its Outcome
The Catholic majority declared its position victorious and pressed for action against reforming preachers. Yet the exchange made the rival claims clearer to listeners and readers. Oecolampadius’s appeal to Scripture remained influential even where the immediate decision went against him. The dispute also showed how the place, judges, and composition of an assembly could affect its result.2
Why It Matters
Baden did not heal the Swiss division. Its consequences reached beyond the conference: Bern’s subsequent disputation took place in a different political setting, and Basel later adopted reform. The Reformation’s growth cannot be read simply from the verdict announced at the close of a debate.
