Two armed confrontations between Reformed Zurich and the Catholic cantons of the Swiss Confederation, in 1529 and 1531, fought over the Reformation's spread into the jointly governed Mandated Territories that Zurich and the Catholic cantons administered together. The First War of Kappel began in June 1529 after Catholic authorities in Schwyz executed a Reformed preacher, Jacob Kaiser, for heresy; Zurich, having adopted Huldrych Zwingli's Reformation, mobilized its forces, but a peace was negotiated at the border village of Kappel am Albis before fighting began, commemorated in Swiss memory by the legend of the Kappeler Milchsuppe, a shared pot of milk soup said to have been eaten across the border line by troops of both sides while the terms were settled. The Second War of Kappel followed in October 1531, after continuing tension and an economic blockade Zurich had imposed on the Catholic cantons; the Catholic cantons declared war and marched on Zurich, whose hastily raised militia, including Zwingli himself serving as an army chaplain, was routed at the Battle of Kappel on 11 October 1531.
Facts
Consequences
What It SettledThe First Peace of Kappel (25 June 1529) ended the standoff without fighting, on terms allowing each canton to determine its own religious confession. The Second War ended in Zurich's defeat, Zwingli's death at the battle and the burning of his body by the victorious Catholic forces as a heretic; the Second Peace of Kappel (November 1531) confirmed each canton's right to choose Reformed or Catholic worship, ended Zurich's expansionist Reformation policy toward the Mandated Territories, and entrenched Switzerland's confessional division between Reformed and Catholic cantons for centuries. 1 Death Toll AssessmentThe First War of Kappel produced no battle deaths: a negotiated peace was reached at the border before the mobilized forces engaged. At the Battle of Kappel on 11 October 1531, the decisive engagement of the Second War, approximately five hundred of Zurich's poorly organized citizen-militia were killed in under an hour, including Zwingli and twenty four Zurich pastors who had accompanied the army as chaplains; Catholic forces suffered comparatively few losses in the rout. 1 Religious DimensionBoth wars were fought directly over which confession, Reformed or Catholic, would govern the Confederation's jointly administered territories, and both sides organized and fought as confessionally defined parties: Zurich under Zwingli's own leadership and, in the Second War, his personal presence in the field as chaplain, and the Five Cantons in explicit defense of Catholic worship against Zurich's economic and political pressure to convert. Gordon situates Zwingli's own aggressive blockade policy, intended to force religious change on the Catholic cantons without open war, as the immediate provocation for the Second War, a reading contemporaries shared: Zwingli was widely blamed within Zurich itself for the disaster that followed. 1 The Event
When It HappenedFirst War of Kappel, June 1529 (no battle); Second War of Kappel, October 1531, decided at the Battle of Kappel on 11 October 1531 1 Principal PartiesThe city and canton of Zurich, having adopted Huldrych Zwingli's Reformation, against the Catholic Five Cantons of Lucerne, Uri, Schwyz, Unterwalden and Zug, with control of the Confederation's jointly governed Mandated Territories as the practical stake in both wars. 1 Status
Official RecognitionNot formally recognized by any body 1 Recognition BasisNo international body has made any determination regarding the Kappel Wars; the modern vocabulary and mechanism for such findings postdate the conflict by centuries. The 1531 Second Peace of Kappel functioned as the era's own settlement, a confessional territorial arrangement negotiated between the Confederation's own cantons rather than imposed or reviewed by any outside authority. 1 Learn More
The Kappeler Milchsuppe and the First War That Never Fought
This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
Reformed Zurich and the Catholic cantons of the Swiss Confederation fought two armed confrontations, in 1529 and 1531, over the Reformation's spread into the Mandated Territories the cantons administered jointly. The First War of Kappel began in June 1529 after Catholic authorities in Schwyz executed the Reformed preacher Jacob Kaiser for heresy; Zurich, having adopted Huldrych Zwingli's Reformation, mobilized its forces in response, but a peace was negotiated at the border village of Kappel am Albis before the two armies engaged.
That negotiated peace produced the Kappeler Milchsuppe, a legend still told in Swiss memory: troops of both sides are said to have shared a pot of milk soup across the border line while the terms of the First Peace of Kappel, signed 25 June 1529, were settled, an agreement that let each canton determine its own religious confession without a battle being fought. The peace held for two years, but Zurich's continuing pressure to spread Reformed worship into the jointly governed territories, the underlying stake in both wars rather than a side effect of either, was not resolved by it.
Zwingli's Death and the Peace That Divided Switzerland by Confession
This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
The Second War of Kappel followed in October 1531, after Zurich imposed an economic blockade on the Catholic cantons intended to force religious change without open war, a policy Gordon identifies as the war's immediate provocation and one contemporaries in Zurich itself blamed Zwingli for. The Catholic cantons declared war and marched on Zurich, whose hastily raised citizen militia, Zwingli himself serving as an army chaplain, was routed at the Battle of Kappel on 11 October 1531: roughly five hundred of Zurich's poorly organized forces were killed in under an hour, including Zwingli and twenty four Zurich pastors who had accompanied the army, against comparatively few Catholic losses.
The victorious Catholic forces burned Zwingli's body as a heretic's. The Second Peace of Kappel, signed the following month, confirmed each canton's right to choose Reformed or Catholic worship, ended Zurich's expansionist Reformation policy toward the Mandated Territories, and entrenched Switzerland's confessional division between Reformed and Catholic cantons for centuries afterward, a division the Confederation's own institutions worked around rather than resolved.
Cross-Tradition Connections
Associated With
The Catholic Five Cantons of Lucerne, Uri, Schwyz, Unterwalden and Zug were the other organized party to both wars, fighting to preserve Catholic worship in the Confederation's jointly governed territories against Zurich's Reformation policy; Gordon records that the First War began after Catholic Schwyz executed a Reformed preacher for heresy. This edge names that community's part as the historical record gives it; it is not an assertion that Roman Catholicism as such initiated the conflict, which Gordon attributes chiefly to Zurich's own expansionist religious policy.
Belongs to Tradition
Zurich fought both wars as the Confederation's leading Reformed city under Huldrych Zwingli's own direction, the historical forerunner of the wider Reformed Protestant tradition; Zwingli was killed serving with Zurich's army at the Battle of Kappel. This edge records Zurich's Reformed community as one of the two organized parties to the wars, exactly as Gordon's account gives it; it is not an assertion that the Reformed tradition as such, beyond Zurich's own policy, caused the fighting.
