A brief civil war fought in Switzerland from November 3 to 29, 1847, between the Sonderbund, a defensive alliance of seven Catholic cantons, Lucerne, Fribourg, Valais, Uri, Schwyz, Unterwalden and Zug, and the liberal majority of the wider Swiss Confederation. The immediate dispute was religious and institutional: the federal diet had closed monasteries in Aargau in 1841 and pressed for the expulsion of the Jesuit order from Swiss territory generally, and when Lucerne instead invited Jesuits to run its schools, the seven Catholic cantons formed the Sonderbund to defend their own religious institutions against the centralizing federal majority. General Guillaume Henri Dufour led a federal army of roughly one hundred thousand against the Sonderbund's smaller forces and defeated it within four weeks with unusually restrained conduct on both sides, a restraint credited by historians with keeping the fighting brief.
Facts
Consequences
What It SettledThe federal army defeated the Sonderbund's forces canton by canton over four weeks, and the alliance formally dissolved on November 29, 1847. The war's outcome reshaped Switzerland: the 1848 federal constitution transformed the loose confederation into a federal state with a central government, and it constitutionally barred the Jesuit order from operating anywhere in Switzerland, a ban that stood for more than a century. The restraint both armies showed toward captured soldiers and civilians during the fighting is credited by historians as an influence on Henry Dunant, a Genevan who went on to found the International Red Cross a little over a decade later. 1 Religious DimensionThe war's immediate cause was religious and institutional. The federal diet's 1841 closure of Aargau's monasteries and its campaign to expel the Jesuit order from Swiss territory were read by the seven Catholic cantons as an attack on their own religious institutions, and Lucerne's decision to invite Jesuits to run its schools rather than comply was the specific act that triggered the Sonderbund's formation. The war is properly read as a conflict over the place of Catholic religious institutions, monasteries and Jesuit education, within an increasingly centralized and secularizing Swiss state, rather than as a war between two rival confessions each seeking to displace the other: the federal majority's own program was centralization and secular liberalism rather than the establishment of Protestantism. 1 Disputed
Death TollSwiss military records tally ninety three dead in action across both sides, sixty federal soldiers and thirty three Sonderbund defenders, the figure the Historical Dictionary of Switzerland gives for combat deaths during the twenty six days of fighting. Death TollGeneral histories of the war round the toll upward to allow for wounded soldiers, several hundred on each side, who later died of their injuries after the fighting itself had ended, a figure Remak's account also treats as the more complete one. The Event
When It Happened Principal PartiesThe Sonderbund, a defensive league of the seven Catholic cantons of Lucerne, Fribourg, Valais, Uri, Schwyz, Unterwalden and Zug, commanded by Colonel Jean Ulrich de Salis Soglio, against the federal army of the wider Swiss Confederation, commanded by General Guillaume Henri Dufour and drawn chiefly from the sixteen cantons that made up the liberal federal majority. 1 Status

The Sonderbund War and the Making of Federal Switzerland
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 Sonderbund War grew directly out of a dispute over Catholic religious institutions within an increasingly centralized and secularizing Swiss state. The federal diet had closed Aargau's monasteries in 1841 and pressed for the Jesuit order's expulsion from Swiss territory generally, and when the canton of Lucerne responded by inviting Jesuits to run its schools rather than comply, seven Catholic cantons, Lucerne, Fribourg, Valais, Uri, Schwyz, Unterwalden and Zug, formed the Sonderbund, a defensive league, to protect their own religious institutions against the federal majority.
Fighting broke out on November 3, 1847, when General Guillaume Henri Dufour led a federal army of roughly one hundred thousand against the Sonderbund's smaller forces, and the war ended in less than four weeks with the alliance's formal dissolution on November 29. Its consequences reshaped the country: the 1848 federal constitution transformed Switzerland from a loose confederation into a federal state with a central government, and it constitutionally barred the Jesuit order from operating anywhere in the country, a ban that stood for more than a century afterward.
A Brief War's Long Shadow: Restraint and the Origins of the Red Cross
This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
Both armies in the Sonderbund War showed unusually restrained conduct toward captured soldiers and civilians, a discipline historians credit with keeping a war fought between two hundred thousand armed men to under four weeks and comparatively few dead. No international body has made a genocide or crimes against humanity determination for the fighting, and none was warranted by the era's own standard: casualties were low by the measure of nineteenth century civil conflicts, and the defeated cantons were reintegrated into the new federal state rather than punished as a conquered enemy once the war ended.
That restraint carried a consequence its combatants could not have anticipated. Henry Dunant, a young man from Geneva at the time of the fighting, is understood by historians to have drawn on the war's comparatively humane conduct as part of what shaped his thinking a little over a decade later, when the horror he witnessed on a very different battlefield led him to found the International Committee of the Red Cross. A brief Swiss civil war fought largely over Jesuit schools left, indirectly, one of the founding threads of modern humanitarian law.
Cross-Tradition Connections
Associated With
The federal majority that opposed the Sonderbund was drawn largely from Protestant cantons, though the federal cause was secular centralization and confiscation of Catholic institutions rather than the establishment of Protestant doctrine, and several federal cantons and soldiers were themselves Catholic.
Belongs to Tradition
The war's immediate cause was the federal diet's closure of Aargau's monasteries and its campaign against the Jesuit order, which the seven Catholic cantons read as an attack on their own religious institutions. The Sonderbund formed to defend those institutions rather than to impose Catholicism on the wider Confederation.
