In 1833, the Swiss city-republic of Basel separated into two distinct cantons. During the three-year period known as the “Troubles” (Wirren), landowners in the countryside, inspired by the French July Revolution of 1830, rebelled against the city government. The roots of the division, however, run deeper in Basel's religious and theological culture and also reflect the outgrowth of the German Confederation's “persecution of demagogues.” This article examines these neglected aspects of the cantonal division, showing the importance of Christianity, and the complex politics of Protestantism, in Europe's revolutionary century.
