The German Peasants’ War was the greatest popular uprising in western Europe before the French Revolution. Like a vast contagion it spread from southwest Germany through Württemberg, Swabia, the Allgäu, Franconia, Thuringia, and Saxony to Alsace in what is now France, Austria, and Switzerland. Peasants massed in armed bands in one region, then another, and rebellion would break out even in areas far away.
