The German Peasants' Revolt of 1525 represented an unprecedented challenge to the princes and other petty political rulers of the areas involved. While localized uprisings had occurred with increasing frequency in the decades prior to the 1525 revolt and an uneasy awareness of growing levels of peasant discontent was widespread among most rulers of southern and central German lands, the extent of the major rebellion that developed in early 1525 took everyone by surprise. No one was prepared to respond, either militarily or through more peaceful means. Even the Swabian League, the peacekeeping alliance of Imperial princes, prelates, nobility, and cities that eventually assumed primary responsibility for suppressing the revolt, did little to mobilize its resources for almost six months after the first appeals for help from its members against disobedient subjects reached it. When the League did mobilize, its decision created further problems for League members, since most sent their required contingents to the League's forces only to discover that they needed the troops badly themselves once the revolt spread to their own lands. Since the Council of the Swabian League adamantly refused to return any members' troops because this would hinder the League's own ability to suppress the peasant disorders, many members found themselves virtually defenseless against the rebels.
