This war was followed by another of a much more serious nature. The German peasants had grievances compared with which those of the knights and lesser barons were imaginary. For about a century several causes had tended to make their condition worse and worse. While taxes and other burdens were increasing the power of the king to protect them was decreasing; with or without the forms of law they were plundered by every other class in the community; their traditional privileges were withdrawn and, as in the case of the knights, their position had suffered owing to the introduction of Roman law into Germany. In the west and south-west of the country especially, opportunities of migration and of expansion had been gradually reduced, and to provide for their increasing numbers they were compelled to divide their holdings again and again until these patches of land became too small for the support of a household. Thus, solely under the influence of social and economic conditions, various risings of the peasants had taken place during the latter part of the 15th century, the first one being in 1461, and at times the insurgents had combined their forces with those of the lower classes in the towns, men whose condition was hardly more satisfactory than their own. In the last decade of the 15th and the first decade of the 16th century there were several insurrections in the south-west of Germany, each of which was called a _Bundschuh_, a shoe fastened upon a pole serving as the standard of revolt. In 1514 Württemberg was disturbed by the rising of "poor Conrad," but these and other similar revolts in the neighbourhood were suppressed by the princes. These movements, however, were only preludes to the great revolution, which is usually known as the Peasants' War (_Bauernkrieg_). The Peasants' War.
