In spite of this, lack of industrial occupation, the difficulty and even sometimes the entire absence of public supervision, and, in part also, the ease with which alms were to be had, bred a large crop of beggars, who moved about from place to place and who, in late mediæval times, became a perfect plague throughout the whole of Germany. Hence all the greater towns in the 15th century and early years of the 16th issued special regulations to deal with the poor. In the matter of these laws for the regulation of charity the city-fathers acted independently, strong in the growing consciousness of their standing and duties. Lay Guardians of the Poor were appointed by the magistrates and poor-boxes were established, the management of which devolved on the municipal authorities. The Catholic Netherlands set an excellent example in this respect by utilising the old hospital regulations and, with their help, drawing up new and independent organisations. Antwerp, Brussels, Louvain, Mechlin, Ghent, Bruges, Namur and other towns already possessed a well-developed system of poor relief. “The admirable regulations for the relief of the poor at Ypres” (1525), to which reference is so often made, “a work of social reform of the first rank” (Feuchtwanger), sprang from such institutions, and these, in turn, were by Charles V in 1531 made the basis of his new Poor Law for the whole of the Netherlands. The Ypres regulations declared, that, according to the divine command, everyone is obliged to gain his living as far as he can. All begging was strictly prohibited, charitable institutions and private almsgiving were not allowed to have their way unchecked, admission of strangers was made difficult and other salutary restrictions were enforced, yet, on the other hand, Christian charity towards those unable to earn a living was warmly welcomed and set in the right channels.[133] In the Netherlands, Humanism, which had made great progress in Erasmus’s native land, co-operated in the measures taken, and it was here that the important “_De subventione pauperum_” of Juan Ludovico de Vives, a friend of Erasmus, of Pope Hadrian IV and of Sir Thomas More, and a zealous opponent of Lutheranism, was published in 1526.
