A few years later, however, Calvinism, spread by Swiss and French disguised predicants, began to make considerable progress among the rural population of the Western and Northern provinces. The Calvinists, like the Anabaptists, did not believe in freedom of conscience. They opposed the fanaticism of the Spanish inquisition with the fanaticism of the Reformers and opened the fight without any idea of conciliation. They distributed satiric pamphlets, secretly printed, in which the Church and the court were grossly caricatured, and their loathing for the worship of the Virgin and the Saints degenerated into blasphemy and sacrilege. They found very little favour among the educated classes, but made a number of converts among the discontented proletarians, who led a very miserable life in the neighbourhood of the most important industrial centres. To counteract this propaganda, Charles issued a new "placard," in 1550, which forbade the printing, selling or buying of reformist pamphlets, together with any public or private discussion on religious matters. Even to ask forgiveness for a heretic or to abstain from denouncing him was considered as a crime punishable by death and confiscation of property. Half of the fortune of the condemned went to the denunciator, the other half to the State. Only in one quarter, in the nominally independent bishopric of Liége, where Erard de la Marck issued similar decrees, was the repression successful. Everywhere else, the number of new proselytes increased with that of the executions, and when the emperor abdicated, it seemed evident that a war of religion could not be averted. This war was destined to break up Belgian unity, which had only just been entirely achieved. This might have been averted if Belgium had been allowed to cope with the Reformation crisis in all independence, according to the social conditions of the time, like other European States. A truly national prince and Government would, no doubt, have succeeded in keeping the country together, but Belgium no longer enjoyed the advantage of being ruled by national princes. Hapsburgian dynastic principles had conquered Burgundian traditions. Orders no longer emanated from Brussels but from Madrid, so that to the obstacles created by religious differences and class hatred was added the bitter conflict between patriots and foreign rulers.
