This trial, which caused considerable attention in its day, proved quite as prejudicial to the citizens as to the Jews themselves. Immediately after the inquiry began, several Jews of Ratisbon had betaken themselves to Bohemia and to the emperor, and tried by every means to save their unhappy brethren. They knew that to explain their righteous cause gold, and plenty of it, would be above all things necessary. For this reason several Bavarian rabbis assembled in a synod at Nuremberg, and decided that the Bavarian communities and every individual not absolutely impoverished should contribute a quota to make up the amount necessary to free the accused Jews of Ratisbon. When the safety of their brethren was in question, the Jews, however fond they might be of money, were by no means parsimonious. The intercession of the Bohemian nobles under whose protection several of the Ratisbon community had placed themselves led to no result. Far more efficacious were the golden arguments which the ambassadors of the community laid before Emperor Frederick and his advisers. It is only just to say that this usually feeble sovereign displayed considerable ability and firmness in this inquiry. He was so strongly convinced of the falsehood of the blood accusation against the Jews that he would not allow himself to be deceived by any trickery. He dispatched rescript after rescript to the council of Ratisbon, ordering the immediate release of the imprisoned Jews, the cessation of the durance of the community, and the restoration of their property. The council, through fear of the bishop and the duke, delayed the execution of the order, and the emperor became furious at the obstinacy of the citizens when news was brought to him that, in spite of the imperial command, they had already executed some of the Jews. He thereupon declared the city to have fallen under the ban of the empire on account of its obstinate disobedience, and summoned it to answer for its contumacy. At the same time he sent the imperial chancellor to deprive the city of penal jurisdiction and to threaten it with other severe penalties.
