Julius II was quick to oppose the ' and convoked a general council by a papal bull of 18 July 1511, which was to meet on 19 April 1512 in the Archbasilica of St. John Lateran, in Rome. The bull not only was a canonical document but also was polemical in content. Julius refuted the allegation by the cardinals for their Pisa '. He declared that his promise before his election as pope was sincere; that since he became pope, he had always sought to call a general council; that to prepare the general council, he had endeavored to bring an end to quarrels between rulers; that subsequent wars had made calling the council inopportune. Julius then reproached the participants at Pisa for their lack of respect by calling a council without the pope, who was supposed to lead. He also said that the three months of preparation for Pisa was not enough. Finally, he declared that no one should attach any significance to the statements made at Pisa.
