Germs of civil discord were not lacking, and these soon developed so as to divide Florence into factions, the two chief of these being the Whites, who were favourable to popular liberty, and the Greys, who were adherents of the Medici. The latter were dangerous and treacherous enemies of Savonarola and of the Republic. For a time the Prior's preaching confounded his foes, for it completely changed the aspect of the city. The women cast off their jewels and dressed simply; young profligates were transformed into sober, religious men, the churches were filled with people at prayer, and the Bible was diligently read. Now came danger from without. The departure of the French had endangered the security of Florence. The Pope and Venice desired the reinstatement of the fallen tyrant Pietro de' Medici, and he prepared to attack the city. But he was foiled by the energy to which the Prior roused the Florentines for measures of defence. Meantime, Savonarola once more displayed his noble independence by spurning the offer on the part of the Pope of a Cardinal's hat. And terrible in their vehemence and audacity were his denunciations against the vices of Rome, delivered in his Lenten sermons of 1496. In his usual strain, but with increasing power, Savonarola graphically and vividly described the woes of Italy, as though he were gifted with prophetic vision. One of his sermons was interdicted by the Pope, but the preacher modified nothing and defied the Vatican. And now, while the enthusiasm of his followers was developing into fanaticism, the hatred of his enemies was approaching a climax, and the war was waxing furious. The fame of this marvellous preacher was now extending throughout the world by means of his printed sermons. Even the Sultan of Turkey commanded them to be translated into Turkish for his own study. Of course the individual aim of Savonarola was simply to be the regenerator of religion. The Florentines, however, adulated him as the real founder of the free Republic. Hence they displayed immense ardour in defending him against the Pope, seeing that thus they were upholding their own freedom, because the Pope was aiming at reinstating the Medici in Florence. The Pope had hoped that the Prior would moderate his tone, but this was only more aggressive than ever, and threatening messages arrived from the Vatican. Attempts by his friends, some of them of high and influential position, to defend him, only the more enraged Pope Alexander Borgia. He summoned a consistory of fourteen Dominican theologians who were ordered to investigate Savonarola's conduct and doctrine. The strange issue was he was charged with having been the cause of all the misfortunes that had befallen Pietro de' Medici.
