In other respects Guido lost ground. In opposing the growing municipalities he was tempted to strain his authority, with the result that he was defied more than once. Thus on one occasion he ordered his vassals at Modigliana to pull down their houses and rebuild them on the hill for greater safety. For five weeks they resisted, then they destroyed their houses and went to Faenza, which was outside their lord’s jurisdiction. This led to a war between the Count and the city of Faenza which extended over years. On another occasion he went to Camaldoli and carried off all the weapons which he found there to Poppi. He restored them afterwards, but only in return for an enormous amount of grain. Again he disputed with the nunnery of Rosano and won his suit, but in this case Countess Gualdrada carried the decision in person to Rosano, and declaring it annulled she tore it up. The acts of Guido Vecchio were such that the Pope wrote to him in his old age urging him to reform his ways, but even the warnings of a Pope were defied with impunity by these barons. When Count Guido Vecchio died in the year 1213, the family split into five branches, each of his sons taking the name of count of the chief stronghold which fell to his share. Poppi in the first instance fell to Count Guido Magnifico of Bagno, then to his sons Guido Novello and Simone. The acts of these brothers, and the enmity which arose between them, take us into the very thick of the contentions which agitated Florence in the thirteenth century.
