 Paolo was considered a candidate for the papacy ("papabile", in Curial terminology) in the Conclave that followed.It was said that the leader of this alleged movement was Cardinal Alessandrino (Michele Bonelli), the great-nephew of Pius V. Although his cause was supported by Cardinal Carlo Borromeo, and some others, it was strongly opposed by the Grand Duke of Florence, Cosimo III, whose agents were able to enlist the support—or rather the opposition—of some of the cardinals who had been created by Pius IV and Pius V. Both Burali and Borromeo were known to be uncompromising personalities, and enthusiastic for the immediate implementation of all of the decrees of the Council of Trent.Both would be difficult to deal with if either was pope, in negotiations with the rulers of various European principalities.
