Politics and world events

The Pazzi Conspiracy in Florence

  • April 26th : With the Pazzi conspiracy of the Florentine nobility, the ruling Medici family is supposed to be disempowered as de facto rulers of Tuscany through the murder of their head Lorenzo il Magnifico and his brother and co-regent Giuliano di Piero de 'Medici . They are to be replaced by Francesco de 'Pazzi and Girolamo Riario , a nephew of Pope Sixtus IV . The attack failed, Giuliano fell victim to the attack on Easter Sunday during high mass in the Cathedral of Santa Maria del Fiore , but Lorenzo escaped injured. The angry Florentines then kill the conspirators they can seize. Jacopo de 'Pazzi is pushed out of a window, pushed naked through the streets of the city and thrown into the Arno . The Pazzi family were stripped of their Florentine possessions and every trace of their name was erased. Co-conspirator Francesco Salviati , although Archbishop, is hanged on the walls of the Palazzo della Signoria . Lorenzo manages to save Cardinal Raffaele Riario , a nephew of the Pope who almost certainly had nothing to do with the conspiracy, as well as two relatives of the conspirators. The escaped participants are chased across Italy. However, one of the main bombers, Bernardo Bandini Baroncelli , managed to escape to Constantinople.
  • Florence is placed under Interdictum by the Pope for killing the Archbishop , so reading Mass and Communion is forbidden. Sixtus obliges the Pope's traditional military arm to attack the King of Naples , Ferdinand I , Florence. With no help from his usual allies, Bologna and Milan , Lorenzo is forced to save himself through the day with skillful diplomacy. He sails to Naples and falls into the hands of Ferdinand, who holds him prisoner for three months before he releases him with presents.
