Pazzi conspiracy
As the opening stroke of the Pazzi conspiracy, Giuliano was assassinated on Easter Sunday, 26 April 1478 – in the Duomo of Florence, Santa Maria del Fiore, by Francesco de' Pazzi and Bernardo Baroncelli. He received a fatal sword wound to the head and was stabbed 19 times. He died laying on the cathedral floor. Lorenzo, who had escaped to the Medici palace, did not learn of his brother's death for several hours.
