The Pazzi family attack Lorenzo de' Medici and kill his brother Giuliano during High Mass in Florence Cathedral.
The Pazzi were a noble Florentine family. Their main trade during the fifteenth century was banking. In the aftermath of the Pazzi conspiracy in 1478, members of the family were banished from Florence and their property was confiscated; the family name and coat-of-arms were permanently suppressed by order of the Signoria.
