Pazzi conspiracy

The Pazzi conspiracy was a plot by members of the Pazzi family and others to displace the de' Medici family as rulers of Renaissance Florence. On 26 April 1478 there was an attempt to assassinate Lorenzo de' Medici and his brother Giuliano de' Medici. Lorenzo was wounded but survived; Giuliano was killed. The partial failure of the plot served to strengthen the position of the de' Medici. The Pazzi were banished from Florence.
