born 1479
died March 17, 1516, Florence
Ruler of Florence (1512–13).
A member of the elder branch of the Medici family , he was the son of Lorenzo de' Medici . In 1494 his brother, Piero de' Medici, was ousted as ruler of Florence by the republicans, aided by the French. In 1512 Pope Julius II demanded that Florence enter his Holy League against France and allow the exiled Medici to return to Florence. Giuliano returned as ruler (Piero having died in 1503) and used harsh measures to suppress a conspiracy. In 1513, after another brother became Pope Leo X , he went to Rome as a cardinal. In 1515 he received the French title of duke de Nemours.
