BARTOLOMMEI, MARQUIS FERDINANDO (1821 1869), Italian revolutionary, belonged to an old and noble Floren tine family. In 1847-48 his house was a centre of revolutionary committees, and during the brief constitutional regime he was very prominent. After the return of the grand duke Leopold II. he became a conspirator on behalf of Italian freedom and unity, allying himself with the popular party and quitting the semi Liberal nobles. On the outbreak of war between Piedmont and Austria he worked hard for the overthrow of the grand duke, and on April 27, 1859, Florence rose as one man, the troops refused to fire on the people, and the grand duke departed, never to return. A provisional government was formed and Bartolommei elected gonfaloniere. In the summer elections were held, and on the meeting of parliament Bartolommei's unitarian views prevailed, the assembly voting the resolution that the house of Lorraine had forfeited its rights and that Tuscany must be united to Italy under King Victor Emmanuel. Bartolommei was made senator of the Italian kingdom and received various other honours. His last years were spent in educational and philanthropic work.
The best biography of Bartolommei is contained in Il Rivolgimento Toscano e l'azione popolare, by his daughter Matilde Gioli (Florence, 19o5).
